N2 - W-Ni-Fe-(Cr) alloy powders was used for metal injection molding (MIM) to understand the sintering structures. The effects of Cr content and tungsten-powder particle size in mechanical properties of W-Ni-Fe-(Cr) alloy were also discussed. According to the experimental results, the volume shrinkage in W-Ni-Fe alloy increased with decreased the particle size of tungsten-powder. Even if slightly decreased the particle size of tungsten-powder that could still play an important role on raising tensile strength and matrix hardness. If added the Cr element, the tensile strength decreased but the oxidation resistance and hardness could be improved. Besides, the Cr element affected the microstructure and it's concentration was also different in composed of phases.
