The main application scope of zinc ingot is introduced

Main application range of zinc ingot

(a) galvanized

Zinc has excellent atmospheric corrosion resistance, so it is mainly used in the surface coating of steel and steel structural parts (such as galvanized sheet), widely used in automobile, construction, shipbuilding, light industry and other industries. In recent years WESTERN countries began to try to do roofing cover material directly with zinc alloy plate, its service life can be as long as 120-140 years, and can be recycled and reused, and the service life of roofing material with galvanized iron plate is generally 5-10 years.

(2) Manufacture of copper alloys (e.g. Brass)

Used in automobile manufacturing and machinery industry. Zinc has suitable mechanical properties. The strength and hardness of zinc itself is not high, but after adding aluminum, copper and other alloy elements, its strength and hardness are greatly improved, especially the appearance of zinc-cu-titanium alloy, its comprehensive mechanical properties have been close to or reached the level of aluminum alloy, brass, gray cast iron, its creep resistance is also greatly improved. Therefore, zinc-cu-Ti alloy has been widely used in hardware production.

(3) for casting zinc alloy

Mainly for die casting, used in automobile, light industry and other industries. The machining properties of many zinc alloys are relatively good, and the processing rate can reach 60%-80%. Excellent medium pressure performance, can carry on deep drawing, and has self-lubricity, prolong the life of the mold, can be brazed or resistance welding or arc welding (in helium gas) welding, surface can be electroplated, paint treatment, good cutting performance. It has superior superplastic energy under certain conditions.

In addition, zinc has good resistance to electromagnetic field. The conductivity of the zinc is 29% of the standard electrical copper, in the case of radio frequency interference, zinc plate is a very effective shielding material, at the same time because of the zinc is magnetic, suitable materials for instrument parts and instrument shell and coin, in the meantime, zinc itself and collisions with other metals not happen spark, for mine explosion-proof equipment.

(4) for the manufacture of zinc oxide, accounting for about 11%

Widely used in rubber, paint, enamel, medicine, printing, fiber and other industries.

(5) For the manufacture of dry batteries, in the form of zinc cake and zinc plate, accounting for about 13%.

Zinc has suitable chemical properties. Zinc can interact with NH4CI to release H+ ions. Zinc-mno2 battery makes use of this characteristic of zinc, and uses zinc alloy as the shell of the battery, which is not only the container of electrolyte, but also participates in the battery reaction to form the anode of the battery. Its performance is also widely used in the pharmaceutical industry.
