6262 (AlMg1SiPb, A96262) Aluminum
6262 aluminum is a 6000-series aluminum alloy: there is significant alloying with both magnesium and silicon, and the alloy is formulated for primary forming into wrought products. 6262 is the Aluminum Association (AA) designation for this material. In European standards, it will be given as EN AW-6262. AlMg1SiPb is the EN chemical designation. And A96262 is the UNS number.
It originally received its standard designation in 1960. This material is well established: the Further Reading section below cites a number of published standards, and that list is not necessarily exhaustive.
The properties of 6262 aluminum include seven 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 6262 aluminum to: 6000-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 6262 aluminum is notable for including lead (Pb) and bismuth (Bi). Lead is used to improve machinability at the cost of toxicity and a decrease in weldability. Bismuth is used to improve machinability at the cost of a decrease in weldability.
