Abstract
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 metal material selected from the group consisting of magnesium alloys, aluminum alloys, magnesium and aluminum. A plating layer (300) is disposed on at least a portion of the aft-body (61). The plating layer (300) preferably comprises a nickel or nickel-based alloy material. The club head (42) preferably has a volume in the range of 290 cubic centimeters to 600 cubic centimeters.
