1100 h18 aluminum sheet
1100 H18 aluminum alloy is based on 1100 aluminum alloy and has undergone specific temper treatment. It belongs to the high-purity aluminum alloy series, with an aluminum content typically above 99%, providing excellent corrosion resistance and electrical conductivity.
1100-H18 aluminum sheet is a commercially pure aluminum alloy. The "H18" temper designation indicates that the material has been strain-hardened to a fully hard condition, increasing its strength while reducing ductility.
1100-H18 aluminum sheet is a high-purity, strain-hardened alloy known for its balanced formability, corrosion resistance, and moderate strength.
H18 indicates a full-hard temper achieved through strain hardening. Compared with softer tempers such as O or H14, this temper enhances tensile strength but reduces ductility.
What does H18 mean in aluminum?
H18 indicates that the aluminum alloy has undergone "hardening" treatment, primarily through strain hardening to improve the material's strength, resulting in higher hardness and strength. H18 is the strongest temper of 1100 aluminum alloy, typically used in applications that require higher strength but less ductility.
