Forming 7075 Aluminum Sheet

In this post we ll explain it to you.

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. Aluminum sheet plate 7075 is normally used for aerospace military and automotive applications. If forming difficulty is encountered in the annealed condition then warming the material to 200 250 f will assist formability. 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.

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. In high purity forms aluminum is soft and ductile. The mechanical properties of 7075 depend greatly on the tempering of the material. 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. 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. The available sizes for the 7075 aluminum plate are between 25 and 8 inches thick 48 5 and 60 5 inches wide and up. 7075 aluminum is an aluminum zinc alloy with 1 8 zinc in addition to small amounts of magnesium and small quantities of copper and chromium.

Its use parallels that of 2024 with 7075 selected when higher mechanical properties are desired. 7075 is comparatively tough for an aluminum alloy. 7075 is the strongest aluminum with the strength of many steels while retaining aluminum s lightweight qualities and corrosion resistance. 7075 aluminum sheet plate stock is available in full size and custom cut lengths.

As such it produces greater springback during forming operations. 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.

This alloy is precipitation hardened to very high. We offer waterjet services for this product. As with alloy 2024 alloy 7075 is available in bare form or in clad alclad to offer even further protection from corrosion.
