1050-H14 Aluminum
1050-H14 aluminum is 1050 aluminum in the H14 temper. To achieve this temper, the metal is strain hardened to a strength that is roughly halfway between annealed (O) and full-hard (H18). The graph bars on the material properties cards below compare 1050-H14 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.
