In this research work, copper (Cu)–ZrB2 nano-composites were synthesized with different weight percentages of ZrB2 by double pressing double sintering method. The nano size of ZrB2 were distributed in the powder Cu by ball milling with ZrO2 balls in which the size of ZrB2 is < 20 nanometers and the amount of ZrB2 particles varies between 0 and 12% of the mixture. Particles were fully distributed and pressed, and the pressed pellets were sintered both, in an Ar atmosphere of tube furnace at 650 °C and microwave oven. Microwave sintering process allows us to reduce the sintering time by 16 min. Study on the nano-composite microstructures showed that the reinforcing particles were uniformly distributed in the matrix. The Cu–ZrB2 nano-composite samples were characterized using micro-hardness, X-ray diffraction analysis, scanning electron microcopy, abrasion, compressive strength and flexural strength tests. An increase in the percentage of ZrB2 nanoparticle led to an improvement in the mechanical properties of the product. The optimum amount of the reinforcing ZrB2 was determined to be 10% of the mixture.
