Pure Tungsten

Eagle Alloys Corporation can supply commercially pure unalloyed Tungsten in a wide variety of sizes and shapes for immediate shipping or we can supply custom sizes, shapes and finished parts with a short lead time.  Eagle Alloys Corporation is capable of supplying raw material or finished parts to our customer’s specifications.

EA Tungsten is DFARS Compliant since Tungsten is not listed as a specialty metal and therefore not subject to the qualifying country clause.

Eagle Alloys supplies DRC Conflict Free material only.

Tungsten has the highest melting point of the refractory metals, high density, and low coefficient of thermal expansion.  It offers exceptionally high strength and good electrical resistivity at very high temperatures.   Unalloyed Tungsten is very difficult to machine and fabricate.  Eagle Alloys can furnish finished parts in this material in relatively quick turnaround times.  We can also supply 1%, 1.5%, 2% Lanthanated, 1%, 2%, 3%, 4% Thoriated Tungsten and Tungsten Rhenium Alloys.

Tungsten Forms Available
Tungsten wire, tungsten rod, tungsten bar, tungsten strip, tungsten foil, tungsten sheet, tungsten plate, tungsten tubing, tungsten blanks, tungsten semi-finished and custom finished tungsten parts.
