Our tungsten heavy alloys give you many of the benefits of pure tungsten with improved machining capabilities. These alloys come in a range of stock shapes and are ideal for use in high-density applications or for radiation shielding. We stock a range of alloys from 90% to 97% pure tungsten in a matrix of nickel/copper or nickel/iron. 

Look at our rod, bar, sheet, and plate options. We can provide custom sizes not in stock and have an in-house machine shop to produce your final products to your specifications. 

The alloys below are in stock. Other alloys can be custom made.

MT-17C: (-0/+0.003" dia) (-0 length) 17g/cc density. 90% Tungsten, 6% Nickel, 4% Copper. High quality tungsten heavy alloy (W) rod in 12" lengths conforms to international standard ASTM B777, Grade 1, Type II & III. You will receive a complimentary material cert in the safely packaged shipment. All material is lot controlled, stress relieved, and formed through high temperature pressing and sintering processes.
