Aluminum 7075 is a high-strength alloy that offers good stress-corrosion cracking resistance. Known as a mainstay in the aerospace industry since it was introduced, Aluminum 7075 brings moderate toughness as well as an excellent strength-to-weight ratio. It is also important to note that at sub-zero temperatures Aluminum 7075 increases in strength.
When it comes to welding, the resistance welding is preferred, while gas and arc welding should be avoided. It is available in in the clad (Alclad) form to improve corrosion resistance.
Due to these outstanding benefits, Aluminum 7075 is used extensively for a number of applications including:
- Highly stressed structural parts
- Aircraft fittings
- Gears and shafts
- Fuse parts
- Meter shafts and gears
- Missile components
- Regulating valve parts
- Worm gears
- Other aerospace and aircraft parts
The unique chemical composition of Aluminum 7075 includes:
- Al balance
- Zn 5.1-6.1%
- Mg 2.1-2.9%
- Cu 1.2-2.0%
- Mn 0.30%
- Fe 0.50%
- Si 0.40%
- Ti 0.20%
- Cr 0.18-0.28%
