forged 7075 aluminum has a compact structure and strong corrosion resistance. It is best for aviation and marine plates. Ordinary corrosion resistance, good mechanical properties and anode reaction. Smaller sizes have better depth and depth performance and enhanced tool wear resistance.
The main alloying element in forged 7075 aluminum is zinc. Adding magnesium to an alloy containing 3%-7.5% zinc can form MgZn2 with a significant strengthening effect, making the alloy's heat treatment effect far better than excessive aluminum-zinc Binary alloy. Increasing the content of zinc and magnesium in the alloy will further improve the tensile strength, but its resistance to stress corrosion and spalling corrosion will decrease. Through heat treatment, very high strength characteristics can be achieved.
Mechanical properties of forged 7075 aluminum
