CO2 Metal Marking Spray with a Laser

CO2 laser machines can directly mark a variety of coated metals such as anodized aluminum or powder coated stainless steel. However, bare metals reflect the wavelength of a CO2 laser, meaning direct marking typically requires a fiber laser source. Fortunately for CO2 laser owners, there’s another great option. Bare metals like titanium or nickel plating can be pre-treated with a metal marking compound prior to engraving with a CO2 laser.

The pre-treatment process is very simple and while it will not actually remove any of the metal material, you will be left with a durable and permanent raised mark on your bare metal products. Operators simply apply the marking solution – some common products include CerMark, Enduramark, and LaserBond – allow it to dry, and then perform the engraving as normal. The heat from the laser bonds the solution to the metal, resulting in a permanent black, silver, or sparkle-type mark from a CO2 laser machine.
