Nov 29 , 2021laser engraving Silver and Gold
Precious metals like silver and gold are very soft. Silver is a tricky material to mark as it oxidizes and tarnishes easily. Gold can be very easy to mark, requiring little power to get a good, contrasting anneal.
Each and every RMI Laser series is capable of marking on silver and gold and the ideal system for your application depends on your marking requirements. Because of the value of these substrates, engraving and etching are not common. Annealing allows the surface oxidation to create contrast, removing only a negligible amount of material.
