Coated or painted metals have always been easily engraved with a CO2 Laser, provided there is a contrast in color between the outer and underneath colors. Anodized aluminum products have always been a popular material for a CO2 LASER because the laser bleaches the pigment, giving it a nice contrasted mark, without interfering with the anodization process. Additionally, thanks to a product by Ferro Corp., laser engraving on bare metals is now possible, using a CO2 laser. LMM6000 is a chemical comprised of a molybdenum trioxide and other additives, which is applied to bare metal surfaces, prior to engraving. Once dry, the material adheres itself to the metal, and can then be laser engraved with a C02 laser. Results will vary depending on the metal and the desired affect, but dark indelible marks are possible using this method. Once lasered, the excess will wash off with water. While this method does not work for all metal projects, it does give engravers another option. For more information about this product, contact Ferro directly at 724-250-5503 or Laserbits, Inc. 602-943-1228, who distributes the product.
