Is 7075 aluminum stronger than steel? - Keganhirl - 11-25-2021
7075 is able to match most steel alloys in terms of strength. ... As for its detailed characteristics, 7075 Aluminum (T651) features a tensile strength of 83,000 psi, with a yield point of 74,000 psi. The Brinell hardness is rated at 150, with the elongation at break being 10%. It offers a shear strength of 48,000 psi.
When it comes to aluminum, 6061 may be used the most, but it’s not the answer to the question of which aluminum is strongest. That distinguished honor goes to 7075. Look no further than the fact the aerospace industry uses 7075 aluminum for structural components. With that in mind, it’s a good bet that it will hold up to the strength test of your application, too.
Part of the 7000 series of aluminum, 7075 contains zinc as its major alloying element. When coupled with a small percentage of magnesium, the result is a heat-treatable alloy with very high strength. Like other grades in the 7000 series of aluminum, 7075 aluminum uses small quantities of copper and chromium as well. This grade conforms to AMS QQ-A-225/9 and ASTM B211.
Various methods of cold working are typically used to reduce the internal residual stress resulting from prior heat treatment. Stretcher level and compressing are two of common cold-working methods used on 7075 aluminum.

A member of the 7000 series, it is one of the strongest alloys available and is comparable to many types of steel. Although it has high strength, it has lower corrosion resistance than other common aluminum alloys and does not offer the same levels of machinability or weldability.

7075 is able to match most steel alloys in terms of strength. ... On the other hand, 7075 is one of the strongest aluminum alloys available. While 7075 is less workable than 6061, if your greatest consideration is strength, then 7075 is probably the better choice.
