T73 vs T651: Understanding the Difference
The T73 temper involves a two-stage overaging heat treatment that slightly reduces peak strength but dramatically improves resistance to stress corrosion cracking. For aerospace structural applications exposed to corrosive environments or sustained stress, T73 is the recommended temper over T651.
Frequently Asked Questions
Q: What is the advantage of T73 over T6/T651?
A: T73 provides significantly better resistance to stress corrosion cracking while retaining most of the strength of T6 temper.
Q: Is 7075 T73 suitable for aerospace use?
A: Yes, 7075 T73 is widely specified for aerospace structural components requiring both high strength and corrosion reliability.
Q: Can 7075 T73 be anodized?
