Ball Construction

Core: both the used material and the core size determine the hit energy transition characteristics and influence the overall flying range of the ball. There are caoutchouc, titan, wolfram (mostly as mixes) and also liquid or plastic cores.

Cover: via its thickness, hardness and dimple pattern, the cover influences the aerodynamic drag and rotation of a ball and the feel we experience after hitting it. Covers are usually composed of two to three layers, but there are also balls with more layers.

The Ball (R & A Rules): Has a dimpled surface to reduce aerodynamic drag and can be made from a variety of materials designed to make the ball fly further, or to generate more spin. It must have a diameter of not less than 42.67 millimetres and must not weight more than 45.93 grams. There are no limits on maximum size or minimum weight.
