The main alloying elements in 6061 alloy are the magnesium and silicon, which with moderate strength, good corrosion resistance, weldability, oxidation effect. And widely used in demanding a certain strength and high corrosion resistance of various industrial structural parts.
6061 aluminum plate is Al-Mg-Si alloy, medium strength, with good plasticity and excellent corrosion resistance. Especially stress-free corrosion cracking tendency, its good weldability, corrosion resistance and cold workability is good, is a wide range of use. Very promising alloy. Can be anodized coloring, but also painted enamel, to adapt to building decoration materials. Which contains a small amount of Cu, so the intensity is higher than 6063, but the quenching sensitivity than 6063 high, after extrusion can not be achieved wind quenching, need to re-solution treatment and quenching aging in order to obtain higher strength.
6061 aluminum plate requires a certain strength, weldability and corrosion resistance of a variety of industrial structures such as manufacturing trucks, take the building, ships, trams, furniture, machinery parts, precision machining, industrial materials and more widely.

Internationally, the thickness more than 0.2mm, bellow 500mm ,width above 200mm the length within 16m aluminum material is called aluminum sheet. the thickness bellow 0.2mm is called aluminum foil. the width within 200mmcalled the row or the strip (with the progress of large equipment, the widest of the row material can be 600mm even more).
