7072 H111 O aluminum coil strip

7072 H111 O aluminum coil strip belongs to the 7××× series of alloy aluminum coils: on behalf of 7075. Mainly contains zinc. It also belongs to the aviation series. It is an aluminum-magnesium-zinc-copper alloy, a heat-treatable alloy, and is a super hard aluminum alloy with good wear resistance. 7072 H111 O aluminum coil strip is stress-relieved and will not deform or warp after processing. All the super-large and super-thick 7072 H111 O aluminum coil strips are all ultrasonically detected, which can ensure that they are free of blisters and impurities. The 7072 H111 O aluminum coil strip has high thermal conductivity, which can shorten the molding time and improve work efficiency. The main feature is that the hardness 7072 is a high-hardness, high-strength aluminum alloy, which is often used to make airplanes.
 
7072 H111 O aluminum coil strip characteristics and scope of application: high-strength alloy. The plasticity in the annealed and as-quenched state is slightly lower than 2Y12 in the same state, and slightly better than 7A04. After quenching and artificial aging, the plasticity is significantly reduced. The static fatigue, notch sensitivity, and stress corrosion properties of the alloy sheet are slightly better than 7A04, which is equivalent to 7A04
