The 7150 Aluminum Block plate is a perfect Al-Zn-Mg-Cu plus Zr high alloy 7000 series alloy. It is a modified alloy developed on the basis of the optimization of the 7050 main alloy composition. The composition of the main alloy elements is adjusted and the Fe, 7150 The main application of the alloy is the pre-stretched thick plate in the T7751 state, which improves the quality and anti-stripping ability of the alloy. It has the characteristics of high strength and infiltration hardenability. And T77511 extrusion.
