Product details

ASTM B777, "Standard Specification for Tungsten-Based High-Density Metals," and AMS 7725, "Sintered High-Density Tungsten-High-Density Alloys," both define four classes of tungsten alloys that contain a nominal 90 to 97 weight percent (wt%) of tungsten (W). These four classes are pressed, sintered, and in some cases annealed to shape.

Classes 1-3 are typically divided into non-magnetic and magnetic compositions, while Class 4 is typically offered in magnetic compositions only. In addition to ASTM, Elmet offers "modified Class 2" compositions, which are 93% tungsten (W) by weight (wt%) and have some enhanced properties for certain defense applications.

We can also supply Nickel Alloys, Tungsten Alloy, Molybdenum Alloy in any form.
