Abstract

Disclosed herein is an iron-type golf club head that comprises a body, made of a first material having a first density. The iron-type golf club head also comprises a weight located within the internal cavity. The iron-type golf club head further comprises a filler material that has a density no less than 0.21 g/cc. The filler material has a mass no less than 2.5 grams and no more than 8 grams. The internal cavity has an internal cavity volume ranging between 5 cc to 20 cc. A ratio of the internal cavity volume to external club head volume ranges between 0.14 and 0.385. The internal cavity has a minimum front-to-back depth above a midplane of the golf club head of no less than 1.4 mm and a maximum front-to-back depth of the internal cavity above the midplane of the golf club head is no more than 13 mm.
