An improved golf club iron head utilizes a composite structure of two different weight densities to transfer weight from the hosel and heel to the ball-impact region of the head. The disclosed embodiment comprises the combination of a lightweight composite material in the outlying structural portions of the head and a metallic insert to form the majority of the face, the sole and a backweight to improve weight distribution, utilization of material mass and control of the location of the center of gravity.
