Abstract
An aluminum alloy consists essentially of 90 to 99.5% by weight of matrix and 0.5 to 10% by weight of a dispersant dispersed within the matrix. The matrix comprises 10 to 25% by weight of Si, 5 to 20% by weight of Ni, 1 to 5% by weight of Cu and the rest of Al and impurity elements. The dispersant is at least one selected from the group consisting of 0.5 to 10% of nitride, boride, carbide and oxide. The aluminum alloy shows excellent tensile strength and wear resistance.
