Impact extrusion is a type of specialty cold forming used for larger parts with hollow cores and thin wall thicknesses. The impact extrusion process begins with a tightly controlled, by weight, metal blank that is placed in a die that is located on a …
For starters, it's considered a cold-working process, meaning manufacturing companies don't need to heat the metal slug beforehand. The metal slug can be deformed at or near room temperature thanks to the superior power offered by the press machine. Unlike many other extrusion processes, impact extrusion only requires a single impact.
Cold forging or cold extrusion is growing popular because of the many advantages it process offers. There are many reasons manufacturers prefer cold forging over hot forging, precision forging, temperature extrusion, and so on. One of the advantages of cold forging is higher energy saving compared to other available options.

Strength and ductility. Aluminium impact extrusion can be considered as cold forging. Significant plastic deformation at room temperature results in cold work hardening due to the movement and displacements in the grain structure. This results in an increase in strength (+15%) and a simultaneous decrease in ductility.

In coaxial extrusion, or cladding, coaxial billets are extruded together provided that the strength and ductility of the two metals are compatible. An exam- ple is copper clad with silver. Stepped extrusions are produced by extruding the billet partially in one die and then in one or more larger dies (see also cold extrusion, Section 15.4).
