Tungsten has the highest melting point of all metals as well as a remarkably high modulus of elasticity. Molybdenum also belongs to the refractory metals group with excellent thermal properties and is still easy to machine. So, tungsten, molybdenum and their alloy is the best choice for the all kinds of high temperature furnace. They can easily withstand even the most intense heat.
