Description

AD31 alloy used: for the manufacture of a cylindrical (solid and hollow) ingots cast by semi-continuous method or continuous casting and designed for production of bars, rods, profiles, panels, pipes of different sections, wire, forgings and stampings; parts of low strength and high corrosion resistance, working in range from -70 to +50 °C; profile pressed extra virgin for the manufacture of radiators of cooling of semiconductor devices; extruded by hot extrusion of profiles of constant cross section for use in enclosing building constructions and products.

Note

The alloy system Al-Mg-Si.
ISO 209−1 alloy brand AD31 is designated AlMg0,7Si and 6063.
