Forming 7075 Aluminum Sheet

7075 is comparatively tough for an aluminum alloy.

Forming 7075 aluminum sheet.

Corrosion resistance and machinability are rated as fair though the addition of chromium provides good stress corrosion cracking resistance in 7075 aluminum sheet products. It can be formed in the annealed condition and subsequently heat treated. When forging is used it s required that the alloy be placed in temperatures between 700 and 900 degrees f. We offer waterjet services for this product.

This alloy is precipitation hardened to very high. 7075 aluminum sheet plate stock is available in full size and custom cut lengths. The weldability of this metal is low but the formability is great. Which aluminum alloy bends the best is a a common question customers want the answer to.

With zinc as the dominant alloying element the 7075 aluminium alloy also known as aircraft aluminium or aerospace aluminium was the first alloy of high strength composed by al zn mg cu that was able to successfully combine the perks of the inclusion of chromium to develop high stress corrosion cracking resistance in sheet products. 7075 t651 aluminum plate this aluminum plate is made of one of the strongest of the aluminum alloys. In this post we ll explain it to you. Un heat treated 7075 7075 0 temper has a maximum tensile strength of no more than 280 mpa 40 000 psi and maximum yield strength of no more than 140 mpa 21 000 psi.

Afterwards solution heat treatment should be used. Aluminium 7075a has a density of 2 810 g cm 0 1015 lb in. The mechanical properties of 7075 depend greatly on the tempering of the material. The available sizes for the 7075 aluminum plate are between 25 and 8 inches thick 48 5 and 60 5 inches wide and up.

In high purity forms aluminum is soft and ductile. Warm forming technology is a promising approach to improve the formability of peak aged 7075 aluminum alloys aa7075 t6 5 6 7 8 where the aa7075 t6 blank is heated to target temperatures. Aluminum sheet plate 7075 is normally used for aerospace military and automotive applications. As such it produces greater springback during forming operations.

Bending is a delicate and demanding process most of the time and common fabricating processes require a degree of formability that make your choice of proper alloy critical. 7075 is the strongest aluminum with the strength of many steels while retaining aluminum s lightweight qualities and corrosion resistance. If forming difficulty is encountered in the annealed condition then warming the material to 200 250 f will assist formability.
