COMMENTS
The manufacturing processes for coated brass varies from one vendor to another. Some manufacturers do not polish the brass before coating it. Since CO2 lasers at this power level do not engrave into metals when the coating is removed, the tarnished brass underneath will have a dull appearance that will need to be polished with a brass polishing compound. This type of brass is designed for mechanical engravers that actually remove the metal when engraving which gives the brass a shine without polishing. Brass that is produced for the laser engraving industry is polished, then clear coated, and finally coated with paint. When laser engraving this type of material, adjust the power so that the laser beam removes the painted coating but not the clear coating. This will expose the polished,
DO NOT ATTEMPT TO ENGRAVE DEEPLY OR CUT THIS MATERIAL WITH THE LASER SYSTEM. High Power and low Speed settings can cause the laser beam to reflect off of this material which can damage the laser system and can be a safety hazard. Damage caused by this type of abuse WILL NOT be covered under warranty.
