3105 h24 aluminum sheet plate

3105 H24 aluminum is a treatment state of 3105 aluminum alloy, where "H24" indicates that the metal has undergone strain hardening and partial annealing.

3105 H24 aluminum plate is a medium-strength aluminum alloy plate based on aluminum-manganese alloy, belonging to the 3xxx series of wrought aluminum alloys.

3105 H24 aluminum plate is a non-heat-treatable aluminum-manganese alloy, mainly composed of aluminum with small additions of manganese, magnesium, and silicon to improve strength. In the H24 temper (solution annealed followed by cold working to a certain hardness), it combines excellent formability, corrosion resistance, and weldability with moderate strength and good plasticity, making it widely used in applications requiring coating or decorative surfaces, such as building curtain walls, decorative panels, and traffic signs.

The 3105 H24 alloy has undergone strain hardening and partial annealing treatment to reach the H24 temper, thus balancing strength and formability.

3105 aluminum alloy has higher strength than 1000 series (e.g., 1100) and 3000 series (e.g., 3003) alloys, while maintaining good ductility and corrosion resistance. This alloy cannot be strengthened by heat treatment, and mainly achieves the required hardness grade through cold working processes (such as rolling or stretching), where H24 indicates a "solution treated + ¼ hard" temper.
