Cutting copper and brass
Materials such as brass and copper have high thermal conductivity and a high reflection coefficient — characteristics that make them difficult to cut using the laser method. Typically, laser cutting of copper is performed using the repetitively pulsed YAG laser mode. It is possible to obtain a perfect quality surface when using materials with a thickness of less than 2mm. Laser cutting of brass gives a slightly rough surface of the end part due to burr on the lower edge, but this is easily corrected by further processing. Please note that, the thicker the sheet of copper or brass, the worse will be the quality of the end surface, requiring additional treatment.
