polished aluminum panels

The surface brightness of polished aluminum panels is close to or equal to that of mirrors, with high surface gloss and fine texture. They are mostly used in reflective lighting, indoor and outdoor architectural decoration, automobile interior and exterior decoration, high-end switch panels, and various high-end label nameplates (foreign wine labels).


 
Because this product is an aluminum alloy sheet and strip with ultra-high surface quality requirements, it is very difficult to research and develop this product. Some domestic aluminum rolling enterprises also develop this product, but the effect is not satisfactory, mainly in the rough surface texture. , Low gloss, many surface quality defects and other problems.
 
Henan Signi Aluminium Co., Ltd. based on the existing tooling conditions in 2012, used a 1400mm cold rolling mill to conduct process research on aluminum alloy plates and strips for 1070 aluminum alloy mirrors. Through process research, difficult problems such as poor surface brightness, rough texture, and multiple surface quality defects have been gradually solved, so that our company can stably produce mirror aluminum products with high surface reflectivity, and the longitudinal gloss can reach more than 780GS stably, and the highest can reach 820GS meets the needs of the domestic market. Some products can replace imported mirror aluminum, breaking the long-term dependence of domestic high-end mirror aluminum products on imports, which is of great significance.
 
 
Polished aluminum panels and strips for rolling mirrors are mainly made of 1070 aluminum alloy, supplemented by aluminum alloys such as 3 series and 8 series.
