PRODUCT DETAILS Description
1000 Series industrial pure aluminum has the general characteristics of aluminum, low density, good electrical and thermal conductivity, good corrosion resistance, good plastic processing performance, can be processed into plates, strips, foils and extruded products, etc., and can be used for gas welding, argon arc welding, spot welding. Industrial pure aluminum cannot be strengthened by heat treatment, but its strength can be improved by cold deformation. The only form of heat treatment is annealing. The recrystallization start temperature is related to the impurity content and deformation degree, generally around 200°C. σb=80～100MPa, σ0.2=30～50MPa, ζ=35%～40%, HB=25～30 of the annealed plate. After 60%-80% cold deformation, although it can be increased to 150-180MPa, the ζ value has dropped to 1%-1.5%. Increasing the content of iron and silicon impurities can increase the strength, but reduce the plasticity, conductivity and corrosion resistance. The mechanical properties of different cold hardening states can be obtained by adjusting the annealing temperature after cold deformation or controlling the amount of cold deformation after annealing. In order to improve formability, it is better to adopt the former method
