99.95% pure. Wire is clean and straightened. All sizes are stocked for immediate delivery.

Our tungsten wire conforms to ASTM F288-96, Type 1A. It is provided clean and straightened. Standard finish is electropolished, although as-drawn finishes are available by request or in some cases, off the shelf.



Uses of this wire include:

medical devices
LEEP and LEED electrodes
corona generation
vacuum heating elements
filaments
thermionic emitters
We also provide thoriated tungsten wire, lanthanated tungsten wire, and tungsten-rhenium wire by request.

Volume discounts are available for purchases of 5 spools or more and for large quantities of self-coiled wire (.020 diameter and above). Choose single or multiple strands.

Thank you for understanding that it is not economically feasible for us to sell package sizes smaller than those listed.

Tungsten heavy alloys are ideal for high density applications or for use in radiation shielding. Heavy metal tungsten alloys are 90% to 97% pure tungsten in a matrix of nickel and copper or nickel and iron. The addition of these alloying elements improves both the ductility and machinability of these alloys over non-alloyed tungstMTS can custom machine any alloys to finished parts according to your specifications. We carry an extensive inventory of tungsten alloys and provide quick turnaround for those items not in stock. Call (1-800-626-0226) or send us a message for more information or with a specific request.

We also manufacture aircraft bucking bars and ballast weights for aircraft, high performance autos, and sailboats made of tungsten alloy.

TIG Tungsten Electrodes

Tungsten Inert Gas (TIG) welding is a popular type of welding that utilizes tungsten electrodes to join various metals. The tungsten electrode is a critical component in the process, as it channels the current required to establish the arc. The tungsten electrodes can be alloyed with a variety of metals. Different types and sizes of electrodes are used for different types of welds and materials, and welders develop preferences based on welding style and project. Certain electrode types perform better with alternating current (AC) as opposed to direct current (DC). Electrodes are shipped without a ground tip. If grinding a tip, make a tight, sharp point in order to achieve a powerful and precise arc to ensure a clean weld.

Below is a table describing the differences in TIG electrode types, and you can find the full product line at midwesttungsten.com.
