Do you have any tips on engraving bare aluminum? Like speeds and max / min power settings? I have a Tounjen laser machine. Thanks.
Co2 lasers of this class cannot mark metals…
You can use some kind of spray that creates a molecular bond with the metal from the heat.
LBT100 and Cermark are a couple.
Aluminum reflects over 99% of the power a co2 laser hits it with…
This is done on stainless using LBT100
Good luck
Jack,
Thanks for the reply on this. I’ve heard of Brilliance Laser Ink that is used like a spray paint that washes off with water after etching. I think I’ll give that a shot. I appreciate the feedback.
There is more than one… I’ve use LBt100 and many people use Cermark, so I just suggested those.
Engraving on aluminum requires something like a fiber laser…
Good luck
