Forming 7075 Aluminum Sheet

It can be formed in the annealed condition and subsequently heat treated.

Forming 7075 aluminum sheet.

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. The available sizes for the 7075 aluminum plate are between 25 and 8 inches thick 48 5 and 60 5 inches wide and up. This alloy is precipitation hardened to very high. The mechanical properties of 7075 depend greatly on the tempering of the material.

7075 aluminum sheet plate stock is available in full size and custom cut lengths. 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. 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.

Corrosion resistance and machinability are rated as fair though the addition of chromium provides good stress corrosion cracking resistance in 7075 aluminum sheet products. In high purity forms aluminum is soft and ductile. Aluminium 7075a has a density of 2 810 g cm 0 1015 lb in. In this post we ll explain it to you.

Aluminum sheet plate 7075 is normally used for aerospace military and automotive applications. Afterwards solution heat treatment should be used. As such it produces greater springback during forming operations. The weldability of this metal is low but the formability is great.

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

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. If forming difficulty is encountered in the annealed condition then warming the material to 200 250 f will assist formability. When forging is used it s required that the alloy be placed in temperatures between 700 and 900 degrees f.
