The 7075 aluminum plate is an important aircraft aluminium sheet. It is an aluminum-magnesium-zinc-copper alloy and a heat-treatable alloy. It is a super hard aluminum alloy and has good wear resistance. After further processing, it doesn’t have deformation.
Of this alloy, the 7075 T6 aluminum plate is a top grade and it is known as the best product among aluminum alloys with high strength. This alloy also has good mechanical properties and anodizing reaction.
Zinc is the main alloying element in 7075 aluminum sheet. Adding magnesium to the 7075 aluminum alloy containing 3%-7.5% zinc can form MgZn2 with a significant strengthening effect, making the alloy's heat treatment effect far better than aluminum-zinc aluminum alloys. 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.
The 7075 aluminum plate is mainly used to manufacture aircraft structures and other high-stress structural parts that require high strength and corrosion resistance, such as aircraft upper and lower wing panels, stringers, etc. It is also widely used in mold processing, mechanical equipment, phone shell,etc.
After solution treatment, 7075 aluminium sheet has good plasticity and good heat treatment strengthening effect. It also has good strength below 150 degrees, and has particularly good low temperature strength, poor welding performance, and stress corrosion cracking tendency.
As a big 7075 aluminium plate supplier, Haomei 7075 aluminum plate has internal stress relief and no deformation when cutting. The maximum width is 2600mm and the maximum thickness is 200mm.
All of our 7075 aluminum plate is rolled by the ultra-wide 2650mm German SMS cold rolling mill, which has better shape, higher precision and more stable performance. All the super wide 7075 aluminum alloy plates produced by Haomei are ultrasonically detected, which can effectively ensure that there are no blisters and impurities.
