Auto parts are becoming lighter and lighter with global trend of pursuing weight reduction for cars, which enhances the application of red anodized aluminum sheets, blue alu sheets, brushed alu sheets and other types of alu products in car making. In particular, a red anodized alu sheet is made into bonnets, trunk lids, door panels and interior decorative panels of cars. These sheets can be of 1000, 3000, 5000, 6000 and 7000 series according to the level of a car and the parts they are made into. 1000 and 3000 series are enough for inner panels, for the panels are not exposed to severe chemical and mechanical conditions, thus they require less in corrosion resistance and hardness. But truck lids and door panels, which are exposed to the outdoor atmosphere and are likely to be knocked by fierce forces, must be made of stronger alloys like 6061 and 7075. Haomei supplies alloys of 1060, 1070, 1100, 3003, 3004, 3005, 5005, 5052, 5083, 6061, 6082 and 7075 for red anodized alu sheets.
Red anodized aluminum sheets are applied to auto parts for the following advantages. First, they are lighter than any other suitable auto materials, for the density of aluminium is almost the smallest of all common metals. Second, they are fire-proof. Aluminium sheets withstand very high temperatures, and they do not catch fire easily like non-metal materials. Third, they are flatter than mill finish aluminium sheets, not to mention other materials. This enhances the level of a car visually. And the red color makes a car cool and attractive. Fourth, they have excellent wear resistance and corrosion resistance. Beautiful red anodized coating acts as an insulation layer and a hard protective layer, extending the service life of a car panel. Fifth, they show outstanding processing properties. Red anodized aluminium sheets can be bent or cut at will, without any cracking, breaking or burring phenomena. Sixth, they are cost efficiency. Although aluminum sheets seem to be more expensive than other metal sheets, they win in small density and large volume. A ton of aluminum sheets can be made into door panels 3 times of the numbers of one ton of steel panels.
