What is the scope of application of zinc ingot

Time2020.08.29

Zinc ingot refers to pure zinc, of course there will be impurities, but as a zinc ingot, at least 90% purity. USES of zinc ingot: mainly used in die casting alloy, battery industry, printing and dyeing industry, medicine industry, rubber industry, chemical industry, etc., the alloy of zinc and other metals is widely used in electroplating, spraying and other industries.

Zinc ingot is mainly used

A, galvanized

Zinc has excellent atmospheric corrosion resistance, so it is mainly used in the surface coating of steel and steel structure parts (such as galvanized sheet), widely used in automobiles, buildings, ships, light industry and other industries. In recent years, western countries began to try to use zinc alloy plate as roof covering material directly, and its service life can be as long as 120-140 years, and can be recycled for reuse, and the service life of galvanized iron plate as roof material 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 alloying elements, its strength and hardness are greatly improved, especially the appearance of zinc-Cu-Ti alloy, its comprehensive mechanical properties have approached or reached the level of aluminum alloy, brass and gray cast iron, and its creep resistance performance has also been greatly improved. Therefore, zinc-Copper-titanium alloy has been widely used in hardware production.

3. Used for casting zinc alloy

Mainly for die casting, used in automobile, light industry and other industries. Many zinc alloys have good machining performance, and the machining rate can reach 60%-80%. The medium pressure performance is superior, can carry on the deep drawing, and has the self-lubricity, prolonging the mold life, may use the brazing or the resistance welding or the electric arc welding (needs in the helium gas) carries on the welding, the surface may carry on the electroplating, the paint treatment, the cutting processing performance is good. It has superior superplastic energy under certain conditions.

In addition, zinc has good anti - electromagnetic properties. 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.

V. Used for manufacturing dry batteries, in the form of zinc cake and zinc plate, accounting for about 13%.

Zinc has appropriate chemical properties. Zinc can interact with NH4CI to release H+ positive ions. Zinc-manganese dioxide 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 battery electrolyte, but also participates in the battery reaction to form the anode of the battery. Its performance is also widely used in the medical industry.
