C95500 aluminum bronze casting is a nickel aluminum bronze product for loaded bushings, worm wheels, wear rings and engineered pump components. Cable Glands india manufactures metal parts at our CDA 955 Aluminum bronze Casting foundry in Jamnagar, Gujarat, India, serving electrical OEMs, EPC contractors, power utilities and distributors. This grade page covers composition, process selection, international grade comparisons, inspection and drawing-based supply. Enquiries can specify as-cast, semi-machined or fully machined components for evaluation against the selected standard.
Grade identification: C95500 is CDA 955. AB2 is retained as a purchasing search term, but a BS 1400 AB2 order requires separate compliance verification; AB2 and C95500 must not be treated as automatically interchangeable.
C95500 product overview
Nickel aluminum bronze metallurgy
C95500 combines a copper matrix with aluminum, iron and nickel for components that must withstand substantial mechanical loading. Its chemistry differs from both lower-aluminum C95200 and marine-oriented C95800. Nickel is an intentional alloying constituent, so mixed bronze scrap cannot be accepted merely because its colour resembles the specified metal. Cast structure, cooling history and any heat treatment influence the final balance of strength, hardness and ductility. A drawing should therefore identify the material standard and supply condition alongside the UNS grade. This prevents a chemically matching casting from being accepted in an unsuitable metallurgical condition.
Heavy-duty bushings and bearing sleeves
A C95500 bushing is an engineered bearing component, with performance determined by more than the bronze designation. Shaft hardness, surface roughness, alignment, lubricant delivery and running clearance must work together. Thick sleeves may be supplied with machining stock for final boring after mounting, where the design allows it. Flanged bushes require attention to the transition between the flange and barrel because this region can combine feeding difficulty with concentrated stress. For maintenance replacements, provide the mating shaft dimensions and original operating conditions. Worn samples alone do not establish the intended clearance or the original alloy.
Worm wheels, gears and thrust components
C95500 gear blanks and worm-wheel rims are considered where tooth loading and wear resistance drive material selection. The casting drawing should separate the blank geometry from the finished tooth form, hub fit and keyway requirements. Machining allowance is especially important around the rim so that finished teeth remain within sound metal. For composite assemblies, the attachment method between bronze rim and hub requires its own engineering review. A higher hardness value is not automatically beneficial if it sacrifices required toughness. Gear duty, lubrication and mating material remain part of the purchasing specification.
Pump and valve casting requirements
For pump sleeves, impeller components, valve trim and wear rings, C95500 offers a useful combination of mechanical capability and corrosion resistance in compatible media. Fluid composition, temperature, flow velocity and suspended solids should be identified before alloy approval. Pressure-retaining parts require a pressure design and specified inspection criteria; a material designation alone establishes neither a pressure class nor a leak guarantee. Machined sealing faces should be identified on the drawing, with sufficient stock and accessible inspection surfaces. Service experience with another bronze grade should not be transferred without checking the changed chemistry and metallurgical condition.
OEM procurement and repeat-order control
Electrical OEMs and equipment builders can specify C95500 for mechanical hardware within a larger electrical assembly when its strength and environmental resistance suit the design. Its electrical conductivity is substantially below pure copper, so current-carrying functionality needs separate verification. EPC contractors should reference the equipment specification and approved material requisition. Distributors should retain heat identity when breaking larger deliveries into smaller lots. Repeat orders benefit from controlled drawings, retained inspection requirements and clear revision history. These controls keep bushings, brackets, sleeves and replacement blanks consistent even when orders are placed across different projects.

Controlled alloy chemistry
Reliable bronze components begin with verified material identity. Charge materials, returns and alloy additions should be segregated to prevent accidental mixing with leaded bronze, brass or another aluminum bronze grade. Chemical analysis should be linked to the heat number recorded for the delivery. A certificate stating only “bronze” does not provide enough information for controlled OEM purchasing. Include the permitted composition and governing specification in the purchase order. Where restricted substances matter to the end application, request an appropriate declaration or analytical evidence rather than assuming compliance from the alloy family name.
Wear resistance and bearing compatibility
Wear resistance is a system property involving the casting, mating surface and operating environment. Bushes, sleeves, guides and thrust pads need adequate lubrication and correctly defined clearances. Surface finish should suit the intended contact, while edges and lubrication passages should avoid damaging the lubricant film. Specify shaft hardness, alignment requirements and anticipated contamination when these affect the component design. An increase in casting hardness alone does not guarantee longer service life. The inspection plan should cover dimensions and functional contact surfaces as well as any specified hardness range.
Corrosion-resistant engineering surfaces
Aluminum bronze develops a surface film that contributes to corrosion resistance in compatible environments. Performance varies with chemistry, temperature, flow and galvanic contact, so suitability needs evaluation for the actual service medium. For pump and valve components, provide fluid composition and expected operating conditions with the enquiry. Finished surfaces should be protected during storage and transport so that mechanical damage does not compromise assembly. If a coating, passivation procedure or special cleaning treatment is required, identify it expressly. General corrosion resistance should not be presented as universal chemical compatibility.
Machined accuracy and assembly fit
A casting drawing should distinguish as-cast tolerances from final machined tolerances. Bores, bearing journals, flange faces, threaded holes and sealing lands require datums that reflect how the component is assembled. Cast stock must allow for cleanup without unnecessarily increasing machining time or component weight. Thin rings and long sleeves may distort during clamping, so measurement methods should match the agreed inspection condition. Provide surface-roughness requirements only where function justifies them. This approach connects foundry tooling, machining operations and final dimensional acceptance to the same engineering definition.
Traceable supply for industrial projects
Heat identification and drawing revision control help OEMs, contractors and distributors maintain a usable record of each delivery. The required documentation can include chemical analysis, dimensional results and agreed mechanical or non-destructive test reports. Inspection scope should be established before casting because some examinations depend on coupon provision, accessible surfaces or intermediate manufacturing stages. Marking and packaging should preserve identity through subcontract machining and site storage. For repeat orders, reference the approved drawing revision and previous order requirements explicitly. A previous supply does not automatically confirm compliance with a revised project specification.

For C95500, the selected variant should match the specified service rather than a catalogue shape alone. Supply can be discussed for prototype, replacement or repeat-production requirements. Tooling ownership, sample approval and dimensional inspection of first articles should be established before the production batch is released.
Applications in industry
| Customer / industry | Potential use | Engineering check |
|---|---|---|
| Electrical OEMs | Mechanical brackets, clamp bodies and equipment hardware | Load, installation torque and any electrical duty |
| EPC contractors | Pump, valve and plant equipment castings | Approved material requisition and project inspection plan |
| Power utilities | Cooling-water and maintenance components | Service medium, original equipment grade and traceability |
| Distributors | Bushes, sleeves, rings and drawing-based spares | Grade identification and batch documentation |
| Marine and process equipment | loaded bushings, worm wheels, wear rings and engineered pump components | Corrosion conditions, loading and required approvals |
The suitability of C95500 should be confirmed by the equipment designer. For rotating parts, specify balance and concentricity requirements. For sliding components, provide lubrication and mating-surface conditions. For wetted castings, identify fluid chemistry and temperature. These application details help determine whether this grade is appropriate or whether another alloy within the aluminum bronze range deserves comparison.
Manufacturing process and casting methods
Manufacture begins with a drawing and specification review. The foundry assesses section changes, core requirements, feeding paths, machining stock and inspection access. Pattern or die design should then reflect shrinkage and the intended finishing sequence. Material preparation, melting and chemical verification precede controlled pouring. After cooling, the casting is cleaned and examined, with heat treatment performed only where specified and technically appropriate. Machining and final inspection follow the approved route.
| Casting type | Suitable enquiry geometry | Process considerations |
|---|---|---|
| Gravity die casting | Repeat components with feasible die release | Metal die filled by gravity; review tooling cost and thermal control |
| Shell molding | Shaped components needing reproducible mold definition | Resin-bonded sand shell; assess cores, feeding and cleanup |
| Green sand casting | Custom shapes, larger sections and flexible pattern work | Moist sand system; control molding quality, venting and inclusions |
| Centrifugal casting | Bushes, sleeves, tubes and rings | Rotational casting; plan bore cleanup and wall distribution |
| Permanent mold casting | Repeatable shapes suited to reusable metallic molds | Broader process family that includes gravity die casting |
Centrifugal casting can support sound cylindrical components, but it does not guarantee porosity-free metal. All methods require appropriate process control and inspection. Gravity die and permanent mold terminology overlaps and should not imply two unrelated metallurgical processes. For C95200 permanent-mold enquiries, agree a suitable specification explicitly; ASTM B806 does not list every aluminum bronze grade. Casting route availability remains subject to geometry, quantity and technical review.
Quality standards and certifications
| Reference / inspection | How to specify it |
|---|---|
| ASTM B148 | Aluminum bronze sand castings; identify grade and edition |
| ASTM B271/B271M | Copper-base alloy centrifugal castings, where applicable |
| ASTM B505/B505M | Continuous-cast material only when that product form is ordered |
| ASTM B806 | Permanent mold castings for listed grades; verify scope |
| EN 1982 | European cast copper alloy specification when expressly ordered |
| EN 10204 inspection documents | Agree the document type and required validation |
| Dimensional, mechanical and NDT checks | Specify methods, sampling, examination zones and acceptance criteria |
Material standards define requirements; they are not proof that a supplier holds a management-system or product certificate. Request current certificates and verify their scope when certification is mandatory. ISO 9001, marine class, pressure approvals, RoHS and REACH declarations must not be assumed from this product description.

Frequently asked questions
What is C95500 aluminum bronze casting?
C95500, also identified as CDA 955, is a nickel aluminum bronze casting grade considered for loaded bushings, worm wheels, wear rings and engineered pump components. Cable Glands india supplies drawing-based enquiries through its aluminum bronze casting range. Select the applicable material standard and delivery condition alongside the grade.
Is C95500 exactly equivalent to an AB grade?
C95500 is CDA 955. AB2 is retained as a purchasing search term, but a BS 1400 AB2 order requires separate compliance verification; AB2 and C95500 must not be treated as automatically interchangeable. A comparison table is a selection aid; substitution requires checking the complete specifications and obtaining design-authority acceptance.
What is the listed price?
The listed rate is US$ 17.90/Kg. The quotation should confirm the applicable weight basis, quantity, tooling, machining, inspection, packing, freight and taxes. Send the component drawing so that the price basis can be matched to the requested scope.
Which casting methods can be considered?
Gravity die casting, shell molding, green sand casting, centrifugal casting and permanent mold casting can be evaluated against geometry and grade. Gravity die casting is a form of permanent mold casting. Feasibility and the governing product standard must be confirmed for each order.
Can you supply fully machined parts?
Enquiries can specify as-cast, rough-machined or finish-machined components. Include the latest drawing, datums, tolerances, surface finish, threads and inspection requirements. Bores, sealing surfaces and assembly fits should be identified clearly before the casting allowance and machining sequence are agreed.
Are these castings suitable for electrical current paths?
Do not infer current capacity from the word bronze. Aluminum bronze is substantially less conductive than pure copper. An electrical OEM must evaluate conductivity, contact resistance, temperature rise and the applicable assembly tests. Mechanical electrical hardware and current-carrying terminals have different acceptance requirements.
What documents should accompany an order?
Request a heat-linked chemical analysis and the agreed inspection report. Mechanical testing, hardness, pressure testing, microstructure examination and NDT should be specified where needed. EN 10204 documentation type and third-party witnessing must be agreed before manufacture rather than assumed for every delivery.
Are the castings automatically certified for marine or pressure service?
No. Alloy identity alone does not confer marine classification, pressure approval or a certified assembly rating. State the design code, service conditions, acceptance criteria and required approvals in the enquiry. Any certification claim should be supported by a current certificate with an applicable scope.
What information is needed for a quotation?
Send the drawing revision, C95500 specification, quantity, estimated part weight, supply condition, service medium and delivery location. Add any mandatory testing, packaging and project documentation requirements. A sample can support dimensional review, but its original chemistry and design tolerances still require confirmation.
