The 1050 aluminum alloy is formed from pure aluminum by added a small amount of copper element, and the 1050 aluminum plate has low strength, excellent formability, surface treatment property, weldability and corrosion resistance. Besides, the industrial pure aluminum has the characteristics of high plasticity, corrosion resistance, electrical conductivity and thermal conductivity, but the strength is low, it can not be strengthened by heat treatment, the machinability is not good, and contact welding and gas welding are acceptable. The higher the purity, the lower the hardness of the aluminum plate, in the 1000 series pure aluminum alloys, 1050 aluminum has higher strength, it is almost the same as 1060 aluminum.
As one of the unalloyed aluminum, 1050 aluminum sheet has low price and high performance, so it also has wide applications. The thickness of 1050 aluminum plate sheet is 0.012-500mm. The tempers have soft state (O state, H111), hard state (H18, T6), medium hardness (H24, H22, H32, H112), etc. After other treatment or processing, the application scope of the 1050 aluminum alloy can be widen, such as 1050 mirror aluminum sheet, 1050color coated aluminum sheet, 1050 embossed aluminum sheet, 1050 aluminum trad plate, 1050 anodized aluminum sheet and 1050 brushed aluminum sheets. With so many performance advantages, 1050 aluminium can be applied in daily necessities, lighting equipment, reflectors, decorations, chemical industry containers, heat sinks, signs, electronics, lamps, nameplates, electrical appliances and other products.
