Aluminum grade & manufacturing route

Separate Wrought Grades from Casting Alloys

Select the exact alloy and condition for the intended route. A wrought grade and a casting alloy are separate material specifications, even when the final components have similar shapes.

Aluminum Selection Notes

Selection context

Aluminum offers low density and a range of strength, thermal and finishing properties that depend on alloy and condition. Wrought grades for CNC machining and die-casting alloys have different composition and processing requirements.

Common options

6061 and 6082 are common wrought grades for machined components. 2024 and 7075 may be considered for higher-strength applications when the temper and service environment are suitable. A380, A360, ADC12 and AlSi9Cu3 are casting-alloy references. Confirm the governing specification, product form and material condition for each grade.

RFQ Requirements

Review alloy and temper, load direction, corrosion exposure, joining, anodizing or coating, cosmetic expectation, dimensional stability, and material certification. The Aluminum Association publishes authoritative alloy designation and property references.

Reference basis: The Aluminum Association standards.

Common questions

Material Selection Questions

Are wrought and die-casting aluminum grades interchangeable?

No. Grades such as 6061 and 7075 are wrought references, while A380, ADC12, and similar designations refer to casting routes with different specifications and behavior.

Who approves the final material specification?

The customer approves the grade, material condition, governing specification, required material records and permitted substitutions before production release.

Can finishing change the material decision?

Yes. Review coating compatibility, appearance, thickness, masking, heat exposure and electrical or corrosion requirements alongside the base material.
