Spherical Tungsten Nickel Iron (WNiFe) Alloy Powder is a ternary high specific gravity tungsten alloy with tungsten as the base, adding the appropriate amount of nickel and iron, the tungsten content is about 90%~98%, while the mass ratio of nickel to iron is usually 7:3 or 1:1. common alloys are 90WNiFe, 95WNiFe, and 97WNiFe

Our WNiFe alloy powders have uniform composition, concentrated particle size distribution (15‑53μm), high sphericity, and low oxygen content (O≤ 300 ppm). It can meet the requirements of the 3D printing (additive manufacturing) process.

We can also provide related pure molybdenum spherical powder, pure tungsten spherical powder, etc.

Spherical Tungsten Nickel Iron Alloy Powder Particle Size

5-25μm, 15-45μm, 15-53μm, 45-75μm, 45-105μm, 75-150μm. Various granularity can be customized according to customer requirements.
