Aluminum sheet 1050 O H14 H16 H18 H24
The Aluminum Sheet 1050 is a highly versatile aluminum alloy known for its excellent corrosion resistance, high ductility, and great electrical and thermal conductivity. In its various temper states such as O, H14, H16, H18, and H24, 1050 aluminum sheet finds extensive applications across industries that demand both aesthetic qualities and functional performance.
1050 aluminum belongs to the commercially pure aluminum grades with a minimum of 99.5% aluminum content. It is non-heat-treatable, acquiring strength mainly through cold working. Due to its excellent combination of ductility, corrosion resistance, and workability, it's widely used in electrical transmission, food processing, and decorative applications.
Temper Designations (O, H14, H16, H18, H24)
| Temper | Description | Process | Approximate Hardness (HV) | Characteristics |
|---|---|---|---|---|
| O | Annealed (soft) | Fully annealed | ~25-30 | Maximum ductility, minimum strength |
| H14 | Strain-hardened (half-hard) | Rolling, 1/4 hard hardening | ~40-50 | Good formability with moderate strength |
| H16 | Strain-hardened (medium-hard) | Rolling, slightly harder than H14 | ~53-58 | Medium strength with lower ductility |
| H18 | Strain-hardened (hard) | Rolling, hard | ~63-67 | High strength with reduced formability |
| H24 | Strain-hardened and partially annealed (3/4 hard) | Cold working with some annealing | ~55-60 | Balance of strength and ductility |
