Description
Description of 1070 Aluminum Sheet/Plate
1070 aluminum sheet/plate belongs to the 1000 series of aluminum alloys, which are known as commercially pure aluminum. The “1070” designation signifies that the alloy contains a minimum of 99.7% aluminum, with very small additions of other elements like iron and silicon to slightly enhance its properties.
This high purity makes 1070 aluminum stand out for its exceptional electrical and thermal conductivity, excellent corrosion resistance, and high plasticity. It is a non-heat-treatable alloy, meaning its strength cannot be significantly increased through heat treatment processes. While its strength is relatively low compared to other aluminum alloys, its ductility and formability are superior, making it easy to bend, stamp, deep draw, and weld (including gas and contact welding).
