What is Zinc?
Zinc (CAS 7440-66-6) is a base metal supplied in refined form for industrial processing, alloying, and chemical synthesis.
Where is Zinc used?
- Galvanizing: protective coating on steel structures, automotive components, and construction materials to prevent corrosion
- Brass and die-casting alloys: automotive and electronics manufacturing where dimensional precision and conductivity are critical
- Chemical synthesis: feedstock for zinc oxide, zinc sulfate, and other compounds
- Agriculture, rubber vulcanization, and water treatment
- Electroplating and metalworking: zinc anodes and zinc-based lubricant additives for surface protection and process stability
- Zinc powder and dust serve pigment production and metallurgical applications.
Commercial specifications
- Purity grades range from standard SHG (Special High Grade, 99.995%) to high-grade and prime western grades.
- Packaging typically ranges from bulk shipments to drummed or bagged formats depending on form and end-use specification.
