Classification of aluminum alloys

Cast Aluminum Alloys can be classified according to chemical composition of Al-Si alloys, aluminum-copper alloys, magnesium alloys and aluminum-zinc alloy. A pure aluminum products aluminum smelting products and pressure processed sub categories, the former chemical composition Al said the latter with pinyin LG (aluminum, industrial use) expressed. Second, the pressure processing aluminum alloy pressure processing products into rust (LF), hard (LY), forging (LD), hard (LC), coated (LB), special (LT) and the solder ( LQ) and other seven categories. State of the aluminum alloy material used annealing (M annealing), hardened (Y), hot (R), three. Third, aluminum and aluminum alloy processed into a certain shape of the material referred to aluminum, including plate, strip, foil, tubes, rods, wire, type. Fourth, cast aluminum cast aluminum alloy (ZL) by components outside the main elements of aluminum silicon, copper, magnesium, zinc divided into four categories, namely 100,200,300,400 code encoding. Five, high-strength aluminum alloy high strength aluminum alloy means a tensile strength greater than 480 MPa aluminum, primarily in hard aluminum alloy pressure processing class, hard aluminum alloy casting classes and categories.
