Tungsten Rods

Tungsten rod is manufactured as random length pieces or cut to customers' desired lengths. Standard diameter and length tolerances are listed as follows. Other, closer tolerances can be quoted on request. In addition, there are three different surface processes or finishes which are provided, depending upon the desired end use.

Quantity:
  • FOTMA

Tungsten's unique properties as a high performance material, including a melting point of 3410' C, low vapor pressure at elevated temperatures and low coefficient of thermal expansion, make it of value in a variety of high temperature products and processes. Among them are glass-to-metal seal parts and support parts for lighting and electronics, silicon rectifier stud mounts and high temperature furnace components.

Tungsten rod is manufactured as random length pieces or cut to customers' desired lengths. Standard diameter and length tolerances are listed as follows. Other, closer tolerances can be quoted on request. In addition, there are three different surface processes or finishes which are provided, depending upon the desired end use.

Tungsten rod Surface Finish
Black - Surface is "as swaged" or "as drawn"; retaining a coating of processing lubricants and oxides.
Cleaned - Surface is chemically cleaned to remove all lubricants and oxides.
Ground - Surface is centerless ground to remove all coating and to achieve precise diameter control.

Tungsten content: 99.95% 
Size: 5.0mm~100mm diameter 
Surface: Sintering surface, Forged surface, Ground surface 
Length: 50-1000mm 

Application: The Tungsten Bar can be widely used in illumination, heater and the electronic mechanical engineering, etc. The tungsten rod can be used in making the electricity photo source, the automobile and the tractor light bulb, make lattice side rod, framework, leading wire, electrode, heater and contact materials and so on.
