The 5000 series is a more commonly used alloy aluminum plate. The main component element is magnesium, and the magnesium content is between 3-5%. The main features are low density, high tensile strength and high elongation. In the same area, the weight of aluminum-magnesium alloy is lower than other series, so it is often used in aviation. 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, so it can be used for deep oxidation processing.
