Buffalo Tungsten has a sole focus on powdered tungsten materials. We don’t make finished tungsten products by sintering, compounding or additive manufacturing. We just make the tungsten raw materials that our customers use in their products.
This focus allows us to concentrate all of our efforts on improving the quality as well as the properties of our powdered tungsten materials. We refine our production parameters regularly to optimize our powders.
Types of Powdered Tungsten Materials
Our materials are classified by material composition. Although powdered tungsten is the basis, a number of materials derive from pure tungsten powder. They have unique properties that make them suitable for different applications.
To illustrate, here are the main categories of powders that we produce:
Pure Tungsten Powder – We start with tungsten oxide that undergoes hydrogen reduction in furnaces to become pure tungsten powder. This material is over 99.9% pure tungsten, with our ultra high purity powders reaching five nines at 99.999% pure.
Tungsten Carbide Powder – This is a blend of pure tungsten powder and carbon powder that runs through furnaces at high temperatures to create WC powder.
Engineered Powder – Alloys such as iron (Fe), nickel (Ni) and copper (Cu) blend with pure tungsten powder to achieve special properties in finished products. Our matrix powders are used in infiltration applications and our co-reduced powders are used in heavy metal.
Thermal Spray Powder – These surface coating powders create a protective coating with especially high density and hardness. Various compositions of tungsten carbide (WC) with cobalt (Co), chromium (Cr) and nickel (Ni) provide excellent wear properties as well as oxidation and corrosion resistance.
Our materials are all made to meet custom specifications according to customer need. They come in various particle sizes and distributions. In addition, we crush solid tungsten and tungsten carbide materials to produce granular tungsten in various mesh sizes. Our products can also vary in chemical composition.
