▎ 摘　　要

NOVELTY - The golf club head has a structure (20) that comprises a striking face section, a sole section (22), and a top section and defining a hollow interior. The structure is cast from a combination material comprising titanium alloy and a graphene material. The graphene material comprises no more than 2.0% by weight of the combination material. The graphene material is selected from the group consisting of graphene and graphene oxide. USE - Golf club head for playing golf. ADVANTAGE - The graphene material is selected from the group consisting of graphene and graphene oxide. A crown section is comprised of the return section and a crown insert that is placed over the upper opening to enclose the hollow interior. Graphene improves the mechanical properties of the titanium alloy from which the golf club structure is cast, particularly tensile strength, yield strength, and elongation. DESCRIPTION OF DRAWING(S) - The drawing shows a plan view of the golf club head. Sructure (20) Sole selection (22) Hosel (24) Aft end (28)
