Balasen supplies custom copper alloy castings, including selected brass and bronze components, according to customer drawings and material specifications. Casting process, alloy grade, machining and inspection requirements are evaluated according to component size, geometry, operating conditions and required mechanical properties.
For furan resin sand casting, Balasen’s published copper casting capacity covers individual component weights from 50 to 5,000 kg. The published lead time for copper casting blanks is generally 30 to 45 days. Final feasibility, alloy composition, casting weight and delivery schedule are confirmed after drawing and specification review.
The performance of a copper casting depends on the selected alloy rather than copper content alone. Brass, tin bronze, aluminum bronze, nickel-aluminum bronze and copper-nickel alloys provide different combinations of strength, wear resistance, corrosion resistance, machinability and conductivity.
Balasen evaluates the alloy grade according to the customer’s drawing, mechanical load, operating temperature, service medium and required inspection criteria. Pure copper projects require separate technical review because their melting control, casting behavior and conductivity requirements differ from those of conventional brass and bronze castings.
Selected copper alloys may be considered for marine, pump and valve components where corrosion resistance, mechanical strength, wear performance or resistance to fluid erosion is required. Aluminum bronze, nickel-aluminum bronze and copper-nickel alloys are commonly evaluated for demanding fluid-service environments.
Material suitability depends on the service medium, chloride concentration, operating temperature, flow conditions, mechanical load and compatibility with mating materials. The exact alloy, casting process, heat treatment, machining and inspection requirements must therefore be confirmed for each project.

Most industrial copper castings are produced from copper-base alloys rather than pure copper. The appropriate alloy should be selected according to corrosion conditions, mechanical load, friction, wear, conductivity and the customer’s material specification.
Copper-zinc alloy castings can be evaluated for components requiring a balance of corrosion resistance, machinability and mechanical performance. Exact composition, lead content and regulatory requirements must be confirmed from the specified grade.
Tin bronze and selected leaded bronze alloys may be reviewed for bearings, bushings, wear components and other applications involving sliding contact. Material selection must consider strength, wear conditions, lubrication and applicable restrictions on lead-containing alloys.
Aluminum bronze castings can be evaluated for projects requiring increased strength, wear resistance or corrosion performance. The selected UNS grade, heat-treatment condition and mechanical requirements must be confirmed for each order.
Nickel-aluminum bronze and copper-nickel alloys may be considered for marine, pump, valve and other corrosive-service projects. Actual alloy availability, melting control, heat treatment and inspection requirements must be verified before quotation.
Pure copper and customer-specific copper compositions require separate technical review because conductivity requirements, oxidation control, casting behavior and acceptance criteria may differ significantly from conventional brass or bronze castings.
Applicable standards should be selected according to the alloy, casting process and component application. Listing a standard does not mean that every Balasen copper casting automatically complies with every grade or supplementary requirement within that standard.
| Standard | Standard Scope | Project Confirmation |
|---|---|---|
| ASTM B584 | Copper alloy sand castings for general applications. | UNS grade, chemical composition, mechanical properties and current standard revision. |
| ASTM B148 | Aluminum-bronze sand castings. | Required UNS alloy, heat treatment, mechanical properties and inspection. |
| ASTM B763/B763M | Copper alloy sand castings for valve applications. | Valve application, specified alloy, test bars, hardness and acceptance criteria. |
| ASTM B61 and ASTM B62 | Steam or valve bronze castings and composition bronze castings. | Grade availability, service medium, pressure-related requirements and material restrictions. |
| ASTM B369/B369M | Copper-nickel alloy castings. | Alloy availability, corrosion environment, mechanical properties and inspection requirements. |
| ASTM B824 | General requirements supporting copper alloy casting specifications; it is not a standalone alloy grade. | Applicable product specification and customer purchase requirements. |
Casting process selection is based on component size, alloy behavior, geometry, wall thickness, production quantity and required surface or dimensional condition. One process should not be presented as suitable for every copper alloy casting.
Furan resin sand casting is Balasen’s published process for medium and large copper alloy components weighing from 50 to 5,000 kg. Final process design depends on alloy type, wall thickness, feeding requirements and component geometry.
Green sand casting may be evaluated for suitable copper alloy components and production quantities. Actual alloy compatibility, weight range, tooling requirements and achievable casting condition must be confirmed before quotation.
Lost foam casting can be considered when the component geometry and copper alloy are suitable for the process. Process feasibility, minimum wall thickness, dimensional expectations and inspection requirements must be reviewed from the drawing.
The following component categories can be evaluated according to customer drawings. They should only be described as completed Balasen projects after production records or original factory photographs have been verified.
| Part Category | Technical Considerations | Required Review |
|---|---|---|
| Pump and Valve Components | Valve bodies, pump components and flow-control parts may require corrosion resistance, controlled internal passages, machining and project-specific inspection. | Service medium, material standard, pressure-related requirements and finished dimensions. |
| Bushings and Bearings | Sliding contact, lubrication, wear resistance, bore dimensions, machining allowance and material compatibility. | Load, speed, lubrication condition, mating material and required alloy. |
| Gears and Worm Wheels | Tooth machining allowance, wear conditions, strength, casting soundness and final dimensional control. | Torque, speed, tooth geometry, mating material and heat-treatment requirements. |
| Marine and Corrosion-Resistant Parts | Alloy selection, seawater or chemical exposure, corrosion allowance, surface condition and inspection requirements. | Fluid composition, temperature, flow conditions, material grade and design life. |
| Custom Industrial Components | Non-standard housings, wear components, support parts and other copper alloy castings produced according to customer drawings. | Drawing, alloy, annual quantity, tolerance, inspection and application details. |
Machining and inspection requirements are established according to the drawing, alloy, casting condition and intended application. Copper alloys can differ significantly in machinability, hardness and dimensional behavior, so final processing requirements must be reviewed for each component.
