It is well known that luxury and sports cars use real magnesium wheels (contain more than 90% pure magnesium). The use of magnesium wheels is required for performance improvement, mainly in the steering system.
Reduction of mass aroung the wheel axis may affect significantly the vehicle stability.

In order to keep mechanical properties and to save weight, a hot forging process is carried out. the most used magnesium alloy for forging is ZK60A in T5 temper. the process is completed by shear spinning process followed by 3D machining in order to get final shape.

Many aeronautical parts of civil aircraft, helicopters, jet engines and missiles are manufactured by forging technology in closed dies. Generally out of aluminum alloy ingots - 6061, 6066, 6063, 2618, 2024, 7051 - suitable for thermal treatments.
Designers choose forging process when there is a need to keep mechanical properties during plastic deformation of a solid state. As far as the forging process is more accurate and approached to the net shape, less material is wasted. Furthermore, the forging process is relatively fast so the work being invested is much smaller than a full machining process.
Considering cylindrical-symmetric part, stress flow during professional upset forging can improve strength through tangential direction (see picture on the right).

The accumulative experience in the plastic deformation phenomenon of the HCP structure, provides AMTS technologists to implement the upset the forging processes.

While using several conventional magnesium alloys such as: AZ80A, ZK60A, AZ31B, we are able to operate the complete process in medium scale part geometries (see samples). In order to achieve the accurate final shape, the upset forging, which is carried out in closed dies, is usually followed by very fine machining process.

Additional works are carried out using new magnesium alloys and magnesium matrix materials.
