Physical Characteristics of 3003 Aluminum

Aluminum alloys have varying degrees of formability, mechanical processing, corrosion resistance, strength, and heat resistance, and the proportion of alloy composition determines the differences. 3003 aluminum alloy is a commonly used aluminum material, and the addition of manganese element improves the strength and greatly improves the utilization rate of 3003 aluminum alloy.

The strength of 3003 aluminum alloy is 20% higher than that of 1100 aluminum alloy. In terms of strength indicators, 3003 aluminum alloy belongs to the medium level, and can be hardened without any heat treatment when cold worked into a hard alloy.

Mechanical deformation, good formability, according to different application processing methods, hammering and rolling techniques, H18 hardened 3003 aluminum is of excellent grade in terms of corrosion resistance, weldability, and formability.
