Al-Ca alloys are known for their low Young’s Modulus as they contain Al4Ca. While as the demand for low rigidity materials is limited, properties and production methods of Al-Ca alloys have not been well studied.
Al-Ca alloys have low Young’s Modulus, but also low strength. A small amount of Fe addition into an Al-Ca alloy does not inhibit the formation of Al4Ca, so Young’s Modulus remains low. In this work, in order to achieve low Young’s Modulus and higher strength, an Al-Ca alloy with Fe addition was prepared by Direct-Chill casting, extrusion and rolling, microstructure and mechanical properties were researched after every process. After extrusion and rolling processes, strength of the alloy could be increased, but Young’s Modulus was also increased. As a result, by adding heat treatment after extrusion and rolling, an Al-Ca alloy with increased strength and low Young’s Modulus of less than 55 GPa was successfully developed.
