7075 Aluminum Alloy

Alro stocks 7075 Aluminum, an aluminum alloy with zinc as the primary alloying element. It is one of the strongest commercially available alloys, with a strength comparable to many steels. 7075 aluminum shows good fatigue strength and average machinability, however it is less resistant to corrosion than many other Aluminum alloys. 7075 can be formed by regular methods but requires more care and precision. It is primarily used in applications where cheaper alloys are not suitable, such as aircraft structural members.

7075 Aluminum is a very strong aluminum alloy. It is often comperable to steels in strength making it a good choice for the applications listed below:

7075-T6 aluminum belongs to the aluminum alloys classification, while ASTM A36 carbon steel belongs to the iron alloys. There are 31 material properties with values for both materials. Properties with values for just one material (1, in this case) are not shown. Please note that the two materials have significantly dissimilar densities. This means that additional care is required when interpreting the data, because some material properties are based on units of mass, while others are based on units of area or volume.

For each property being compared, the top bar is 7075-T6 aluminum and the bottom bar is ASTM A36 carbon steel.
