What Are 7050 Aluminum Plate
Sep 01, 2018

7050 aluminum sheet is a high-strength heat treatable alloy with extremely high strength and resistance to spalling and stress corrosion cracking. Commonly used in aircraft structural parts for medium and heavy plate extrusions, free forgings and die forgings. The requirements for the manufacture of such parts are: resistance to flaking corrosion and stress corrosion cracking, fracture toughness and fatigue resistance.


The main alloying element of 7075 series aluminum alloy is zinc. Adding magnesium to the alloy containing 3%-75% zinc can form MgZn2 with remarkable strengthening effect, which makes the heat treatment effect of the alloy far better than aluminum-zinc binary alloy. The content of zinc and magnesium in the tensile strength will be further improved, but its ability to resist stress corrosion and flaking corrosion will decrease. After heat treatment, it can achieve very high strength characteristics. Consulted with copper and other alloys. The system is made of 7075-T651 aluminum alloy, which is known as the best product in aluminum alloy. It has high strength and is far better than mild steel. This alloy has good mechanical properties and anode reaction. Used in aerospace, mold processing, mechanical equipment, fixtures, especially for aircraft manufacturing structures and other high-stress structures with high strength and corrosion resistance.
