Quote the component, not just the alloy
Aluminum CNC machining covers parts with different alloys, geometries and acceptance requirements. The material grade and condition should match the approved drawing. This page focuses on the part request; the material library covers grade information.
See the aluminum material overview, including the 6061-T6/T651 detail when that is the specified stock. For the service overview, see CNC milling.
Show the requirements that control the finished part
- Material designation, temper and drawing revision.
- Datums, mating surfaces, holes and critical dimensions.
- Finish, masking and dimensions inspected after treatment.
- Quantity, inspection records and delivery destination.
Do not infer tolerance or surface acceptance from the material name. Define them on the drawing and state whether they apply before or after any secondary process.
