C95800 product overview
Marine nickel aluminum bronze metallurgy
C95800 is a nickel aluminum bronze with controlled aluminum, nickel, iron and manganese. Its composition is distinct from C95500 even though both are often described as NAB. The iron content must not exceed the nickel content within the specified limits, making the balance between these constituents a practical melt-control requirement. Marine performance depends on the resulting microstructure as well as bulk chemistry. Cooling history and specified thermal treatment therefore deserve attention for thick or complex castings. A procurement document should identify the governing standard, delivery condition and any additional microstructure or corrosion-test requirements.
Seawater pump impellers and wear rings
C95800 is widely considered for seawater pump impellers, wear rings and related hydraulic components. Geometry remains central to performance: inlet conditions, blade profile, operating point and fluid velocity influence cavitation and erosion. No bronze alloy eliminates damage caused by persistent operation outside the intended pump envelope. An impeller enquiry should identify the machined datums, balance requirement and inspection areas. Wear-ring dimensions must account for the mating material and temperature-dependent clearances. For large sections, the foundry needs sufficient information to plan feeding, cooling and any required heat treatment before the final machining sequence is agreed.
Valve bodies, discs and pressure boundaries
Valve bodies, discs, seats and trim in marine water systems may specify C95800 to combine mechanical performance with suitable corrosion resistance. The material specification is only one part of a pressure-equipment requirement. Design pressure, temperature, wall thickness, flange configuration and required test standard must also be defined. Cast surfaces and machined sealing regions may need different examination methods. Hydrostatic testing should state pressure, duration and leakage acceptance criteria. Where welding repairs are permitted, the approval process and qualification requirements should be agreed before production. This keeps the delivery aligned with the valve manufacturer’s design and quality plan.
Offshore hardware and corrosion conditions
Offshore brackets, sleeves, propeller-related parts and marine fittings are exposed to environments that vary substantially between installations. Clean flowing seawater differs from stagnant, polluted or sulfide-containing water. Galvanic coupling to other metals, crevices and local flow acceleration can also influence service life. C95800 should therefore be selected against actual duty rather than a universal claim of seawater immunity. Marine classification or project approval must be requested explicitly. The casting enquiry should identify critical load paths, corrosion allowance where applicable and required examination zones so that these requirements are reflected in the manufacturing plan.
Power utility and Transformer spade Connectors
Power-station cooling-water systems, coastal facilities and EPC water-handling packages create demand for traceable C95800 castings. Buyers need the material description carried consistently from the equipment datasheet to the purchase order and inspection report. Replacement pump parts should preserve the original grade and heat-treatment requirements unless the design authority approves a change. Electrical transformer OEMs may use the alloy for Spade Connectors, and Spade terminals and other mechanical parts in corrosive environments, but its relatively low electrical conductivity requires separate assessment for current paths. Distributors can reduce identification errors by retaining heat numbers and grade markings when packaging smaller quantities for maintenance and site stores.

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 C95800, 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 | seawater pump impellers, valve bodies, marine sleeves and offshore hardware | Corrosion conditions, loading and required approvals |
The suitability of C95800 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. The agreed quality plan can cover chemical analysis, tensile testing, hardness, dimensions, pressure testing and selected NDT. Documented acceptance should correspond to the actual purchase order.

Is C95800 exactly equivalent to an AB grade?
C95800 is CDA 958, a nickel aluminum bronze commonly specified for marine service. Related AB2 and EN grades require specification-by-specification review; similarity does not establish dual certification. 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, C95800 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.
