Metallic Molybdenum

It is the element with one of the highest melting temperatures. Unlike most other high melting point metals, its density is only 25% higher than iron. Thermal expansion coefficient is the lowest level of engineering materials, it is one of the elements with the highest thermal conductivity.

When molybdenum is added to steel and cast irons, it increases strength, hardenability, weldability, toughness, high temperature resistance and corrosion resistance. In nickel-based alloys, it increases the resistance to both corrosion and high temperature creep deformation.
