Our Powders. Your Products.

TUNGSTEN POWDER

Tungsten Powder 1

Buffalo Tungsten produces high purity tungsten powder materials that can be used in a wide variety of commercial and industrial applications. Our rigorous quality assurance program produces powders that meet an exceptional standard of consistency and quality. We are always willing to use our decades of experience to develop materials that will provide better results for your specific applications and manufacturing processes.

In addition to the standard grades of powder described in our technical data sheets, additional processing can be done to achieve such properties as

  • Higher Density
  • Narrower Particle Size Distribution
  • Improved Flow Characteristics

Fine Tungsten Powder - C3 - C20

Fine Tungsten Powders are typically greater than 99.95% purity with average particle sizes up to 10 microns.

Applications: Electrical Contacts, Semiconductors, Additive Manufacturing, Diamond Tools, Sporting Goods, Radiation Shielding, Defense, Heavy Metal Alloys

Fine Tungsten Powder

Coarse Tungsten Powder - C40 - C80

Coarse Tungsten Powders are typically greater than 99.9% purity with average particle sizes from 10 to 50 microns. They have higher apparent density and better flow properties than Fine Tungsten Powder.

Applications: Radiation Shielding, Diamond Tools, Abrasives

Crystalline Powder - C100 - C130

Crystalline Tungsten Powders are larger than the range of the Fisher Sub-Sieve Sizer, so they are classified by mesh size. They have high apparent densities and a more granular structure.

Applications: Energetics, Diamond Tools, Semiconductors, additive Manufacturing, Surface Coatings, Sporting Goods

Crystalline Tungsten Powder

Ultra High Purity - 5N

Ultra High Purity Tungsten Powders are typically greater than 99.999% in tungsten content. Impurity analyses are performed by EAG labs using GDMS method for accurate low level results.

Applications: Semiconductors, Sputtering Targets, Thin Film Deposition

Ultra High Purity Tungsten Powder

High Density - SR and ST

The High Density Tungsten Powders in our SR and ST lines have apparent densities above 130 g/in3 and a minimum purity of 99.9%.

Applications: Radiation Shielding, Plastic Compounding

High Density Tungsten Powder

Low Grade - WS and WST

WS powders are a second grade tungsten powder specifically for non-sintering applications where the high density of tungsten is desired yet extreme purity is not required. WST powder has a larger particle size with higher density.

Applications: Radiation Shielding, Plastic Compounding

Low Grade Tungsten Powder

Granulated Tungsten - GW

Granulated Tungsten is an extra large sized tungsten material made from the crushing of sintered tungsten metal which is classified by coarse mesh sizes.  Custom mesh screenings are available.

Applications: Hard Facing

Granulated Tungsten

ENGINEERED POWDER

Buffalo Tungsten produces engineered tungsten materials that contain additives of other metals in order to provide the necessary properties in your products.

Matrix Powders - WCS and WX

Matrix powders comprise a wide variety of powder types and powder sizes. WCS powders blend various metal additives with tungsten carbide powder based on customer needs while our WX powders are partially sintered mixtures of tungsten with a metal binder such as iron or nickel.

Applications: Infiltration

Matrix Tungsten Powder

Co-Reduced Powder - DNC and DNF

Co-Reduced Tungsten Powder is made by the addition of metal powders to the tungsten oxide prior to the reduction process, resulting in higher green strength. Common additives are nickel, copper and iron in any amounts.

Applications: Heavy Metal Alloys
