*Forging is a manufacturing process involving the shaping of metal using localized compressive forces.
Forged aluminum parts are stronger than a part machined by a solid block of the same material. The reason for this is that a forged part has been strain hardened through repeated impact force. Forging allows for preferential grain direction to occur as well as a refined grain boundary which leads to precipitation hardening.
