1080-H24 aluminum coil

1080-h24 aluminum coil has the general characteristics of aluminum, low density, good conductivity and thermal conductivity, good corrosion resistance and good plastic processability. It can be processed into plates, strips, foils and extruded products, and can be used for gas welding, argon arc welding and spot welding.

1080 aluminum coil 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, which is generally about 200 ℃. Of annealed sheet σ b=80～100MPa， σ 0.2=30～50MPa， ζ= 35％～40％，HB=25～30。 After 60% ~ 80% cold deformation, the disorder can be increased to 150 ~ 180MPa, but ζ The value decreased to 1% ~ 1.5%. Increasing the content of iron and silicon impurities can improve the strength, but reduce the plasticity, conductivity and corrosion resistance. The annealing softening characteristics and cold work hardening characteristics of 1200 (L5) industrial pure aluminum plate are shown in the figure. It can be seen from the figure that the mechanical properties of different cold work hardening states can be obtained by adjusting the annealing temperature after cold deformation or controlling the cold deformation after annealing. In order to improve formability, the former method is better.

1080-h24 aluminum coil application: 1080 aluminum coil is widely used as electrical aluminum, such as bus, wire, cable and electronic parts; It can be used as heat exchanger, cooler and chemical equipment; Packaging products for food and medicine such as tobacco, tea and sugar, and deep drawing products such as beer barrels; It is used as roof panel, ceiling, partition wall, sound-absorbing and thermal insulation materials, household appliances, cookers, etc.
