Iron golf club head

An iron golf club head comprising:

• a periphery member composed of a first metal material having a density between 8 g/cm3 and 12 g/cm3, the periphery member having a sole wall, a toe wall extending upward from the sole wall at a first end of the sole wall, a hosel extending upward from the sole wall at a second end of the sole wall, a heel wall extending upward from the sole wall, and a top wall extending from an upper end of the toe wall to an upper end of the heel wall, the top, sole, heel and toe walls of the periphery member defining an opening;
• a central member disposed in the opening of the periphery member, the central member composed of a thermoplastic polyester polyurethane having a Shore D hardness ranging from 50 to 65, the central member having a body portion with a perimeter, an interior surface, an exterior surface, a sole surface, a top surface, a toe surface, and a heel surface, the central member having at least one recess formed in the exterior surface of the body portion, the perimeter having a plurality of tabs projecting outward, the tabs engaging an interior surface of the periphery member;
• and
• a face plate composed of a second metal material, the second metal material having a lower density than the first metal material, the face plate being mounted in the opening of the periphery member and disposed over the forward surface of the central member, the face plate having a thickness between 0.040 inch and 0.250 inch.

An iron golf club head comprising:

• a periphery member composed of a nickel-tungsten alloy having a density between 9 g/cm3 and 10.5 g/cm3, the periphery member having a sole wall, a toe wall extending upward from the sole wall at a first end of the sole wall, a hosel extending upward from the sole wall at a second end of the sole wall, a heel wall extending upward from the sole wall, and a top wall extending from an upper end of the toe wall to an upper end of the heel wall, the top, sole, heel and toe walls of the periphery member defining an opening;
• a central member disposed in the opening of the periphery member, the central member composed of a thermoplastic polyester polyurethane having a Shore D hardness ranging from 50 to 65, the central member having a body portion with a perimeter, an interior surface, an exterior surface, a sole surface, a top surface, a toe surface, and a heel surface, the central member having at least one recess formed in the exterior surface of the body portion, the perimeter having a plurality of tabs projecting outward, the tabs engaging an interior surface of the periphery member;
• and
• a face plate composed of a titanium alloy, the face plate being mounted in the opening of the periphery member and disposed over the forward surface of the central member, the face plate having a thickness between 0.040 inch and 0.250 inch.
