## Abstract
This study aims to determine the wear resistance and hardness of aluminum matrix composites (AMCs) plus SiC amplifier with a ratio of 98% Al-Si and 2% SiC using the stir casting method. The research method is the wear test with ogoshi high-speed universal wear testing machine and hardness test with the Brinell method. Variation the pouring temperature used in the stir casting method are 688°C, 738°C, and 788°C. The wear test results at abrasion speed of 0.250 m/sec in 60 seconds, shows that the specific wear value of the compressive force is 2.12 kg which tends to be higher when compared to the specific wear value in the compressive force of 3.18 kg and 6.36 kg. The results of hardness testing showed that the addition of SiC to aluminum matrix composites (AMCs) increases the value of matrix hardness. The specimen samples without SiC addition have the lowest hardness level compared to those using the addition of 2% SiC, which is 578.01 HBW 10/3000/15.
