Which alloys can be made into a high reflect aluminum mirror coil sheet?
Theoretically, all aluminium alloys can be made into high reflect aluminum mirror coil sheet products, like 1050, 1060, 1070, 1100, 5052, 6061, 6063, 7075 and so on. However, the processing effect varies from alloy to alloy. For example, the polishing effect of the 5 series, 6 series and 7 series aluminum sheet coil proves to be better than that of the 1 series.
1 series, however, is the most frequently applied one. Basic alloys include 1050, 1060, 1070 and 1100. Also known as a pure aluminum plate, its purity (aluminium content) can reach 99.00% and above. Because it does not contain other technical elements, the production process is relatively simple and the price is relatively cheap. It is the most commonly used series in the conventional industry. Aluminum mirror sheet pieces made of such alloys are softer and weaker.
The other type of alloys are known as alloy aluminum plates, like 5052, 6061, 6063, 7075 etc. The application of 5000 series of high reflect aluminum mirror coil sheet is also quite a lot, aluminum plate belongs to the more common alloy aluminum plate series, the main element is magnesium, the magnesium content is between 3-5%. Also known as aluminum-magnesium alloy. The main features are low density, high tensile strength and high elongation. The weight of aluminum-magnesium alloy is lower than other series under the same area. Therefore, it is commonly used in aviation, such as aircraft fuel tanks. It is also widely used in conventional industries. The processing technology is continuous casting and rolling, which belongs to the hot-rolled aluminum plate series and can be used for oxidation deep processing. The 5000 series of aluminum plates are featured by mature process, and the alloy aluminum plate is also very good for the mirror effect.
In addition, a mirror finish anodized aluminum sheet is better in performance than a regular polished aluminum sheet. Correspondingly quality sheets cost more.
