1070 aluminium cathode plates have the characteristics of high plasticity, corrosion resistance, good electrical conductivity and thermal conductivity, but low strength, not strengthened by heat treatment, poor machinability, and can accept contact welding and gas welding. Make full use of its advantages to manufacture some structural parts with specific performance, such as gaskets and capacitors made of aluminum foil, tube isolation nets, protective covers for wires and cables, nets, cores and aircraft ventilation system parts and decorative parts.

1070 aluminium cathode plates heat treatment process
Heat treatment process: Carry out oil quenching and tempering. The strength of this type of steel wire is not as good as that of lead bath, but the performance is uniform and the cost is lower. After cold roll forming, stress relief treatment is carried out. Pull to the specified size, and then perform annealing treatment. After the softened cold coil is formed, it needs to be quenched + tempered to obtain the required mechanical properties.
