which is the expensive metal in the world
The Most Expensive Metal In The World. If you think gold, or silver are the most expensive metals in the world because we call them âpreciousâ, you are wrong. For starters, other precious metals like platinum and rhodium cost more despite the fact that their prices came down considerably in recent weeks.
Molybdenum as one of the most expensive metals is a Group 6 chemical element with the symbol Mo and atomic number 42. The free element, which is a silvery metal, has the sixth-highestmelting point of any element. It readily forms hard, stable carbides, and for this reason it is often used in high-strength steel alloys.
Osmium is a chemical element with the symbol Os and atomic number 76. This most expensive metals is a hard, brittle, blue-gray or blue-black transition metal in the platinum family and is the densest natural element, with a density of 22.59 g/cm3 (slightly greater than that of iridium and twice that of lead).
