2036 (2036-T4) Aluminum
2036 aluminum is a 2000-series aluminum alloy: the main alloying addition is copper, and it is formulated for primary forming into wrought products. Cited properties are appropriate for the T4 temper. To achieve this temper, the metal is solution heat-treated and naturally aged. 2036 is the Aluminum Association (AA) designation for this material. In European standards, it will be given as EN AW-2036. Additionally, the UNS number is A92036.
It originally received its standard designation in 1970.
The graph bars on the material properties cards below compare 2036 aluminum to: 2000-series alloys (top), all aluminum alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.

Alloy Composition
Among wrought aluminum alloys, the composition of 2036 aluminum is notable for containing a comparatively high amount of copper (Cu). Copper is used to improve strength. This comes at the cost of a decrease in corrosion resistance and weldability.
