Aluminum Alloy 7075

The alloys are classified and named according to the amount and type of the alloying metals . Given widespread applications across industries, selecting the right aluminum alloy type for a specific end-use is crucial. Just slight differences in chemical properties can drastically alter strength, workability, corrosion resistance, and electrical conductivity of the alloy.

Aluminum alloy  7075 is a heat-treatable aluminum alloy with zinc as the primary alloying element. It has moderated formability when in the fully soft, annealed temper and can be heat-treated to strength levels that are comparable to many steel alloys.

 7075 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, resistance welding is preferred, while gas and arc welding should be avoided.
