Do you know 7075 aluminum heat treatment?

Last Updated: 2020-05-29

The 7075 aluminum sheet is a prodsuct that is frequently used because of its strength, toughness and corrosion resistance. It is in fact one of the strongest aluminum alloys out there. Its weight-to-strength allows it to be used for high stressed parts. In the annealed condition, the 7075 aluminum can be formed using heat methods. It’s not good with cold working. Once formed, it’s recommended that heat treatment be used. The springback of this metal is greater when being formed. To help make this metal more easily formed while in the annealed condition, it can be placed in temperatures between 200 and 250 degrees F. Heat treatments can be used to improve the hardness of this alloy. The properties of this alloy are excellent in low temperatures as well.

7075 Aluminum is near the top of the list among aluminum alloys manufactured for the needs of consumer and industrial markets. Among other 7XXX alloys, alloy 7075 exists as a standard with a solid mix of properties suitable for aircraft and aerospace applications. In particular, this alloy utilized in various forms, including as 7075 aluminum bars, is well-suited for use in parts that endure high stress levels. The strength properties of alloy 7075 are beneficial for the manufacture of items such as aircraft structures, military grade rifles, bicycle parts and equipment, and plastic industry molds.

An aluminum alloy best suited for aerospace and aviation applications is 7075 T651. This tempered alloy has a high tensile strength which makes it particularly applicable for certain high-strength applications.
