Application:Tungsten bar is mainly used to found ingredient of material, cutter and heads, tungsten wire for lights instruments and conductor of heat, crankshaft and cylinder barrel of advanced automobile, ingredient of kinds of heat-resistant steel. These products are mainly used for making finished tungsten wire, rods and plates and additives for precision alloy.

 

We prepare our tungsten to perform perfectly in its specific applications. We can determine the following properties through the addition of various alloys: 
 -  Physical properties (e.g. melting point, vapor pressure, density, electrical conductivity, thermal conductivity, thermal expansion, heat capacity, electron work function) 
-  Mechanical properties (e.g. strength, fracture behavior, creep resistance, ductility) 
-  Chemical properties (corrosion resistance, etchability) 
-  Workability (e.g. machining, formability, weldability) 
-  Microstructure and recrystallization behavior (recrystallization temperature, embrittlement, aging effects)   
  

We supply tungsten wire, tungsten bar, tungsten plate, tungsten sheet, tungsten rod, tungsten electrode, tungsten fabricated parts, tungsten alloy, tungsten copper alloy, tungsten heavy alloy.
