- About Us
Zinc
Zinc (Zn) is a bluish-white, lustrous transition metal known for its moderate strength, excellent corrosion resistance, and good thermal and electrical conductivity. It has a melting point of 419.5 °C and is widely used as a protective coating for steel and iron via galvanization. Zinc forms a stable oxide layer that helps prevent further corrosion. It is primarily obtained from zinc sulfide ores like sphalerite.
Goodfellow’s selection of zinc products, including Zinc Foil, Zinc Powder, Zinc Pellets, and Zinc Rods, is integral to a wide range of applications in industries like electronics, materials science, and corrosion protection. Zinc is commonly used in galvanizing processes, ensuring steel and iron products are resistant to rust. It is also utilized in battery technology, particularly in zinc-based rechargeable cells, and in environmental research due to its catalytic properties. Our Zinc Shots and Zinc Sputtering Targets are highly sought after by laboratory researchers in fields such as metallurgy, electronics, and energy storage.
