Input data
Drawing, pattern or sample, alloy grade, quantity and component requirements.
The terms “aluminium” and “silumin” cover many alloys. Send the complete material designation stated on the drawing or in the specification.
ISO 3522 covers composition and mechanical properties of separately cast test bars for aluminium casting alloys, but it does not replace the requirements specified for a particular component.
Send a drawing or 3D model and specify the aluminium alloy grade if it has been selected. State whether a foundry pattern, permanent mould or sample component is available.
If the grade or tooling has not yet been established, state this in your message. Email the documentation to biuro@metalkolor.pl. Do you need a pattern for your casting? Explore our foundry pattern making services and the information needed for a tooling enquiry.

The scope may cover an as-cast component or machining of specified surfaces. Allowances, tolerances and acceptance requirements must follow the agreed documentation.
We do not identify a grade from a photograph alone. If the designation is missing, describe the application and operating conditions.
ENQUIRY PATH
Each stage follows the component documentation.
Drawing, pattern or sample, alloy grade, quantity and component requirements.
Delivery condition, surfaces to be machined and acceptance criteria.
Casting and agreed operations performed to the order documentation.
FAQ
Answers to the most common questions about the initial information.
No. Aluminium-silicon alloys form a broad group. Include the full grade from the drawing or specification.
Yes, when the scope is defined in the documentation. Identify the surfaces, dimensions and acceptance requirements.
Send a drawing or sample and state that no pattern is available. The possible preparation scope can then be reviewed.
No. Visual appearance does not replace a material designation or technical documentation.

See the information needed to assess sand or gravity die casting.
We produce gravity castings in sand moulds. The process, material and subsequent machining scope are agreed from the component geometry, documentation and order requirements.
Gravity die castingWe produce gravity die castings, including aluminium alloy castings. The use of permanent metal tooling is confirmed after reviewing the alloy, geometry, quantity and component requirements.
