Zinc (Zn)
We are a leading manufacturer and supplier of research materials
Zinc 30Zn65.37
Known in India and China before 1500.
[German, zink]
French: zinc
German: Zink
Italian: zinco
Spanish: cinc
Description: Zinc is a bluish-white metal that is brittle when cast. It tarnishes in air and reacts with acids and alkalis. Zinc is used for galvanizing iron, in alloys such as brass, and in batteries. Zinc oxide is used in rubber and as a polymer stabiliser.
