The chemical symbol of zinc is Zn, its atomic number is 30, and it is located in the 4th period and the IIB group in the periodic table of chemical elements. It is a light gray transition metal. Zinc is a silvery white metal with a slightly light blue color, a density of 7.14 g/cm3, and a melting point of 419.5 ℃. At room temperature, it is brittle; at 100~150°C, it becomes soft; after exceeding 200°C, it becomes brittle again. It plays an indelible role in battery manufacturing in modern industry and is a very important metal.

Precision machining:
Product precision is strictly controlled, high density and small tolerance

Corrosion resistance:
Zinc has excellent atmospheric corrosion resistance and is easy to form a protective film on the surface at room temperature

Anti-electromagnetic field:
The conductivity of zinc is 29% of standard electrical copper. Zinc plate is a very effective shielding material. At the same time, because zinc is non-magnetic, it is suitable for making materials for instrument parts and instrument housings, etc.

Has suitable chemical properties:
Zinc can react with NH4CI to release H+ positive ions. Zinc alloy is used as the battery shell, which is not only a container for battery electrolyte, but also participates in battery reactions to form the anode of the battery
