【Zinc Zn Sheet Plates Size】- Size: 100 × 100 × 0.5mm; Density: 7.14 g / cc; Melting point: 419.5 ℃
【Durable】- Make of high purity zinc material,solid and durable, never rust. Package included: 5pcs x zinc sheet plate
【Heat Treatable】- Zinc is a bluish-white metal.At room temperature, brittle; 100 ~ 150 ℃, become softened; exceed 200 ℃, they become brittle.
【Flat & Smooth Cutting Surface】- All the Zinc Zn Sheet Plates are precisely cut and the surfaces are processed to be smooth and flat with no crack or airhole. 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.
【Widely Used】- Suitable for a variety of science lab, chemical experimental situations.
