ABSTRACT

Aluminium matrix composite is one of composite materials that has good mechanical properties and widely used in industry. The addition of Mg and SiC components increased the hardness number of the composite. While, the aluminium 6061 alloy is an alloy with the possibility of small shrinkage defects and better liquidity levels that affect the weldability and cast ability due to the silicon content of the alloy. (1) In this study the addition of Mg serves to increase the value of hardness, wetting ability of the matrix and reinforcement. (2) This study analyzed the addition of 3%, 5% 8% Mg and 8% SiC. The tests were done by hardness test, tensile test, microstructure observation, SEM, and XRD. (3) The highest hardness number was 87.67 HRB with the addition of 8% Mg while the highest tensile strength was 174.26 MPa with the addition of 5% Mg. (4) From the results of the study showed that the addition of Mg improves the mechanical properties of Al6061/SiC composites.
