Laser Engraving Anodized Aluminium – The right way

Posted By Adrian

Anodized Aluminium is a very versatile material, it has high contrast when laser engraved, moderate wear resistance and is highly resistant to corrosion. This makes it a very good candidate for making signs, plaques or machine tags. Because of its high contrast once engraved, it is also perfect for barcoding and QR applications.

From experience, I’ve found that many people are unable to get the very best contrast out of this great material. Today I made a small 90x60mm interior grade plaque for my blog.

I started out using the ever trusty CorelDraw X7 software package, to create the vector graphic I wanted to engrave. I use a vector format because it can be scaled without the fear of resolution issues. For more information on vector graphics

  1. Hey thanks! I have used your settings with great success. The anodized alluminium plates we have look great with those settings. Thank you

  2. Hy, you think 15w diode can make white marking over black standard and black hard anodized 7075 and 6061 ?

    1. It will, but engraving will be slow. Also depending on the wavelength of the diode you may not get a perfect black to white colour change… might be a bit grey.
