Refractory Metals

 


Chemical composition, mechanical and physical properties about production of refractory metals.
 

Molybdenum / TZM

 

Molybdenum has similar properties to tungsten but with much better machinability which gives it wider application.

TZM (Titanium-Zirkonium-Molybdenum) a molydenum base alloy, primarily created for high temperature applications. TZM has a higher recristallisation temperature, higher tensile strength than pure molybdenum.

Application
High temperature furnace construction: Heating elements, heat shields, sample supports, common structural parts
Sintering technique: Sinter boats, transport installations
Evaporation technique: Evaporant boats
Glas manufacturing: Electrodes for all-electric and electric boosted glass melting furnaces
Semi-conductor production: Discs, furnace parts for single-crystal fabrication

         

Tungsten

 

Tungsten (Pure Tungsten and Tungsten base material) as pure metal with the highest melting point of all metals and very high density.

Application
Evaporation technique: Filaments and boats from pure tungsten
High temperature vacuum furnace construction: Furnace parts and heating elements
Protective gas welding technique: Tungsten electrodes WP, WT 10-40, WZ4, WZ8, WL 10-20, WC20, WV15
X-ray technique: Radiation shields from heavy metal "High Density"
Resistance heating: Upset-forging anvil-electrodes from heavy metal "High Density"
CuCrZr electrodes with WL10 inserts
Common machine-building industry: Construction parts
Electrical engineering: Switch contacts from tungsten copper
Spark machining: Electrodes from tungsten copper

 

Tantalum

 

Tantalum is used for chemical devices because of its outstanding properties: high chemical resistance and good machinability.

Application
Evaporation technique: Evaporant boats
Electrical vacuum furnace construction: Heat shields
Chemical industry: Parts and liners giving projetion against extreme corrosion
