DX51D GALVANIZED SHEET

DX51D galvanized sheet material is a nonferrous alloy composed of zinc as the matrix and other elements. The main alloying elements are aluminum, copper, magnesium, etc. Zinc alloy has a low melting point, good fluidity, easy plastic processing and welding, and atmospheric corrosion resistance. According to the manufacturing process, it can be divided into cast zinc alloy and deformed zinc alloy. The commonly used cast zinc alloy is zinc-aluminum-copper-magnesium alloy, which has good casting process performance and little effect of cooling rate on mechanical properties. It is mainly used to manufacture mechanical parts, toys, decorations, household appliances, etc. Commonly used deformed zinc alloys are zinc-aluminum alloy and zinc-copper alloy. The former contains 4%~15% aluminum. In order to improve the strength and hardness of the alloy, a small amount of copper, magnesium and other alloying elements are added. It has high strength and is easy to form. It can replace part of brass or hard aluminum to make precision forgings. The latter contains 0.7%~1.5% copper, which can improve the strength and impact toughness of the alloy and reduce plasticity. Zinc-copper alloy is suitable for making daily hardware products or partially replacing brass.
