PRODUCT DETAILS
DX51D/ SGCC Galvanized Coil Description
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.
Scope of Application
Galvanizing products are widely used in industry, agriculture, animal husbandry and fishery, energy, transportation, chemical industry, light industry, home appliances, construction, communications, national defense and other fields.
