The disclosed invention comprises a novel golf club head and method of manufacturing the golf club head. The golf club head comprises a multilayer construction having a soft nickel alloy core and a hard chrome coating. The process used to produce the golf club heads involves an investment casting process in which the soft nickel alloy core is cast and the hard chrome coating is plated to the core. This multilayer design produces a golf club iron that is durable and consistent from iron to iron with feel characteristics which are generally equal to or better than traditional clubs formed from forged mild carbon steel.
