# 1060-H18 Aluminum

1060-H18 aluminum is 1060 aluminum in the H18 temper. This is the strongest temper normally produced through the action of only strain hardening. The graph bars on the material properties cards below compare 1060-H18 aluminum to: 1000-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.
