Tungsten rod Availability

Tungsten rod is manufactured as random length pieces or cut to customers' desired lengths.

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 - The surface is chemically cleaned to remove all lubricants and oxides.

Ground - The surface is centerless ground to remove all coating and to achieve precise diameter control.
