Tungsten rod Availability
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: 2.0mm~100mm diameter Length: 50-2000mm
