Product Description The material of dx51d galvanized steel sheet is a non-ferrous alloy composed of zinc as the matrix and other elements added. The main alloying elements are aluminum, copper, magnesium and so on. Zinc alloy has low melting point, good fluidity, easy plastic working and welding, and resistance to atmospheric corrosion. According to the manufacturing process, it is divided into cast zinc alloy and deformed zinc alloy. Commonly used cast zinc alloys are zinc-aluminum-copper-magnesium alloys, which have good casting process performance and little impact on mechanical properties. Commonly used wrought zinc alloys are zinc-aluminum alloy and zinc-copper alloy. The former contains 4% to 15% of aluminum. In order to improve the strength and hardness of the alloy, a small amount of alloying elements such as copper and magnesium are added. It has high strength and is easy to form, and can replace some brass or hard aluminum to manufacture precision forgings. The latt…
