The features of 1070 aluminium 1070 aluminum for the aluminum industry.Industrial aluminum with aluminum the general characteristics, density, electrical conductivity, good thermal conductivity, good corrosion resistance, plastic processing performance, can be processed into plate, strip, foil and extruded products, etc., can be welding, spot welding. Industrial pure aluminum can not be heat strengthened, through increased intensity of cold deformation, the only form of heat treatment is annealing.
1070 Aluminum Applications
Widely used in less demanding on the strength of the product, such as chemical equipment, sheet metal processing parts, deep drawing or spinning hollowware, welding parts, heat exchangers, bell surface and disk, plate, kitchenware, decorations, utensils and other reflective.

Note: The vertical bar at room temperature mechanical properties
1070 aluminum heat treatment
1) complete annealing: heating 390 ~ 430 ℃; with the effective thickness of different materials, heat preservation time 30 ~ 120min; to 30 ~ 50 ℃ / h speed with furnace cooling to 300 ℃, the re-cooled.
- rapid thermal annealing: heating 350 ~ 370 ℃; with the effective thickness of different materials, heat preservation time 30 ~ 120min; air or water.
- Quenching and aging:hardening 500~510℃;air-cooled;artificial aging 95~105℃,3h,air-cooled;nature aging at room temperature 120h
