A unique golf ball and related methods of manufacturing are disclosed in which the golf ball comprises one or more metal mantle layers and a cellular or liquid core component. The metal in the mantle layer may be formed from steel, titanium, chromium, nickel, and alloys thereof. The cellular core may utilize at least one material selected from the group consisting of polybutadiene/ZDA mixtures, polyurethanes, polyolefins, ionomers, metallocenes, polycarbonates, nylons, polyesters, and polystyrenes. The golf ball may also comprise an optional polymeric spherical substrate inwardly disposed relative to the one or more metal mantle layers. The golf balls according to the present invention exhibit is improved spin, feel, and acoustic properties. Furthermore, the one or more interior metal layers prevent, or at least significantly minimize, coefficient of restitution loss from the golf ball, and significantly increases the moment of inertia of the golf ball. |
