General Metal Engraving / Base Settings

In the world of metals the grade, type, hardness and chemical composition are
endless. Metal alloys are engineered for specific applications and have their own
strengths and weaknesses. With such an unlimited selection, we've yet to come across
a metal which proved to be incompatible with the FiberMark.
Metals can be engraved at just about any settings. Of course, there are many variables
to consider for metal engraving. The lasers wattage, hardness of metal, desired mark
(etch, polish, anneal) and the required time/contrast/depth will have to be considered
when deciding on the final settings.
Below are general guidelines for most common metals. Settings will have to be
adjusted based on wattage. A general rule of thumb is to use less speed, and lower
frequency settings for 10 and 20 watt fiber lasers, and less power, higher frequency
for higher wattage Fibers (30 and 50 watt).
Etching of "Metals"
 8 - 30% Speed
 100% Power
 1 - 10% Frequency
 -.020" to +.020"Focus
 400 – 600 DPI
Like our C02 counterparts, the slower the speed setting, the deeper the etching.
However, many metal applications can be processed at higher speed settings in the
range of 50-100%. Again, consider the marking requirements. If the only stipulation
is permanency, you'll find the FiberMark can engrave a broad range of metals at
higher speeds, regardless of laser wattage. Don't be afraid to turn up the juice!
