Many applications call for zinc in investment casting alloys. This non-ferrous metal is an important component of numerous alloys due to its natural properties and performance. Zinc, number 30 on the periodic table, is a bluish-white, lustrous metal that is malleable at 212 – 300°F, though brittle at room temperature. It is a good conductor of electricity and easy to work with in most situations. Zinc is a component of brass (along with copper) and is largely used to galvanize metals like iron to avoid corrosion. Zinc oxide ZnO is widely used in an array of products.
