99.95% Aerospace Wolfram Tungsten Rod 7440-33-7
Tungsten rods are mainly usheatersheater, supillarspillar, feeders, and fasteners in vacuum or reducing atmosphere high-temperature furnaces. Moreover, serves as a light source in the lighting industry, an electrode in glass and tombarthite melting, and weequipmentpments.
Tungsten rods can be manufactured in random length pieces or cut to meet customers' desired lengths.
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 that 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.
