UV, CO2, and Fiber lasers are ideal for cutting perfect parts from many types of sheet metal – alloy steel, aluminum alloys, brass, carbon steel, molybdenum, stainless steel, titanium, platinum, and tool steel. Some applications include slots for stencil masks, hole orifices for gas flow restrictors, slits in optical apertures or filters, and tubular parts with specific patterns. Laser cutting greatly simplifies the design and manufacturing process to produces intricate detail and very sharp corners.
Alloy Steel and Tool Steel: Since care is taken to control the amount and distribution of additives to the base iron, most alloy steels are considered ideal candidates for the laser cutting process. High strength materials such as 4130 (chrome moly steel) and 4340 (chrome nickel moly steel) display exceptional laser cut edges that are square and clean.
Stainless Steel: High-power CO2 and Fiber lasers create dross-free edges without deburring for clean cutting of sheet metal fabricated components made from stainless. The laser process minimizes the HAZ along the cut edge, thereby helping the material to maintain its corrosion resistance. At the same time, the cut edges are smooth, clean, and square.
Titanium: Pure titanium responds well to the concentrated heat energy of a focused laser beam. The use of an oxygen assist enhances the cutting speeds but tends to promote a larger oxide layer along the cut edge.
