Product Introduction
Zinc (CAS 7440-66-6), with the chemical symbol Zn, is a bluish-white, lustrous transition metal. It is the fourth most common metal in use today. Zinc (CAS 7440-66-6) is highly valued for its exceptional anti-corrosion properties and its ability to act as a sacrificial anode. Chemfine provides Zinc in various physical forms tailored to industrial needs, from Special High Grade (SHG) ingots for smelting to ultra-fine zinc dust for high-performance coatings and chemical synthesis.

Applications
Galvanizing Industry The primary use of Zinc is to protect steel and iron from rusting. It is used in hot-dip galvanizing, electro-galvanizing, and continuous galvanizing of sheet metal.
Chemical Industry & Organic Synthesis Zinc powder is a fundamental reducing agent used in the manufacture of dyes, pharmaceutical intermediates (such as in Clemmensen reduction), and fine chemicals.
Battery Manufacturing Essential for the production of alkaline batteries, zinc-carbon batteries, and advanced zinc-air fuel cells, where it serves as the anode material.
Alloying (Brass and Die-Casting) Zinc is a major component of Brass (with copper) and Zamak alloys used in automotive parts, hardware, and electrical components.
Zinc-Rich Coatings Finely atomized zinc dust is a key ingredient in protective paints for bridges, ships, and offshore platforms, providing electrochemical protection.
Hydrometallurgy Used in the “Merrill-Crowe” process for the precipitation of precious metals (gold and silver) from cyanide solutions.
Packaging
Standard industrial packaging options for Zinc include:
-
Ingots: 20kg – 25kg ingots, bundled on 1-ton pallets.
-
Powder/Dust: 25kg or 50kg steel drums with inner PE bags (moisture-proof).
-
Bulk Powder: 500kg or 1000kg bulk bags for large-scale chemical production.
-
All powder packaging is strictly sealed to prevent oxidation and moisture contact.
Storage
Zinc powder/dust is flammable and can release hydrogen gas upon contact with moisture. It must be stored in a cool, dry, and well-ventilated warehouse. Keep containers tightly sealed and away from heat, sparks, open flames, and moisture. Store away from acids, strong bases, and oxidizing agents. For ingots, ensure storage in a dry area to prevent surface oxidation (white rust). Properly stored, Zinc has a very long shelf life, though powder should be used within 12-24 months for optimal reactivity.
