Detailed product overview
Hydraulic bronze with a defined designation
C83800 bronze casting is used here for UNS C83800, a leaded red brass commonly called hydraulic bronze. Its grade limits differ from C83600 and from the separately registered C83810 alloy. A shortened material name can therefore create uncertainty during sourcing unless the complete UNS number appears on the drawing and purchase order. C83800 is relevant to machined cast hardware and fluid-handling component enquiries, subject to the specified duty. The hydraulic bronze name does not establish a hydraulic pressure class or confirm compatibility with every fluid, seal compound and operating temperature.
Intersecting ports and machined passages
A hydraulic component body can contain several intersecting ports, drilled passages and threaded connections. The casting layout must preserve enough material around each feature after machining, especially where bores approach a parting line or cored cavity. Provide datums for port location and identify burr-sensitive intersections that need cleaning. The finished component should be assessed for leakage using an agreed method when pressure service is intended. Casting soundness and passage cleanliness are separate acceptance issues: removing loose sand does not demonstrate a leak-free wall, and a successful leak test does not prove internal passages are free from machining debris.
Adapters and replacement pump hardware
C83800 machined adapters and pump fittings can be supplied as drawing-based replacements or repeat-production components. For obsolete hardware, record the connection standard, thread form and sealing arrangement instead of copying only the outside shape. A fitting may seal on its thread, a gasket or a machined seat, and the inspection must reflect that mechanism. Cross-referencing to a different national alloy should be handled as an engineering comparison because no exact EN or BS equivalent is asserted here. Keeping the original C83800 designation avoids accidentally buying a similar-looking casting with a different chemistry window.
Cast blanks, rough machining and finished parts
For c83800 components, the delivery condition changes both the manufacturing plan and the inspection scope. A cleaned casting normally retains stock for later machining, whereas a finished part must meet the specified functional dimensions. Rough machining can expose areas that need examination before final finishing. Identify where machining allowance is required and where excess material would interfere with assembly. This is particularly important for hydraulic component bodies, machined adapters, pump fittings and general hardware. The quotation should distinguish pattern or die work from recurring component operations, giving the buyer a clear basis for comparing prototype and repeat-order costs.
Drawing control and mating components
The drawing for c83800 parts should identify a revision, material standard, datums and critical features. A casting outline without a tolerance scheme is insufficient for a fitted component. Bores, bolt circles, sealing lands and thread positions should be dimensioned from functional references. Where several parts are assembled together, their combined tolerances may matter more than an isolated dimension. Share the mating-part requirements when they influence fit or contact. For a replacement order, record deliberate design changes separately from measurements taken from a used sample, especially where wear or previous repair has altered the original surface.

Controlled alloy chemistry
C83800 supply starts with identified charge material and a controlled specification. Ingot, approved returns and alloy additions should be kept traceable, particularly where visually similar grades are processed. A heat analysis verifies composition; it does not by itself demonstrate the quality of every cast section. The purchase order should identify the required chemistry report and any restrictions on residual elements. When remelt material is used, its suitability belongs in the foundry control plan. Retaining material identity through machining helps ensure that the finished component remains linked to its original inspection evidence.
Machined bores and bearing surfaces
Bored c83800 parts require a defined relationship between the bore, outside diameter and mounting faces. Turning a diameter to size does not automatically establish concentricity or perpendicularity. State the intended measurement condition, especially for thin sleeves or split liners that can distort under clamping. Bearing surfaces also need an appropriate finish and edge treatment. If the part is pressed into a housing, identify whether sizing occurs before or after installation. The machining and inspection sequence can then follow the functional fit instead of checking an unloaded component in an unrelated condition.
Threads, sealing lands and flange faces
Threaded c83800 components need the connection standard, gauge requirement and sealing mechanism to be stated clearly. A tapered pipe thread, a parallel thread with gasket and a metal-to-metal seat are different interfaces. Casting stock should allow full cleanup at the sealing surface without reducing wall thickness below the design requirement. Specify burr removal around intersecting holes and protect finished threads during handling. For pressure duty, dimensional acceptance and leakage testing serve different purposes. Both should be defined where necessary, along with any restrictions on repairs or post-casting treatments.
Wear parts and service compatibility
Material selection for c83800 wear parts should account for the mating surface, lubricant, contamination and operating conditions. A harder alloy is not always the better bearing choice, and lead content does not establish a maintenance-free running surface. Fluid-contact components need a separate assessment of medium, temperature and flow. Provide realistic duty information instead of a broad description such as heavy duty or corrosion resistant. This allows the component designer to decide whether the selected grade is appropriate and whether a different bronze family deserves comparison before tooling and machining are committed.
Inspection records and batch identification
Traceable c83800 parts should carry the agreed identity through casting, machining, inspection and dispatch. The required marking may be on the part, an attached tag or the packaging, depending on size and the drawing. Certificates should reference the relevant order and heat rather than an unrelated material sample. Dimensional reports are most useful when they follow a numbered drawing and identify the measuring condition. Agree whether individual or batch records are needed, and identify any witness points early. These practical details reduce uncertainty when components arrive at an OEM assembly line or project store.

Applications in industry
| Customer / sector | Potential component duty | Main design check |
|---|---|---|
| Electrical OEMs | Equipment hardware and mechanical support components | Mechanical load; separate verification if current-carrying |
| EPC contractors | Plant fittings, pump components and specified bronze parts | Approved material requisition and project inspection plan |
| Power utilities | Maintenance sleeves, liners and auxiliary equipment parts | Original equipment specification and service conditions |
| Distributors | Grade-identified cast and machined replacement parts | Batch identity and customer-specific requirements |
| Machinery manufacturers | Bearing and sliding components where grade is suitable | Load, speed, lubrication, shaft and housing condition |
Manufacturing process and casting methods
Manufacture begins with drawing review, followed by alloy and process selection, tooling preparation, melting, pouring and controlled cooling. Castings are cleaned before the agreed machining and inspection stages. The route for C83800 must reflect geometry and acceptance requirements. High-lead grades require particular attention to lead distribution; a process name alone does not guarantee uniformity or freedom from porosity.
| Process | How it works | Selection considerations |
|---|---|---|
| Investment casting | An expendable pattern forms a ceramic mold for detailed geometry | Review alloy suitability, tooling, section changes and inspection; qualify before production |
| Green sand casting | Molten alloy fills a cavity formed in moist bonded sand | Flexible for shaped parts; control cores, venting, feeding and machining stock |
| Permanent mold casting | A reusable metallic mold defines the casting cavity | Review release, thermal balance and suitability of the selected alloy |
| Shell molding (resin sand) | Resin-bonded sand forms a rigid shell mold | Evaluate repeatability, core design, cleanup and dimensional requirements |
| Centrifugal castings | Rotation distributes molten metal in cylindrical tooling | Useful enquiry route for rings and sleeves; review lead segregation and bore cleanup |
| GDC — gravity die casting | Gravity fills a reusable metal die | A permanent-mold process, not high-pressure die casting; assess geometry and volume |
After casting, turning and boring establish cylindrical datums; milling, drilling and threading create the remaining functional features. Intermediate checks can be planned before expensive finishing. Final cleaning should remove residual sand and machining debris from passages. Record any agreed repair restrictions before production. Continuous-cast stock may be considered for machined blanks when expressly ordered, but it is a different product form from the shaped casting routes listed above.
Quality standards and certification requirements
| Reference / evidence | How it applies |
|---|---|
| ASTM B584 | General copper-alloy sand casting requirements; check grade scope |
| ASTM B271/B271M | Centrifugal casting requirements for applicable copper alloys |
| ASTM B505/B505M | Continuous-cast material when that product form is ordered |
| ASTM B763/B763M | Sand castings for valve applications, subject to grade and scope |
| ASTM B62 | Composition bronze / ounce metal requirements relevant to C83600 enquiries |
| ASTM B30 | Ingot and remelt material requirements; not a finished-part certificate |
| ASTM B806 / EN 1982 | Review permanent-mold or European casting requirements as applicable |
| Inspection documents | Agree chemical, dimensional, mechanical, pressure or NDT reports |
Standards describe requirements; they do not prove that a supplier holds a particular certification. State any required quality-system certificate, independent inspection or project approval in the enquiry. Certification scope and current documents must be confirmed before making an acceptance decision. These leaded alloys should not be represented as lead-free or automatically compliant with every end-use restriction. Tests, sampling and acceptance criteria should match the actual C83800 component and order.

Frequently asked questions
What does this product range include?
C83800 Bronze Casting and Machined Cast Components covers drawing-based supply of hydraulic component bodies, machined adapters, pump fittings and general hardware. Buyers can specify cast blanks or finished machining. The quotation should identify the alloy, manufacturing route, dimensions and acceptance requirements so that the supplied part matches the intended assembly.
How should I specify the alloy?
C83800 should appear with the applicable product standard and drawing revision. CDA 838 / hydraulic bronze; No direct EN/BS match asserted; Do not substitute C83810. Trade names and international comparison grades do not remove the need to verify chemistry, mechanical requirements and product form.
Which casting processes can be considered?
Investment casting, green sand casting, permanent mold casting, shell molding (resin sand), centrifugal castings and gravity die casting (GDC) can be evaluated. GDC is a form of permanent-mold casting. Suitability depends on alloy, geometry, quantity and required soundness; not every process is offered for every part.
Can the parts be supplied fully machined?
Yes, enquiries can include turning, boring, milling, drilling, threading and specified groove machining. Provide datums, final tolerances, surface finish and the condition in which dimensions are measured. The agreed quotation defines the actual machining operations, inspection coverage and any features left as-cast.
What is the price per kilogram?
The listed rate is US$ 17.90/kg. Confirm the weight basis and whether tooling, machining, testing, packing, freight and taxes are included in the quotation. An approved drawing and quantity allow the commercial scope to be matched to the component instead of comparing rates for different supply conditions.
Are international grades directly interchangeable?
Some designations identify the same alloy family, while others are only approximate comparisons. Different limits for tin, lead, zinc or residual elements can prevent dual compliance. Check the full standards, casting route and required properties, and obtain design approval before replacing the material specified on an existing drawing.
Are leaded bronze parts suitable for every water or electrical application?
No. Lead content and end-use restrictions must be considered for the intended market and equipment. A leaded alloy is not automatically suitable for drinking-water service. Current-carrying parts also require electrical assessment; a bronze material certificate alone does not establish contact resistance, temperature rise or an assembly rating.
What inspection documents can be requested?
An order can specify heat-linked chemical analysis, dimensional reports and agreed mechanical or non-destructive examinations. Pressure tests and microstructure checks should be defined where relevant. Establish sampling, acceptance criteria and witness requirements before production so that the necessary test pieces and manufacturing hold points can be planned.
What information is needed for a quotation?
Send the drawing revision, C83800 requirement, quantity, estimated weight, casting and machining scope, service conditions and delivery destination. Include mandatory testing, marking and packaging requirements. For replacement parts, identify which dimensions come from an approved drawing and which were measured from a worn sample.
