We form Steel

Unalloyed and low-alloy steels with a maximum carbon content of 0.5% are particularly suitable for the cold extrusion process. Materials with a low tendency to harden and high formability provide good conditions for forming. Low-carbon structural steels with a carbon content of up to 0.25% are particularly suitable.

For materials with higher strength requirements, tempered steels with alloying elements such as manganese (<2%), chromium (<2%), molybdenum (<0.4%) and additions of nickel and vanadium are used. These are heat treated after the forming process to meet the required strength specifications.

Due to the continuous efforts towards lightweight construction in the automotive sector, aluminum alloys are increasingly becoming the focus for forming technology. Wrought aluminum alloys are primarily suitable for forming components. Alloying elements such as magnesium, silicon, copper, zinc, nickel and manganese can be added to adjust the application-specific properties of the formed aluminum. By adding these elements, for example, enormous strength increases can be achieved with a slight impairment of formability. In addition, further increases in strength can be achieved through precipitation hardening alloys (e.g. aluminum alloys from groups AA 6xxx and AA 7xxx).
