As the third generation of armor alloy developed by USA in the 1980s, 2519 aluminum alloy has some advantages such as light-mass, high strength as well as high corrosion resistance. Up to today, most work... is less than 6.0%, the strength of 2519 aluminum alloy increases with the increase of Cu content; when the content of Cu is more than 6.0%, the strength of the alloy decreases. The hardening effect......
