ABSTRACT:
A one-body hollow precision cast metal golf club head is fabricated by casting metal about a head core to form a shell, and melting and flowing out the head core. The head core is made of low melting point alloys having a melting point lower than that of the metal used for casting the shell and is coated with an aqueous solution prior to the casting process of the shell. The aqueous solution is a composition including inorganic powders, binders and solvent. The ratio of components should be inorganic powder:binder:solvent=(40-80):(1-10):(10-59) based on weight.
