The characteristics and properties of

The outstanding characteristic of aluminum alloy is small density, high strength. Aluminum formed by adding Mn, Mg, Mn, Al - Mg alloy has good corrosion resistance, good plasticity and high strength, known as antirust aluminium alloy, used in the manufacture of oil tank, vessel, pipeline, rivets, etc. The strength of the hard alloy is antirust aluminium alloy is high, but corrosion protective performance declined, this kind of alloy has Al - Cu - department of Mg and Al - Cu - Mg - department of zinc. Newly developed high strength dural, further improve the intensity, the density is harder than ordinary aluminum decreases by 15%, and extrusion molding, can be used as a motorcycle frame and wheels and other components. Al - Li alloy making aircraft parts and can bear load, senior sports equipment.
