1. Ingredient difference:
ال 6061 aluminum alloy consists of 97.9 percent aluminum, 1 المغنيسيوم في المئة, و 0.6 percent silicon, مع 0.28 percent copper and 0.2 percent chromium added.
The composition of the 7075 aluminum alloy roughly includes 5.6-6.1%, 2.1-2.5% zinc, المغنيسيوم 1.2-1.6% copper, less than half a percent, silicon, حديد, manganese, titanium, chromium, and other metals. It usually produces several grades of hot temper, 7075-يا, 7075-T6, and 7075-T651.
