7075 Machining

A Guide to aluminium 7075 CNC Machined Parts: Properties, Applications and Design Considerations

What is 7075?7075 Aluminium Machined Part

Aluminium 7075 was developed by a Japanese manufacturer in the 1930s, looking to build lighter aircraft. 

Today 7075 bar and plate is a commonly used commercial grade of very high strength aluminium that has zinc as the primary alloying element (as with all alloys in the 7000 series). L95 is the aerospace approved equivalent.

7075 applications include high strength components where corrosion resistance is less important.

L95 applications include aerospace, nuclear and military highly stressed structural components.

Main Attributes of 7075 / L95:

  • Very high strength aluminium alloy (comparable to many steels)
  • Good fatigue strength
  • Increased strength at sub-zero temperatures
  • Reduced strength at very high temperatures
  • Less resistance to corrosion than many other aluminium alloys
  • Some tempers offer improved stress-corrosion cracking resistance
  • One of the highest strength to weight ratios of any aluminium alloy
  • Generally speaking does not offer good weldability
  • Heat treatable
  • Can be highly polished
  • Poor formability/workability
  • Attributes do vary by temper, for example:
