The inner tubular portion includes a metal matrix composite formed of a compact impregnated with an Al—Si alloy wherein the compact is made of a reinforcing material. The outer tubular portion is formed of the Al—Si alloy. The Si concentration of the Al—Si alloy impregnated into the compact of the inner tubular portion is different from the Si concentration of the Al—Si alloy of the outer tubular portion.
