Advantages and disadvantages of aluminum alloy major advantage Light weight and high strength: the density is about 2³, which is only 1/3 of that of steel, and the specific strength is high, which is beneficial to reducing the structural weight. Strong corrosion resistance: the surface is easy to form a dense oxide film, which has corrosion resistanceally does not need special anti-corrosion treatment. Processing and environmental protection: good electrical and thermal conductivity, easy extrusion, non-toxic, recyclable and high utilization rate. Beautiful and durable: good surface luster and various colors, and trvicelife can reach more than 30 years under normal use. Main disadvantages Higher cost: raw materials and production costs are usually higher than ordinary steel, and the price is relatively expensive. Physical performance limitations: the elastic modulus is about 1/3 of that of steel, and the stiffness is low; High thermal conductivity, poor thermal insulation when used as building doors and windows. Insufficient experience: the toucd and hard, the wear resistance is poor compared with steel, and it is difficult and costly to repair after collision.
