What is the application of zinc ingot


The main application of zinc ingot is shown in the following aspects:

A, galvanized

Zinc has excellent resistance to atmospheric corrosion, so it is mainly used in steel and steel structure of the surface coating (such as galvanized sheet), widely used in automotive, construction, shipping, light industry and other industries. In recent years, western countries began to try to directly use zinc alloy board to do roof covering material, its service life can be up to 120-140 years, and can be recycled, and use galvanized iron board as roof material service life is generally 5-10 years.

2. Manufacture of copper alloys (such as brass)

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

Used for casting zinc alloy

Mainly for die casting, used in automotive, light industry and other industries. The processing performance of many zinc alloys is better, and the processing rate can reach 60%-80%. Medium pressure performance is superior, can carry on the deep drawing, and has the self-lubricity, prolongs the mold life, can use the brazing or the resistance welding or the arc welding (needs in the helium gas) to carry on the welding, the surface can carry on the electroplating, the coating treatment, the cutting processing performance is good. 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. Zinc oxide, about 11%

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

V. used for manufacturing 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+ positive ions. Zinc - manganese dioxide battery is to take advantage of this characteristic of zinc, zinc alloy battery shell, as the battery electrolyte container, and participate in the battery reaction to form the battery anode. This property is also widely used in the pharmaceutical industry.
