Tungsten rod is manufactured as random length pieces or cut to customers' desired lengths in diameters ranging from 0.5mm to 100mm.
In addition, there are three different surface processes or finishes which are provided, depending upon the desired end use.

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's unique properties, 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.
