Aluminium 1050 h24

What is 1050 H24 aluminum?

1050 aluminum is a commercially pure grade aluminum belonging to the 1000 series, meaning it contains at least 99.5% aluminum. In the H24 temper, this alloy undergoes strain hardening (cold working) followed by partial annealing. The H24 designation provides a strength level approximately between fully annealed (O temper) and fully strain-hardened (H28 temper) states. This tempering process optimizes the balance between increased mechanical strength and retained ductility, making it suitable for various applications.

1050 H24 aluminum balances moderate strength with good ductility, making it ideal for applications requiring formability and corrosion resistance. As part of the 1000 series, it is known for its high electrical conductivity/thermal conductivity and excellent workability.

Alloy Composition: The designation "1050" indicates that the main element of this aluminum plate is pure aluminum, with a minimum purity of 99.5%. This is considered an industrial pure aluminum alloy, known for its excellent corrosion resistance and good formability.
