About Rhenium

Rhenium is a rare silvery metal, quite strong and the one which has the highest melting point among metals. It has got its name after the word the Rhine in Latin. This metal has no biological role and it occurs on our planet very rarely, not on its natural form but only in compounds with other chemical elements. Rhenium is used in alloys with other metals to produce very strong steels which can be used in special types of industries. In particular, the applications include X-ray machines and oven parts, turbine parts, parts of electrical devices, and so on.
