Separable Materials

Originally, plasma cutting was developed for the purpose of cutting all those materials which could not be cut with oxy-fuel due to their chemical structures. This concerns primarily high-alloyed steel, aluminium and copper. Particularly due to the small heat-affected zone and high cutting speeds this process soon became accepted also for cutting mild steel.

Generally, plasma cutting can be used for cutting all electrically conductive materials. In order to achieve always optimum cutting results, the consumables and the used plasma gases have to be changed depending on the material. The further development of one process variant even showed the possibility to cut insulating materials like glass, concrete or interrupted structures with plasma (see Hot-Wire).
