HOME ꄲ PRODUCTS ꄲ product details

Aluminum alloy 1050 is industrial pure aluminum, which has high plasticity, corrosion resistance, electrical conductivity and thermal conductivity, but its strength is low, heat treatment can not strengthen, and its machin ability is poor;

It can be gas welding, hydrogen atom welding and contact welding, not easy to braze; Easy to bear all kinds of pressure processing and drawing, bending.

Characteristics

Industrial pure aluminum has the general characteristics of aluminum, with small density, good conductivity, heat conduction, good corrosion resistance and good plastic processing performance. It can be processed into plates, strips, foil and extruded products, and can be used for gas welding, argon arc welding and spot welding.

The industrial pure aluminum can not be heat treated and strengthened, and the strength can be improved by cold deformation.

The only heat treatment form is annealing. The recrystallization start temperature is related to impurity content and deformation degree, generally about 200 ℃. 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 of the value decreased to 1% ~ 1.5%.

The increase of iron and silicon impurities can improve the strength, but reduce the plasticity, conductivity and corrosion resistance. The mechanical properties of 1200 (L5) industrial pure aluminum plate can be obtained by adjusting the annealing temperature or controlling the cold deformation. In order to improve form ability, the former method is better

Applications

Used in daily necessities, lighting appliances, reflective plates, decorations, chemical industry containers, heat sinks, signs, electronics, lamps, nameplates, electrical appliances, stamping parts and other products.

In some occasions where both corrosion resistance and form ability are required, but the strength requirement is not high, chemical equipment is its typical use.
