Gallium Pellets

Gallium Pellets are a high purity form of gallium from Goodfellow's range of pellets. Gallium is a soft, silvery metal that melts at just above room temperature. Gallium pellets have an extremely low melting point and high thermal conductivity, making them ideal for applications like heat transfer fluids and low temperature thermometers. The non-toxic properties also allow them to be used in dental alloys. With their unique properties, Goodfellow's Gallium Pellets enable innovative applications across industries.
