Molybdenum pure

[Mo pure 99.95 %]

Molybdenum is a refractory metal with a high melting point. Compared to tungsten, it is more malleable and easier to machine even at low temperatures. The maximum application temperature is approx. 1,900 °C; tungsten is generally used above this temperature. Typical applications range from heating elements and furnace components to evaporator sources and sputtering targets to wires/strips for lighting technology and components for glass and metal melting.
