Cu/AlMgB₁₄ composites with different AlMgB₁₄ amounts were fabricated by hot press sintering. The influences of the sintering temperature and the AlMgB₁₄ content on the tribological and mechanical properties of the composites were preliminarily investigated. In short, a lower sintering temperature leads to a lower friction coefficient but relatively poor mechanical properties, while the opposite results are shown at higher sintering temperature. Besides, raising the AlMgB₁₄ concentration to some extent can markedly reduce the friction coefficient and the wear rate of the composites. Especially when sintered at lower temperature, the composites with 10 wt% AlMgB₁₄ or above have the lowest friction coefficient of 0.2.
