Abstract

An aluminum alloy powder for sliding members includes Fe in an amount of from 0.5 to 5.0% by weight, Cu in an amount of from 0.6 to 5.0% by weight, B in an amount of from 0.1 to 2.0% by weight and the balance of Al. An aluminum alloy includes a matrix made from the aluminum alloy powder and at least one member dispersed, with respect to whole of the matrix taken 100% by weight, in the matrix, and selected from the group consisting of B in an amount of from 0.1 to 5.0% by weight, boride in an amount of from 1.0 to 15% by weight and iron compound in an amount of from 1.0 to 15% by weight, and thereby it exhibits the tensile strength of 400 MPa or more. The aluminum alloy powder and the aluminum alloy are suitable for making sliding members like valve lifters for automobiles.
