2014A (AlCu4SiMg(A), H15) Aluminum

2014A aluminum is a 2000-series aluminum alloy: the main alloying addition is copper, and it is formulated for primary forming into wrought products. 2014A is the Aluminum Association (AA) designation for this material. In European standards, it will be given as EN AW-2014A. AlCu4SiMg(A) is the EN chemical designation. And H15 is the British Standard (BS) designation.

It originally received its standard designation in 1976.

The properties of 2014A aluminum include fourteen common variations. This page shows summary ranges across all of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare 2014A 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 2014A aluminum is notable for containing a comparatively high amount of copper (Cu) and including nickel (Ni). Copper is used to improve strength. This comes at the cost of a decrease in corrosion resistance and weldability. Nickel is used to increase mechanical strength at elevated temperatures, and to reduce thermal expansion. However, it can increase susceptibility to pitting corrosion in certain alloys.
