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 rod application
The tungsten rod 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, contact materials and so on.
