Component identification
Drawing or sample, full grade, quantity and application.

Brass castings
For brass castings, use the dedicated service page to check the information needed for an initial review and contact the team about your component.
If the material family is uncertain, use the designation from the documentation instead of guessing from colour.

We produce bronze castings to agreed customer documentation. Process selection and machining scope begin with the full alloy designation, component geometry and required delivery condition.
Bronze castings made to customer documentationOne material group, many grades
Copper, bronzes and brasses form a broad material group with different compositions and properties. A family name does not replace the exact grade from the drawing.
Include the full material designation in your enquiry. If it is missing or illegible, state this and describe the application and operating conditions.
Documentation for copper and copper alloy castings
Provide the full material designation from the drawing or specification. If it has not been established, describe the component’s application and operating conditions.
For a feasibility review, include a drawing or 3D model, the quantity, details of available tooling, the required delivery condition and the machining scope. Add mechanical, leak-tightness or acceptance requirements where they are specified in the documentation. Do you need a pattern for your casting? Explore our foundry pattern making services and the information needed for a tooling enquiry.
Email the documentation to biuro@metalkolor.pl. Separate bronze and brass pages help you choose the relevant service.
As-cast condition and subsequent machining
Before production, we agree whether an as-cast component is required or whether specified surfaces should also be machined. Finished-part requirements should come from the documentation.
Include dimensions, quantity, information about machining allowances and tolerances, and acceptance criteria if these have been defined.
Images from METAL-KOLOR
The photographs show components from the historical copper alloy casting gallery. They do not confirm the grade or parameters of a particular order.

FAQ
Before you send an enquiry
Answers to the most common questions about the initial information.
Are bronze and brass the same material?
No. They are different copper alloy families. Include the exact grade from the documentation in your enquiry.
Can the alloy be identified from the colour in a photograph?
No. Colour also depends on the surface, lighting and processing. The grade must come from documentation or testing.
Can the casting be supplied with machining?
The scope may include machining of specified surfaces when the requirements are agreed from the drawing.
How should I describe a one-off component or a series?
State the quantity, material, dimensions, available pattern or sample, delivery condition and acceptance requirements.
