Brand newSize: approx. 100 times 100 times 0. 5mmDensity: 7. 14 g/ccMelting point: 419. 5 ?Feature: Make of High Purity zinc material, solid and durable, never rust. Suitable for: a variety of experimental situations. Zinc plates are widely used in exterior and interior room decoration, electrical, electronic goods, auto parts and drainage pipes. Chemical properties description: Zinc is a bluish-white metal. A density of 7. 14 g/cc, a melting point of 419. 5 ?. At room temperature, brittle; 100 ~ 150 ?, become softened; exceed 200 ?, they become brittle. In nature, the multi-state presence sulfide. 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.
