No. 0 zinc ingot is the highest grade of national standard zinc ingots, requiring zinc content to be no less than 99.995% and total impurity content no more than 0.005%. Metallic zinc has good ductility, wear resistance, corrosion resistance, castability, and excellent mechanical properties at ambient temperature. It can form high-performance alloys with many other metals. It is mainly used in the form of galvanized products, zinc-based alloys, and zinc oxide across industries such as automotive, construction, household appliances, shipbuilding, light industry, machinery, and batteries.
