Can I engrave metal with CO2 laser？

A CO2 laser cutter can engrave wood, plastic, and metals, including stainless steel. However, a CO2 laser cannot engrave the metal directly as the laser beam reflects from the surface. In order to engrave stainless steel, the material must first be pre-treated with a marking solution such as CerMark or LaserBond.

What can a CO2 laser cut？

• 20W~30 W can cut 3-4 mm with 1-3 passes before charring begins.

• ~40 W cuts 5-6 mm with 1-3 passes.

• 50-60 W will easily cut 10 mm with 1-3 passes and can cut denser woods.

• 75-120 W cuts 13 mm with 1-3 passes but starts to leave a noticeable kerf angle.
