Translate function into requirements
Begin with strength, weight, wear, temperature, corrosion, conductivity and regulatory constraints rather than selecting a familiar alloy by default.
Check manufacturing implications
Machinability, stock availability, heat treatment, distortion risk and finish compatibility affect both cost and achievable geometry. Confirm the exact grade, temper or condition.
Common material groups
- Aluminum alloys for low weight and general machinability
- Carbon and alloy steels for strength, wear and heat-treatment options
- Stainless steels for corrosion resistance with grade-specific machining behavior
- Brass and copper alloys for conductivity, appearance or machinability
- Engineering plastics for insulation, low friction or weight reduction
Final selection should be validated against the part application and drawing.
