Detailed Description

 Gallium is a soft silvery metal and is a brittle solid at low temperatures. It is one of three elements that occur naturally as a liquid at room temperature, The other two are liquid Hg and cesium, and it easily alloys with many metals, the alloy - galinstan (68.5% gallium, 21.5% indium, and 10% tin) has an even lower melting point of −19°C (−2 °F), well below the freezing point of water. It does not exist by itself in nature and is sourced commercially from bauxite and sphalerite.


We can offer high purity Gallium with purities of 4N -7 N, Gallium Trioxide and Copper Gallium Indium Tin Alloy (any combination).
