BALL BAT INCLUDING MULTIPLE ALLOYS

摘要

A ball bat includes a barrel section welded, adhered, or mechanically affixed to a handle section at a joint positioned in a taper region of the bat. The joint may alternatively be positioned in other regions, such as in the barrel region or the handle region. The barrel section may include a different metal alloy than the handle section. For example, the barrel section may include 6061 aluminum alloy and the handle section may include 7050 aluminum alloy. In some embodiments, the welded joint may be formed from a spin-welding process. The bat provides a strong handle in combination with a barrel that meets BBCOR or other performance requirements.
