Cutting Nickel AlloysThe most common methods of cutting nickel alloys is by either plasma or laser. Plasma cutting can be used to cut a range of thickness from sheet to in excess of 30mm. A range of gas combinations from air, to nitrogen - carbon dioxide and argon or argon-hydrogen or argon-helium mixtures can be used. The choice of which to use is dependent on cost, type of machine being used, cut quality required and accuracy of cut. Although laser cutting is limited to much thinner cross-sections than plasma the quality of the cut face, the smaller heat affected zone and reduced distortion are all advantages of the process.
