When you require Tungsten Heavy Alloys (WHA), make EFINEA your primary source. Since 1965, we have supplied high-quality special purpose metals and alloys while providing the highest level of service, competitive pricing and on-time delivery to our customers throughout the world. Below is an outline of the Tungsten Heavy Alloys (WHA) products we supply. Our Tungsten Alloys rods are stocked in a variety of densities and meet the ASTM B777-15 standard.
Since WHA is produced by powder metallurgy techniques, components, parts and shapes are often custom manufactured to customer specifications. We ask that you call us at 800-348-6268 about our in-stock WHA round bar, as well as the production of your Tungsten Alloy blanks, components, parts, and shapes. All stock orders are available to ship within 24-hrs of order confirmation, and materials are professionally packaged to ensure your order arrives damage free. Materials are certified with shipment and no order is too small.

Tungsten Heavy Alloys Parts, Plates, Shapes and Sheets Sizes
Since Tungsten has the highest melting point of all metals (6180°F/3420°C), casting Tungsten Alloy components or parts is not possible. Therefore, Tungsten Alloys are produced by powder metallurgy techniques which provides customers many cost saving benefits. For instance, single pieces, small batch quantity parts, components, or shapes can be produced at near-net sizes minimizing the machining required and reducing the waste material lost during the machining process. Often it is more economical and efficient to produce a series of smaller parts instead of one large part that can then be assembled into a larger unit by press fitting, mechanical fastening, brazing, etc. For complex parts or where close tolerances must be met, a blank is often produced to near-net size either in the die design stage, or by cutting the blank during the pre-sintered state, minimizing machining and material costs. Call the EFINEA sales team today with your part requirements, diagrams or schematics.

Tungsten Heavy Alloys Description
Pure Tungsten powder is combined with select elements such as Nickel, Copper or Iron to produce Tungsten Heavy Alloys (WHA). This powder metallurgy process of pressing and liquid phase sintering of Tungsten with these elements results in four classes of Tungsten Heavy Alloys. The four classes are distinguished in ASTM B777-15 by their final density which is based on the nominal percentage of 90% to 97% Tungsten powder. Classes one, two and three are available in magnetic or non-magnetic composition and class four is available in magnetic composition only. The magnetic variations use Iron as the binder while Copper is used for non-magnetic compositions. Tungsten Alloys are also known by their manufacturer’s trademark names of Densalloy®, Densimet®, Mallory 1000 and Fansteel 77.
