Gallium
gallium
We offer Gallium ingot, Gallium metal.
Grade: 99.99% (4N).

Physical properties
Gallium is a soft, silvery metal with a shiny surface. In some ways, however, it is very un-metal-like. It is so soft that it can be cut with a knife. It has a very low melting point of only 29.7°C (85.5°F). A sample of gallium will melt if held in the human hand (body temperature, about 37°C.

Another unusual property is that gallium can be supercooled rather easily. Supercooling is the cooling of a substance below its freezing point without it becoming a solid. Gallium is a liquid at 30°C, so one would expect it to become a solid at 29.7°C. Instead it is fairly easy to cool gallium to below 29.7°C without having it solidify.

Gallium's boiling point is about 2,400°C (4,400°F) and its density is 5.9037 grams per cubic centimeter.

Chemical properties
Gallium is a fairly reactive element. It combines with most non-metals at high temperatures, and it reacts with both acids and alkalis. An alkali is a chemical with properties opposite those of an acid. Sodium hydroxide (common lye, such as Drano) and bleach are examples of alkalis.
