The 5005 aluminum coil belongs to the most commonly used alloy, the main element is magnesium, and the magnesium content is between 3 -5 %. It can also be called aluminum magnesium alloy. The main features are low density, high tensile strength and high elongation. The weight of the aluminum magnesium alloy under the same area is lower than that of the other series. Therefore, it is often used in aviation, such as the aircraft fuel tank. It is also widely used in conventional industries. The processing technology is continuous casting continuous rolling, which belongs to the series of hot-rolled aluminum coil.
