DX51D material:
The material of dx51d galvanized sheet is a non-ferrous alloy composed of zinc as the base and adding 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 is resistant to atmospheric corrosion.
According to the manufacturing process, it is 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 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.
Commonly used deformed zinc alloys include zinc-aluminum alloy and zinc-copper alloy.
The former contains 4% to 15% aluminum. In order to improve the strength and hardness of the alloy, a small amount of alloying elements such as copper and magnesium are also 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% to 1.5% copper. Copper can improve alloy strength and impact toughness and reduce plasticity. Zinc-copper alloy is suitable for making daily hardware products or replacing brass parts.
In addition, there are zinc-titanium-based and zinc-lead-cadmium-iron-based deformed zinc alloys. The supply status of deformed zinc alloy is wire rod, plate, forging or extrusion, etc.

DX51D+Z275 definition:
DX51D+Z275 is an ordinary material galvanized coil with a zinc coating of 275g.
DX51D+Z is called hot-dip galvanizing, and 275 means 275 grams of galvanizing. That is, a layer of zinc is coated on hot-dip galvanizing.
Generally speaking, N refers to the anti-fingerprint coating on the surface. A refers to A-level noodles. C stands for roll, coil, generally 1.0*1250*C (thickness, width, length). Generally, the rolls are random and represented by C.
DX51D Application:
Galvanized products are widely used in various fields such as industry, agriculture, animal husbandry and fishery, energy, transportation, chemical industry, light industry, home appliances, construction, communications, national defense, etc., and are widely used.
