W2NiB2 – Ni ternary boride cermet was studied for use as wear resistant hard materials. Microstructure configuration and mechanical properties of W2NiB2 – Ni ternary boride cermet were investigated, such as transverse rupture strength and Rockwell A hardness in different W/B ratios. The existence of W2B phase with W/B = 1.05, 1.10 samples leads the microstructure refinement. W2NiB2 – Ni ternary boride cermet showed mechanical properties of HRA86.0 in hardness, and 1.48 GPa in transverse rupture strength with W/B = 1.00 sample. W2NiB2 – Ni ternary boride cermet needs improve mechanical properties to be an alternative material to wear resistant hard materials such as WC – Co.
