Molybdenum and tungsten for furnace construction

Tungsten and molybdenum are refractory metals and are suitable for applications at extreme temperatures, unlike other materials. These metals have unique properties, which make them an ideal option for components employed in the furnace construction industry. These metals have excellent creep resistance, superior dimensional stability, high melting points that allow operating temperatures of up to 2800°C. They have a low coefficient of thermal expansion and an excellent corrosion resistance.

Molybdenum or Tungsten are the ideal choice when you need to achieve long life at high temperatures in a vacuum furnace. These materials operate trouble-free at high temperatures for years and low vapor pressure allows them to be used in a vacuum.

Pure Molybdenum can heat furnaces to 1900 °C, and tungsten is used as heating elements in electric furnaces which must withstand high temperatures. 

Tantalum for furnace construction

The high melting point and oxidation resistance lead to the use of tantalum in the production of vacuum furnace parts. Tantalum and tantalum-based alloys retain their strength at high temperatures (tantalum has a melting point around 3000 °C), that is why they can be used in such high-temperature applications as furnace parts and for cladding the interior of combustion chambers. Tantalum metal is also used for sintering tray assemblies and shielding components for the anode sintering furnaces
