1100 h12 aluminum sheet plate
1100-H12 aluminum alloy is a type of alloy in the 1100 series. It belongs to aluminum materials that have been strain-hardened and are in the H12 temper. The H12 temper aluminum alloy lies between the annealed (O temper) and full-hard (H18 temper) states. Its strength is higher than the annealed state but still retains good ductility and excellent workability.
1100 H12 aluminum sheet is a commercial pure aluminum alloy, known for its excellent corrosion resistance, high workability, and low strength. In the H12 temper, it has undergone partial work hardening to improve its hardness, but it is not as hard as other tempers like H14 or H18.
1100-H12 aluminum sheet is a deformed aluminum alloy sheet made from industrial pure aluminum (aluminum content ≥99.00%) as the base material, cold-rolled and treated in the H12 temper (semi-hard state).
What is H12 in aluminium?
H12 temper aluminum alloy has a relatively low hardness and moderate tensile strength, making it suitable for applications that require certain strength and good workability.
