DX51D galvanized sheet material is a non-ferrous alloy mainly  composed of zinc as the matrix and other elements. The main alloy  elements are aluminum, copper, magnesium, etc. Zinc alloy has low  melting point, good fluidity, easy plastic processing and welding, and  is resistant to atmospheric corrosion. 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. Its casting process performance is good, and the cooling rate has  little impact on the mechanical properties. It is mainly used to  manufacture mechanical parts, toys, decorations, household appliances,  etc. The commonly used wrought 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 alloy elements are added. It has high  strength and is easy to form. It can replace some brass or duralumin to  make precision forgings. The latter is 0.7%~1.5% copper, which can  increase the strength and impact toughness of the alloy and reduce the  plasticity. Zinc copper alloy is suitable for making daily hardware  products or replacing part of brass.

Advantages:  It not only has the mechanical strength and easy forming properties of  steel plates, but also has good decorative properties and corrosion  resistance of organic materials. The coating has strong adhesion and can  keep the color fresh for a long time. Application: Widely used in  various fields such as construction, home appliances, furniture, public  facilities and transportation.
