YTGZS Zinc Foil High Purity Pure Zinc Zn Sheet Plate Metal Foil a roll,0.1mmx100mmx1000mm

The chemical properties of zinc are active. Zinc has suitable chemical properties. 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°C, zinc oxidation is intense. When it burns, it emits a blue-green flame. Atomic radius (calc) 135 (142) pm,Covalent radius 131 pm. The melting point of zinc is 419.5°C. At room temperature, it is brittle; at 100-150℃, it becomes soft; when it exceeds 200℃, it becomes brittle. It is suitable 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 suitable for underground equipment. It is widely used in rubber, paint, enamel,printing, fiber and other industries. Zinc has suitable mechanical properties,The strength and hardness of zinc itself are not high, but after adding alloying elements such as aluminum and copper, its strength and hardness are greatly improved.
