| الملخص: | Bearing is an important component in the automotive industry that is needed to be made of
material having good properties. Aluminum graphite matrix composite becomes a selected
tribology application in self-lubricating bearing. This composite hasgood wear resistance and
low density compared with bronze bearing material so that gives more economical values. This
research is done by the method of powder metallurgy with aluminu,!, matrix composite material
using an additive of 5% graphite weight fraction. Variable compactions (P) are 400 MPa, 500
MPa, 600 MPa and sintering temperature is 55dJc, ~ith variable holding times (HT) 1 hour, 2
hours and 3 hours. The study aims to analyze the effect of graphite content affecting the
mechanical properties of aluminum graphite composite material. The test results show that the
optimum condition of 5% graphite content is the density = 5.11 gr/cm3, the hardness = 54.449
HB, the compressive strength = 790 MPa, when P = 600 MPa and lIT = 3 hours.
