The 7018 alloy is a Al-Zn-Mg-Mn based alloy. Its components are 0.35 Si, 0.45 Fe, 0.20 Cu, 0.15~0.50 Mn, 0.7~1.5 Mg, 0.20 Cr, 0.10 Ni, 4.5~5.5 Zn, 0.15, Fe, and other impurities, 0.05 0.05, 0.15, and the rest is a. It is a British alloy, registered in the American Aluminum Association in 1978 and used in the state of T5 or T6, with considerable strength and good weldability. The lowest mechanical properties of Forgings: tensile strength and yield strength of Rm410N/mm - Rp - 360N/mm., elongation of A 10%, Bush HBW. / hardness 115. The automobile industry uses it to forge forgings with both high strength and good weldability.
