近年来,随着内燃机功率的不断增大、在使用条件极力严酷的情况下,对另件的耐磨性要求越来越高。有关资料介绍:铜石墨复合材料石墨均布于基体中,石墨粒子最大间隔为1mm,石墨含量在20%(体积),抗拉强度为10kg/cm~2。铜石墨复合材料CuCr20比重7.5、拉伸强度9kg/Cm~2、延伸率3%、硬度HB60(10/500)、冲击强度0.9
In recent years, as the internal combustion engine power continues to increase, in the case of extremely harsh conditions of use, the other parts of the wear resistance requirements are getting higher and higher. Relevant information: graphite graphite composite materials are uniformly distributed in the matrix graphite particles maximum spacing of 1mm, graphite content of 20% (volume), the tensile strength of 10kg / cm ~ 2. Copper-graphite composite material CuCr20 specific gravity 7.5, tensile strength 9kg / Cm ~ 2, elongation 3%, hardness HB60 (10/500), impact strength 0.9
