The application of polished aluminum sheet is very broad, mainly for lighting reflectors and lighting fixtures, solar heat-collecting materials, interior decoration, exterior wall decoration, household appliances panels, electronic products, automotive interior and exterior decoration, signs, bags and so on. Nowadays, there is a new type of curtain wall material which is made of high-quality mirror polished aluminum sheet coated with decorative paint and then formed by CNC bending and other techniques.
In the pure 1000 series, the aluminum content of 1050, 1060, 1070, 1100 pure aluminum is more than 99.9%, which is suitable for raw material for mirror aluminum sheet. To single-layer polished mirror aluminum sheet for curtain wall, 1100H24, 1060H24, 3003H24, 5005H24 aluminum can be used. The alloy of aluminum sheet 5005, 5657 series are mainly contains magnesium, the magnesium content is between 3-5%, and the 5000 series alloy aluminum sheet is very good for mirror surface effect. As the mirror polished aluminum sheet used for the facade of the building, the main use is the 5000 series aluminum-magnesium alloy aluminum plate, which has low density, high tensile strength and high elongation. The processing technology is continuous casting and rolling, which belongs to the hot-rolled aluminum plate series, so it can be used for anodizing deep processing. As a facade decoration, it can often achieve great effect of beautiful mirror surface.
