7075 Aerospace Extrusions

The principle alloying element in 7075 extrusion is Zinc. 7075 is one of the highest strength aluminum alloys available and is used in the structure of the aircraft wher the stress is high. It has a high strength-to-weight ratio. It can be formed in the annealed condition and can be heat treated 7075 to multiple tempers including 7075-0, 7075-T6511, 7075-T73511 and 7075-T76511.

In 1943 Alcoa introduced 7075 to the USA Market and is the priciple aluminum aircraft alloy of modern planes today.


How we can help

Our prints go back to the 1930's. We can make as little as 12ft, and if it's a relatively common shape we will not charge for the die. In addition to the extruded shape we go beyond, offering:

Mechanical Properties for 7075-T6511

Unlike bar and plate, aerospace profiles tensile and yield vary slightly depending on the wall thickness. Most sites provide limited information. The table below is taken from the 2017 Aluminum Standards and Data

Availability

Each alloy has a different temper or hardness. This temper translates into tensile strength and yield strength. Tensile strength is the point at which when the extrusion is pulled apart will snap. Yield strength is the point at which the extrusion is bent beyond its limits.
