DIN 1725-1 Grade 3.4365 T73 – High‑Strength 7075 Aluminum Alloy
DIN 3.4365 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.
