Ed Fagan is a leading distributor and manufacturer of high-density Tungsten Heavy Metal Alloys (ASTM B777-15). Tungsten Heavy Alloys (WHA) are produced by powder metallurgy techniques. A range of Tungsten powder between 90% and 97% (depending on the final density required) is mixed with nominal amounts of Nickel, Copper or Iron elements and then compressed. The final phase, liquid sintering, results in four classes of high-density, machinable Tungsten-Nickel-Iron or Tungsten-Nickel-Copper Alloys with unique physical properties, as well as magnetic and non-magnetic compositions.
Overall WHA exhibit extremely useful property benefits such as, high tensile strength, good ductility and hardness. Twice as heavy as Steel and approximately 50% denser than Lead, these alloys are utilized where a concentrated mass is required in a limited space. Tungsten Alloys are relatively easy to machine and can be plated or painted to enhance their corrosion protection. Tungsten Alloys are also known as Densalloy®, Densimet®, Mallory 1000 and Fansteel 77.
TUNGSTEN HEAVY ALLOYS QUICK FACTS
- Alloyed with Ni & Fe, or Ni & Cu for Magnetic or Non-Magnetic Grades
- Complex Parts or Components Can Be More Efficiently Produced
- Environmentally Friendly
- High Density Range of 17.0 to 18.5 g/cc
- Superior Machinability Versus Pure Tungsten
Tungsten Heavy Alloys Forms and 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 Heavy Alloys (WHA) are produced by powder metallurgy techniques which has size limitations. Customers often provide diagrams and schematics and the parts are supplied as semi finished products, ROTF (rough oversized to finish). The powder metallurgy techniques used in the fabrication process, allows customers to have shapes and parts formed to minimize the cost of the final product.
Ed Fagan is a leading supplier of refractory metals and alloys. You can rely on our expertise to provide you with Tungsten Alloys in the forms and shapes you need. In addition, our in-house fabrication services are available to machine your order to your size and shape requirements.

Machining Tungsten Heavy Alloys
Tungsten is alloyed with different elements such as Nickel, Copper and Iron to produce a large variety of Tungsten Alloy grades. Many of these grades have engineering properties similar to Steel making them relatively easy to machine. These alloys can be drilled, milled, turned and tapped using standard tools and equipment, while using speeds and feeds similar to Grey Cast Iron.
Tungsten Heavy Alloys Applications
Ed Fagan is a leading source for industrial supply chain distribution of Heavy Metal Tungsten Alloy grades for fabrication and parts applications within various advanced technology industries. With a nominal Tungsten content range from 90% to 97% and the balance primarily of Nickel, Copper and Iron, these alloys provide unique engineering properties. They deliver greater ductility and better machinability than pure Tungsten. Tungsten Alloys can be plated or painted to enhance their corrosion protection.
