The aluminum sheet for the aluminum alloy mold is usually a high strength and heat treatment alloy, which needs good mechanical properties, easy to use and easy to process. According to the use and characteristics of the mold, aluminum also needs to have corrosion resistance and oxidation resistance.
Hot-rolled plate refers to aluminum plates with a thickness of 4.5 mm or more, it is widely used for tankers, ships, moulds, containers, pressure vessels, automobiles, construction machinery, etc.Hot-rolled thick aluminum plate has one more annealing step than the cast-rolled aluminum plate, so it solve some defects, such as component segregation and impurities
