Gallium is a by-product of aluminum extracted during the processing of bauxite into alumina. It can also occasionally be found in Zn ore. We are a refiner and supplier of gallium materials. Gallium and gallium alloys are desirable because of their low melting points and wetting properties. They are used for thin-film coatings and in thermal interface materials. Gallium is also used in many semiconducting applications, such as photovoltaics, diodes, and integrated circuits.
