Zinc Oxide Varistor, General Series Metal Oxide Varistor -
We offer a wide plethora of Zinc in many forms Special High Grade Ingots and Jumbos, cathodes, dust, foil, granules, powder, pieces, anodize activated powder, shot, and a mossy form. Zinc is a bluish-white, lustrous metal. It is brittle at ambient temperatures but is malleable at 100 to 150 C. It is a reasonable conductor of electricity, and burns in air at high red heat with evolution of white clouds of the oxide. Plating thin layers of zinc on to iron or steel is known as galvanizing and helps to protect the iron from corrosion.
