DX51D/ SGCC Galvanized Coil

The material of DX51D galvanized sheet is a non-ferrous alloy with zinc as the matrix and other elements. The main alloying elements are aluminum, copper, magnesium and so on. Zinc alloy has low melting point, good fluidity, easy plastic processing and welding, and resistance to atmospheric corrosion. According to the manufacturing process, it is divided into cast zinc alloy and deformed zinc alloy. The commonly used casting zinc alloy is zinc-aluminum-copper-magnesium alloy, which has good casting process performance, and the cooling rate has little effect on the mechanical properties. They are mainly used in the manufacture of mechanical parts, toys, decorations and household appliances.
