The industrial rolling of aluminum alloy sheets consists of 7 major operations: preliminary rolling of flat, continuously cast ingots with a weight of 0.5-5tons, straightening on roller straighteners, milling to obtain a pure and smooth surface, application of aluminum sheets to both sides of the ingot, heating, hot rolling with cladding to a thickness of 4-12mm with subsequent reeling, and finally, annealing and cold rolling. Our hot rolled sheets do not go through the cold rolling process.
Our 6-series hot rolled aluminum sheets, represented by aluminum alloy 6061 sheets, contains a larger amount of magnesium and silicone than other sheets. It features a high corrosion resistance and anti-oxidation features. As the alloy sheet has a high plasticity and excellent interfaces, as well as being easy to coat and process, it is primarily used in the production of low pressure weapons and plane adaptors. Customized aluminum sheets are also available upon request.
