Black Metal Laser Spray by Brilliance Laser Inks is an aerosol spray designed for marking metals in combination with CO2 and fiber lasers. Nowadays diode lasers become very strong, so I wanted to find out what can we do with 5W or 10W diode lasers too. Tested materials: stainless steel, regular steel, aluminum, brass and copper.

Final settings used in this video:
With every setting: S1000 (max power), M3 (constant power). 14 Lines/mm (started with 12), Speed variate.

5W (TTS-55)
Stainless steel: 1600 mm/min
Alu, Brass, Copper - marking not permanent

10W (Atomstack P9)
Stainless steel: 1600 mm/min
Regular steel: 800 mm/min
Alu: 100 mm/min (marking strong, but black color visible on scratching object)
Brass: 400 mm/min (marking looks very durable on 2 days test, but scratchable with sharp object)
Copper: 200 mm/min marking strong but it's coming down if scratched.
