The thermal conductivity and electrical conductivity are high, and the weldability and corrosion resistance are good.
A1070 is made of pure aluminum material, with a purity of over 99.7%.
As it is a pure aluminum material, it does not have elements added like other aluminum alloys to improve strength or extrudability, resulting in lower strength and a characteristic softness (ductility).
Due to its high purity of over 99.7%, it has excellent corrosion resistance, as well as superior thermal conductivity and electrical conductivity. Therefore, A1070 is used in heat exchanger components, machine parts, and components related to power transmission and distribution.
By the way, the last two digits of A1070, "70," indicate its purity, confirming that it has a purity of 99.7%. For example, A1100 indicates a purity of over 99%, while A1050 indicates a purity of over 99.5%.
