The BBCOR one-piece bats are made of composite or metal and they are one solid piece from the barrel to the handle. The two-piece bats have separate barrels and handles. The two-piece bats usually have different materials, with a composite handle and a metal or composite barrel.
Two-piece bats generally have less vibration in the handle due to the separation of the handle and barre. Alloy vs. Composite vs. Hybrid. Alloy bats are generally constructed with a one-piece design out of aluminum or aluminum that is mixed with other metals to make a stronger product. The advantage to this strength is that it allows alloy bats can have thinner, more responsive barrel walls. Composite bats, on the other hand, are made out of a mixture of carbon fiber, graphite, fiberglass, and sometimes Kevlar. Hybrid bats feature a two-piece design in which an alloy barrel is bonded to a composite handle.
