In this paper, Cu/AlMgB14 composites with by weight percent, 5, 10 and 20?% of the AlMgB14 (referred to CA-5, CA-10 and CA-20) were fabricated by hot-press sintering method. The mechanical and dry-sliding tribological properties of the three composites were investigated. The results indicated that the densities of the Cu/AlMgB14 composites were lower than copper, whereas the hardness higher. The friction and wear behaviors of the composites were strongly dependent on the AlMgB14 content. The friction coefficient was in the range of 0.73-.0 for CA-5, but it was always steady at about 0.2 for CA-10 and CA-20. Accordingly, the increase in the AlMgB14 concentration can improve the wear resistance of the composites.
