7A09 aluminium flat bar plate

The plasticity of 7A09 aluminium flat bar plate in the annealed and freshly quenched state is slightly lower than 2Y12 in the same state, and slightly better than 7A04. After quenching and artificial aging, the plasticity is significantly reduced. The static fatigue, notch sensitivity, and stress corrosion properties of the alloy sheet are slightly better than 7A04, and the bar is equivalent to 7A04.
 
Main components of 7A09 aluminium flat bar plate (%) Cu: 0.1; Si: 0.25; Fe: 0.4; Mn: 0.1; Mg: 2.2-2.8; Zn: 0.1; Cr: 0.15-0.35; Ti: /; Al: balance The main alloying element of 5052 steel is magnesium, which has good forming performance, corrosion resistance, weldability, and medium strength. It is used to manufacture aircraft fuel tanks, oil pipes, and sheet metal parts for transportation vehicles and ships, meters, street lamp brackets, and Rivets, hardware products, electrical enclosures, etc.
