Copper alloy die casting based on the exact grade, component function and process requirements, including tooling, machining and inspection.
Review the component, material specification and delivery requirements together before selecting tooling and production conditions.
Copper alloy weight, wall thickness and tolerances are confirmed for the exact grade, geometry and production configuration. Aluminum and zinc ranges or general equipment counts do not establish copper alloy capacity.
Pure copper, brass and bronze have different properties and processing requirements. Start with the exact material specification and the function of the finished part.
Assess the specified grade, filling and local geometry, tooling requirements, production quantities and secondary machining. Confirm the process configuration and acceptance criteria before committing to production.
Review die tooling requirements →Evaluate the grade and material state, stock form, tool access, workholding, finish and quantities. Compare the complete manufacturing route where functional, design-change or economic requirements favor machining.
Explore copper alloy CNC machining →Provide the exact grade, batch and annual quantities, design stability, critical features and functional requirements so the options can be compared on the same basis.
Compare casting alloy families →Use the drawing to identify which features locate, connect or contact other components, and which require secondary machining or controlled surface treatment.
A flanged sleeve illustration provides context for geometry review. Its exact grade, manufacturing route and wear performance are not established by the image.
Plan the material, critical interfaces and production economics around the requirements of the delivered component.
Define conductivity, heat transfer, wear, loads, temperature and exposure media for the selected grade. Agree functional tests and acceptance records.
Review inspection & documentation →Identify holes, mating faces, joining interfaces and functional contact areas. Define masking and acceptance before or after surface treatment.
Review secondary CNC machining →Compare quantity, tooling investment, maintenance, replaceable features, machining and finish costs for the complete delivered component.
Plan tooling & trial requirements →Material reference values support initial selection. Confirm the specified grade, manufacturing condition and acceptance criteria for the finished component.
Select the copper alloy for the required conductivity, wear behavior, mechanical properties and operating environment. C85800 cast brass is the reference grade used here. Pure copper, other brasses and bronzes have different properties and processing requirements; compare alternative manufacturing routes where appropriate.

The following published values refer to C85800 cast brass. Use these values for initial material comparison. Part acceptance and design properties require the applicable specification, delivery condition and representative test evidence.
| Reference property | Value |
|---|---|
| Density | 8.44 g/cm³ |
| Typical tensile strength | Approx. 379 MPa |
| Reference Brinell hardness | Not listed in the cited database |
| Approximate melting range | 871–899°C |
Copper Development Association C85800 data. Mechanical data refers to pressure-die-cast condition M04. The approximate 379 MPa tensile value is converted from 55 ksi; the melting interval is converted from the source solidus and liquidus temperatures. No Brinell hardness is inferred from another hardness scale.
The melting range describes the solidus-to-liquidus interval. Service limits and casting temperatures must be established separately.
Specify conductivity, heat-transfer requirements, wear conditions, loads and corrosion exposure for the selected grade. Cast brass has different conductivity and mechanical properties from pure copper. Service-temperature suitability depends on alloy, delivery condition, loading and exposure duration.
Review filling, thermal loading, local geometry, casting quality and secondary machining with the selected alloy and equipment configuration. Establish casting temperatures and tooling requirements for that process. The listed C85800 melting interval is a material property, not an operating setpoint.
Thermal loading makes die material, heat treatment, insert design and maintenance important to tooling performance and cost. Define the steel specification, heat-treatment requirements, replaceable features and criteria for continued use in the tooling agreement.
Published die-life reference: 5,000–50,000 shots, from the Uddeholm tooling guide, page 12. The range counts casting cycles. Confirm actual tool life and core or insert replacement intervals for the project; the reference is not a service-life commitment.
Copper alloys vary substantially in machining behavior. The CDA database lists a relative machinability rating of 80 for C85800; cutting parameters still require selection for the tool, operation and material condition. Polishing, chemical coloring, plating or painting may be evaluated against the substrate and preparation requirements. Specify coating adhesion, appearance and functional contact areas.
Agree finish samples, coating thickness, adhesion, corrosion-test conditions and whether dimensions apply before or after treatment. Electrical or thermal contact areas may need defined masking and interface requirements.
Account for component mass, material utilization, tooling wear and secondary operations at the expected production volume. Compare the specified grade with alternatives using quotations for the same date, quantities and delivery terms.
Compare cost per accepted component, including material utilization and recovery, tooling, production, secondary operations, inspection, rejects, packaging and transport. Energy use also depends on furnace efficiency, holding time and production utilization.
Confirm alloy, size, mass, tolerances, finish and testing requirements during the drawing and DFM review. Record the agreed manufacturing and acceptance requirements before production release.
Specify the exact grade and governing material requirements. C85800 cast brass is one reference; pure copper, other brasses and bronzes require separate process and property review.
Define the grade, delivery condition, required properties, test method and specimen source. The C85800 reference tensile value of approximately 379 MPa applies to the cited pressure-die-cast condition.
Review the exact grade, condition, chip formation, tool wear, geometry and surface requirements. Published relative ratings support comparison but do not define cutting parameters.
Review each exact grade and delivery condition separately. C85800 cast brass is the reference on this page; its properties and pressure-die-cast condition do not establish suitability for pure copper or every brass and bronze grade.
Compare the grade and stock form, geometry, expected quantities, design stability, tool investment, machining access and finish requirements. Review the cost and acceptance requirements of the complete delivered part before selecting a route.
Specify the required performance, operating temperature, loads, exposure conditions and mating materials. Identify the test method, acceptance criteria and required records. A copper-alloy family name alone does not define these requirements.
