ASTM B209 Alloy 3003 H14

2023-03-22

ASTM B209 alloy 3003 h14 is a typical Al-Mn antirust alloy. The addition of the alloy component Mn slightly improves the compressive strength while maintaining the excellent processability and corrosion resistance of pure aluminum. Aluminum 3003 alloy is an alloy without heat treatment and cannot be strengthened through heat treatment, so the traditional cold drawing method can improve its physical properties. In addition, aluminum alloy 3003 h14 has excellent weldability, formability and other advantages, and has become a popular and economical choice for "electrical components". The internal stress of this board is cleared and does not deform during the cutting process, the maximum width is 2650mm, and the maximum thickness is 500mm.

The corrosion resistance of ASTM B209 alloy 3003 h14 is very good, which is close to the corrosion resistance of pure aluminum in industrial production. It has excellent corrosion resistance, and the corrosion resistance in dilute alkali is also very good. When the performance of aluminum sheet 3003 is in the state of cold deformation, the 3003 h14 aluminum alloy tends to fall off and corrode. The larger the deformation, the more serious the fall off. Because the color is uneven after anodizing, it is generally not anodized. The compressive strength of 3003 h114 aluminum alloy is 120-160 σb (MPa), standard tensile strength σ0.2 (MPa) )≥85.
