7075 and 7A04 materials are off-limits in the foundry industry. At present, there has been no breakthrough in the global aluminum alloy foundry industry. At present, Weizhen Squeeze casting has solved the density of 7075 casting production above 2.8, and there are no sand holes in some parts. Thousands of tests of heat treatment eventually push 7075 castings to the level of physical forging.
