Zinc ingots can be classified into different types based on their zinc content;

(1) Zinc No. 0. ① The zinc content in zinc ingots shall not be less than 99.995%; ② The main impurity elements are the same as No.1 zinc; ③ Used for manufacturing advanced alloys and special applications.

(2) Zinc No.1. ① The zinc content in zinc ingots shall not be less than 99.99%; ② The main impurity elements are the same as the second zinc; ③ Mainly used for advanced zinc oxide, pharmaceutical and chemical reagents, electrogalvanizing, and die-casting parts.

(3) Second zinc. ① The zinc content in zinc ingots shall not be less than 99.95%; ② The main impurity elements are the same as the third zinc; ③ Mainly used for making zinc alloys, battery zinc sheets, and die-casting parts.

(4) Zinc No. 3. ① The zinc content in zinc ingots shall not be less than 99.90%; ② The main impurities are: lead, cadmium, copper, iron, and tin; ③ Mainly used for zinc plates, hot dip galvanizing, and copper alloys.

(5) Zinc No. 4. ① The zinc content in zinc ingots shall not be less than 99.5%; ② The main impurities are: lead, iron, cadmium, copper, arsenic, antimony, tin, and aluminum; ③ Mainly used for making zinc plates, zinc powder, hot-dip galvanizing, ordinary castings, and zinc oxide.

(6) Zinc No. 5. ① The zinc content in zinc ingots shall not be less than 98.7%; ② The main impurities are: lead, iron, cadmium, copper, arsenic, antimony, tin, and aluminum; ③ Mainly used for producing zinc containing copper lead alloys, ordinary zinc oxide, and ordinary castings.

The zinc content in zinc ingots determines the type of zinc ingot, and investors should be cautious when choosing zinc ingots
