Aluminum-Alloyed Cast Iron as a Versatile Alloy

Abstract

The feasibility of intelligent utilization of iron-aluminum scraps is explored in this work. Through adding aluminum which is contained in the scraps to cast iron, the changes in wear resistance, heat resistance and damping property of aluminum-alloyed cast irons were systematically investigated. Superior properties were obviously manifested in the cast irons with certain aluminum contents. Iron-aluminum mixed scraps are expected to be utilized as a raw material for high quality cast irons.
