Metal forging is a process of hardening, reducing the plasticity and malleability of metals by quenching, drawing or hammering them under high pressure. The metal is cooled in shape after it has been drawn into shape. The metal forging process can be done manually or with machines
Malleable metals are those that melt at relatively low temperatures, such as aluminium and zinc. These metals can be forged into almost any shape by heating them to extreme temperatures and then hammering them while they are still warm
Plasticity is the ability of a material to flow under stress, such as when bending or stretching it. Metals have little plasticity and therefore must be hardened through annealing before being forged. Annealing is a thermal treatment that softens the metal without changing its physical properties (such as hardness).
