View Patent ↗A golf club ( 40 ) having a club head ( 42 ) with a face component ( 60 ) and an aft body ( 61 ) is disclosed herein. The face component ( 60 ) has a striking plate portion ( 72 ) and a return portion ( 74 ). The aft-body ( 61 ) is composed of a crown portion ( 62 ), a sole portion ( 64 ) and optionally a ribbon section ( 90 ). The face component ( 60 ) is composed of a metal material, and the aft-body ( 61 ) is composed of a non-metal material such as a composite material or a thermoplastic material. The striking plate portion ( 72 ) preferably has an aspect ratio less than 1.7. The striking plate portion ( 72 ) preferably has concentric regions of thickness with the thickness portion in the center ( 102 ). The club head ( 42 ) has a volume in the range of 290 cubic centimeters to 600 cubic centimeters, a weight in the range of 165 grams to 300 grams, and a striking plate portion ( 72 ) surface area in the range of 4.00 square inches to 7.50 square inches. The golf club head ( 42 ) has a coefficient of restitution greater than 0.81 under test conditions such as the USGA test conditions specified pursuant to Rule 4-1e, Appendix II, of the Rules of Golf for 1998-1999.
