6061 Machined Parts
A Guide to aluminium 6061 CNC Milled & Turned Parts: Properties, Applications and Design Considerations
What is 6061?
6061 is a versatile medium to high strength heat-treatable American wrought aluminium alloy.
Aluminium 6061 is primarily composed of aluminium, magnesium and silicon.
The most common temper is T6. See further heat treatments/temper states below.
Please note: the UK equivalent of 6061 is 6082. 6082 is comparatively new, has replaced 6061 in many applications and is recommended for use by Penta Precision. Please see our 6082 materials page for further information.
Main Attributes of Aluminium 6061:
- Excellent corrosion resistance to atmospheric conditions & good resistance to sea water
- Very good weldability although reduced strength in weld zone (can be re-heat treated & artificially aged again to restore strength)
- Medium fatigue strength
- Available in sheet, plate & extrusions
- Good surface finish
- Good toughness and structural strength
- Good machinability
