Molybdenum Learn How To Trade It At Commoditycom

Molybdenum is a solid shiny silvery metallic element that is ductile and malleable. It does not occur naturally as a free metal but usually in an ore known as molybdenite. Molybdenum has a very high melting point which enables it to form strong stable carbon compounds in alloys such as steel. As a result it is an important industrial element
