Laser Etching Black Anodized Aluminum

This week we ll show you that it is possible to mark black on anodized aluminum.

Laser etching black anodized aluminum.

Laser marking anodized aluminum is a selective process known as laser etching. While this method is perfectly suited for coloured anodised coatings for natural anodised. Durablack is resistant to sunlight uv radiation abrasion high temperatures and chemical exposure. Anodised aluminium can be engraved efficiently and precisely with a laser machine.

In side by side tests durablack outperforms black anodized aluminum and laser markable acrylic tape in select applications. A white marking is produced when the anodised layer is removed. Laser etching anodized aluminum. The color of the mark is highly contrasted between the anodized aluminum and the laser induced mark.

In this case the ls 1630 produced excellent r. Produce high quality dark markings on anodised aluminium. This type of laser is capable of scribing right through the anodic coating to the bare substrate underneath. Traditionally fiber and co2 lasers have only marked white on anodized alumin.

Durablack is co2 laser markable aluminum for durable on demand marking for harsh operating environments. One piece of equipment they have i. I live near a diy workshop called techshop they have 1m worth of equipment that i can get access to for about 100 a month. Laser machines are an ideal technology for marking and engraving on anodized aluminum and can be used with both co2 and fiber systems.

Yag for yttrium aluminum garnet is a crystalline solid state laser that emits a wavelength of 1 064 micrometers 1064 nanometers. Depending on the color of the anodized aluminum itself a fiber marking laser can efficiently produce darker marks while a co2 marking system can produce bright engraving with contrast. The laser beam only removes the anodized layer from the aluminum piece resulting in high quality marks. This instructable will show you how to use a laser cutter to etch anodized aluminum.

There are two types of lasers used for etching or scribing laser engraving metal surfaces.
