Copper is hard to cut in laser cutting.Because in general copper has higher heat reflectivity,lower laser absorption,and copper also has higher heat diffusion coefficient.Using CO2 laser can’t cut copper.Brass below 1mm thickness may be cut by nitrogen gas.Copper blow 2 mm thickness can be cut only by oxygen gas.
Plastic, including acrylic, can be laser marked, engraved and cut to controllable depths while maintaining tight tolerances. Some plastics are designed to work specifically with CO2 lasers to achieve optimum results.Plastic Types: Acrylic, ABS, laminated plastics, film, polycarbonate, polypropylene, nylon and more.
Cut varying thicknesses of acrylic, engravers plastic and other plastic materials with extreme precision. Laser cutting creates a beautifully finished, clean edge on plastics.
