1070 aluminum bar is a high-purity solid round/square aluminum bar belonging to the 1000-series commercial pure aluminum family, with a standard aluminum purity of ≥99.7%. It is a non-heat-treatable aluminum alloy whose hardness can only be improved by cold working processes. Featuring ultra-high electrical and thermal conductivity, excellent ductility, smooth surface finish, superior atmospheric corrosion resistance and easy machinability, this aluminum bar supports cutting, drilling, bending, stamping and welding. It is non-toxic, non-magnetic and 100% recyclable. Compared with 1060 aluminum bar, 1070 aluminum bar has higher purity and more stable conductive and heat-conducting performance. With low mechanical strength, it is widely used for electrical conduction, heat dissipation, corrosion-resistant structural accessories and precision processing parts with no high load-bearing requirements.
