AN IRON TYPE GOLF CLUB HEAD

摘要

An iron type golf club head comprising a composite material of light metal or synthetic resin containing silicon carbide whiskers at 2 to 80% by volume and occupying 20% or more by volume of the body of the club head. The club head can be 10 to 60% lighter than a club head made entirely of steel with the same configuration and size, while the moment of inertia is approximately the same. Weight metal inserts having a specific gravity greater than steel can also be embedded in the club head.
