Learn how to create black markings on anodised aluminium using a MOPA laser.
Anodised aluminium can be engraved efficiently and precisely with a laser machine. A white marking is produced when the anodised layer is removed. While this method is perfectly suited for coloured anodised coatings, for natural anodised aluminium, this marking is not clearly visible. Black marking is therefore recommended as it achieves significantly higher quality. Natural anodised aluminium can be finely laser marked in various gray tones, as well as a rich black, with a MOPA laser. This process is ideal for a range of applications, including marking high-quality smartphones.
The secret to black marking anodised aluminium is that you can set extremely short pulse durations with the MOPA laser. The short pulse durations do not damage the surface of the material and the anodised layer is not removed, rather it is just repainted. While the process is entirely different from the production of tempering colours on stainless steel, the result nonetheless is comparable. You can set the filling line distance to adjust in various shades of grey as well as black. Note the smaller the distance, the darker the markings.
You need a 20 watt MOPA laser to black mark anodised aluminium. We recommend using the F-254 lens because it perfectly fits the spot diameter for this application. We recommend setting the following parameters:
Power | Speed | Frequency | Pulse duration |
---|---|---|---|
50% | 1500 mm/s | 200 kHz | 8 ns |
Focus | Filling lines distance | Passes |
---|---|---|
In focus | 0.001 mm bidirectional for a rich black 0.002 - 0.005 mm bidirectional for gray tones | 1 |
We would like to point out that the anodised layers can be very different. For this reason, always use the engraving page for the black marking. Our laser experts would be happy to assist you should you have any further questionss.
To ensure that the parameters we specify work, we suggest you purchase anodised aluminum from our product range.
