A zinc raw material refers to zinc ore, such as the mineral sphalerite, from which the elemental zinc is extracted and processed for industrial use. This naturally occurring mineral contains zinc sulfide (ZnS) and is mined from the Earth's crust.
| Technical Specifications of Zinc Raw Material | |
|---|---|
| Purity Grades | Different grades exist, with "Special High Grade" often having a minimum of 99.99% zinc |
| Impurities: | Specifications set limits for elements such as lead (Pb), iron (Fe), cadmium (Cd), aluminum (Al), copper (Cu), and tin (Sn) |
| Appearance: | A bluish-silvery color when oxidation is removed, though commercial grades may appear duller. |
| Density: | Approximately 7140 kg/m³. |
| Melting Point: | 419.5 °C |
| Boiling Point: | 907 °C |
| Crystal Structure: | A distorted form of hexagonal close-packing |
| Malleability: | Brittle at room temperature but becomes malleable and ductile between 100-150 °C (212-302 °F). |
| Strength & Hardness: | Pure zinc is relatively weak and brittle, but alloys like ZAMAK can offer improved strength. |
Galvanization: This is the largest use, where iron and steel are coated with a protective layer of zinc to prevent rust, used in products like roofing, fences, and automotive parts
Alloys:Zinc is a key component in alloys such as brass (with copper) and other casting alloys used in musical instruments, plumbing, and decorative items.
Die-Casting:Due to its excellent casting properties, zinc is used to create precise components for the automotive and electronics industries, as well as for items like handles, door knobs, and hardware
