Item Descriptions:
-Zinc is a bluish-white metal
-Zinc is a bluish-white metal. A density of 7.14 g / cc, a melting point of 419.5 ¡æ. At room temperature, brittle; 100 ~ 150 ¡æ,become softened; exceed 200 ¡æ, they become brittle. Zinc chemically is active. In the air of normal temperature,the surface will form a layer of zinc carbonate film.It can prevent further oxidation

- Zinc is a bluish-white metal. A density of 7.14 g / cc, a melting point of 419.5 ¡ãC. At room temperature, brittle; 100 ~ 150 ¡ãC, become softened; exceed 200 ¡ãC, they become brittle.
- The chemical properties of zinc are active. In the air at room temperature, a thin and dense basic zinc carbonate film is formed on the surface to prevent further oxidation. When the temperature reaches 225¡ãC, zinc oxidation is intense. When it burns, it emits a blue-green flame.
- It is apply for the materials of instrument parts and instrument shells and coins. At the same time, zinc itself and other metals will not cause sparks, so it is fit for underground explosion-proof equipment. It is widely used in rubber, paint, enamel, medicine, printing, fiber and other industries.
