An improved golf club head design for irons is presented which provides a carburized tungsten alloy insert in the club face. The carburized tungsten alloy insert improves the club's center of gravity and center of mass characteristics and presents a harder surface to the golf ball, improving club face longevity. There are also improved rebound characteristics seen with the use of a carburized tungsten alloy club face insert.
