1000 series aluminum alloy is considered to be pure aluminum. There are slight differences between 1050 and 1060 aluminum alloys in terms of alloy composition, performance, use and application range. 1050 aluminum alloy contains more than 99.5% aluminum, and 1060 aluminum alloy contains more than 99.6% aluminum. Neither of them can be strengthened by heat treatment, and their strength is relatively low.
1060 is suitable for stretching and other products. It has the characteristics of high plasticity, corrosion resistance, good electrical conductivity and thermal conductivity. 1050 aluminum alloy has gradually been replaced by 1060 aluminum alloy.
1050 vs 1060 Chemical Composition
The aluminum content of 1050 aluminum alloy is more than 99.50% and does not contain copper. The aluminum content of 1060 aluminum alloy is more than 99.60% and contains a small amount of copper (not more than 0.05%).
