1. Start with the application

Describe where the component operates, its loads, temperature and environment, and whether leak tightness, corrosion resistance or impact performance is required.

2. Match material, geometry and process

Wall thickness, flow length, section changes and component mass affect casting feasibility. Quantity, available patterns or samples and the intended casting route also matter.

3. Define the delivered condition

Identify machined surfaces, tolerances and any requirements for welding, heat treatment, surface protection or inspection. The required delivery condition should appear on the drawing or specification.

Information for an enquiry

Provide the full documentation and the grade stated on the drawing whenever available. If the material has not yet been defined, provide operating criteria rather than selecting a grade from a generic table alone.

• 2D drawing or 3D model and component mass
• function, loads, temperature and environment
• quantity and required timing
• machined surfaces and tolerances
• inspection, quality documents and required standard edition

Standards reference

ISO 3522:2007 covers the chemical composition and mechanical properties of aluminium alloy castings. The ISO catalogue shows it as confirmed in 2025 and due for revision, so the order should state the required edition and full material designation.

Final selection should reflect design documentation, the casting process and finished-component requirements.
