Mill Finish 1050 1100 3003 3105 5052 Aluminum Steel Coil Cold Drawn Technology

1060 aluminum plate belongs to industrial pure aluminum, with high plasticity, corrosion resistance, electrical conductivity and thermal conductivity, but low strength, heat treatment can not be strengthened, machinability is not good; Gas welding, hydrogen welding and contact welding, not easy to braze; Easy to withstand all kinds of pressure processing and extension, bending.

1060 aluminum plate is widely used in products with low strength requirements. Products are often used in signs, billboards, building exterior decoration, bus body, tall buildings and factory wall body adornment, kitchen sink, lamp holder, fan blade, electronic parts, chemical equipment, mechanical parts, deep drawing of sheet or spinning concave ware, welding part, heat exchanger, clock surface and plate, plate, kitchenware, ornaments, reflective equipment, etc.

Industrial pure aluminum has the general characteristics of aluminum, small density, good electrical and thermal conductivity, good corrosion resistance, good plastic processing performance, can be processed into plates, belts, foil and extruded products, can be gas welding, argon arc welding, spot welding.

Industrial pure aluminum can not be strengthened by heat treatment, can improve the strength through cold deformation, the only form of heat treatment is annealing, recrystallization start temperature and impurity content and deformation degree, generally about 200℃. σ B= 80 ~ 100MPa, σ0.2=30 ~ 50MPa, ζ=35% ~ 40%, HB=25 ~ 30. After 60%-80% cold deformation, the ζ value decreases to 1%-1.5%, although the ζ value increases to 150-180mpa. Increasing the content of fe and Si impurities can improve the strength, but reduce the plasticity, electrical conductivity and corrosion resistance. The annealing softening characteristics and cold working hardening characteristics of 1200(L5) industrial pure aluminum sheet are shown in figure. It can be seen from the figure that mechanical properties of different hardening states can be obtained by adjusting the annealing temperature after cold deformation or controlling the cold deformation amount after annealing. In order to improve formability, it is better to adopt the former method.
