A1070
A1070 is a material of the pure aluminum system, and purity is 99.7% or more.
As it is not done for materials of the pure aluminum system that I add an element like other aluminum alloy and improve strength and extruded workability, one of (with the stickiness) soft low features the strength.
Corrosion resistance is high in purity for high purity more than 99.7% and is superior in thermal conductivity and conductivity. Therefore A1070 is used for heat exchanger parts or a machine part, power transmission and distribution-related parts.
By the way, "70" of the lower two digit of A1070 shows purity and understands that purity is 99.7%. For example, in A1100, A1050 shows that it is purity of 99.5% or more more than 99%.
