The research in Copper based friction materials has been focused on the effect of material composition on its physical, mechanical and tribological characteristics, however the information on the improvement of composition which composed of copper, iron-oxide and graphite on the Copper based friction materials. three samples composed of copper, iron-oxide and graphite were fabricated through powder metallurgy process. among the assessment were porosity, hardness and he tribological test which follow the international standard test procedure. test results shows that the A3 sample with the highest volume of copper percentage produces the highest porosity compared to the other test samples. Sample A3 also produced higher and stable coefficient of friction (COF) at the lowest weight loss. based on current findings, it can be concluded that the sample A# which composed of 85% of copper is the best formulation which can be replace the available commercial carbon as it produces a higher COF and lowest weight loss.
