Zinc ingots are divided into different types according to different zinc contents. The functions of different types will naturally be different. Not only that, zinc ingots with different zinc contents also contain completely different impurities. Zinc is cast into different brands of zinc ingots based on different chemical compositions. Below, we, a long-term supplier of zinc ingots, will give you a detailed understanding of the impurity content and functions of different types of zinc ingots.

(1) No. 0 zinc, the zinc content is not less than 99.995%. The main impurity elements are the same as No. 1 zinc, but the content is slightly different. Lead is 0.003%, cadmium is 0.002%, iron is 0.001%, copper is 0.001, and tin content is 0.001. It is used for manufacturing advanced alloys and special purposes.

(2) No. 1 zinc, the zinc content is not less than 99.99%. The main impurity elements are the same as No. 2 zinc, with lead 0.005%, cadmium 0.003%, iron 0.002%6, copper 0.002, and tin content 0.001. Mainly used for high-grade zinc oxide, pharmaceutical and chemical reagents, electroplating zinc, and die-cast parts.

(3) No. 2 zinc, the zinc content is not less than 99.95%. The main impurity elements are the same as No. 3 zinc, including lead 0.02%, cadmium 0.02%, iron 0.01%, copper 0.002, and tin content 0.001. It is mainly used for making zinc alloys, battery zinc sheets and die-cast parts.

(4) No. 3 zinc, the zinc content is not less than 99.90%. The main impurities are: lead, cadmium, copper, iron, and tin, mainly used in zinc plates, hot-dip galvanizing and copper alloys.

(5) No. 4 zinc, the zinc content is not less than 99.5%. The main impurities are: lead, iron, cadmium, copper, arsenic, antimony, tin, aluminum, lead 0.3%6, cadmium 0.07%, iron 0.04%6, copper 0.002, tin content 0.002, aluminum 0.01%, arsenic element The content of antimony is 0.005%, 0.01, etc. Mainly used for making zinc plates, zinc powder, hot-dip galvanizing, ordinary castings and zinc oxide.

(6) No. 5 zinc, the zinc content is not less than 98.7%. The main impurities are: lead, iron, cadmium, copper, arsenic, antimony, tin, aluminum, lead 1.0%, cadmium 0.20%, iron 0.05%, copper 0.005%, tin content 0.002%6, aluminum 0.01%, arsenic The element content is 0.01%, the content of antimony is 0.02%, etc. Mainly used for making zinc-containing copper-lead alloys, ordinary zinc oxide and ordinary castings.

Zinc ingots refer to pure zinc. Of course, there will be impurities, but as zinc ingots, they must be at least 90% pure. Uses of zinc ingots: Mainly used in die-cast alloy battery industry, printing and dyeing industry, pharmaceutical industry, rubber industry, chemical industry, etc. Alloys of zinc and other metals are widely used in electroplating, spraying and other industries.
