TUNGSTEN, TUNGSTEN ALLOYS & COPPER TUNGSTEN

Pure Tungsten

DWDBRASS 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.

DWDBRASS 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. DWD 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, Tungsten Rhenium Alloys & Tungsten Carbide.
