Lasers are a great way to create engravings and markings on anodized aluminum. Depending on the color of the layer, a CO2 laser produces great contrast and a bright engraving. The fiber laser is a highly effective way to mark anodized aluminum. The MOPA laser can be used to mark in many different shades such as gray up to a rich black, without stripping away the surface. The result is comparable to the annealing marking on steel. The MOPA laser, often used on natural anodized aluminum, creates a clearly legible, high-quality marking, that can be applied to smartphones and other items.
Suitable materials for laser engraving and laser marking include:
- Anodized aluminum
- Natural anodized aluminum
- Anodized layers in all colours
Depending on the requirements and application, anodized aluminum can be engraved or marked.

What is the point of buying a laser for the laser engraving and laser marking of anodized aluminum?
Fast, flexible and variable marking of anodized aluminum
With the laser, you can have countless options for marking anodized aluminum. Depending on the batch size or number of units, you can find the ideal flatbed system or Galvo laser to meet your requirements. The laser is also very flexible for marking all types of content such as serial numbers, data matrix codes and a variety of other content. Not only can you engrave anodized aluminum (which removes the anodized layer), you can also produce black markings on the anodized layer. Natural anodized aluminum in particular can be marked in different shades of gray to a rich black.
Function and advantages of laser technology
Black marking of anodized aluminum
- High-quality, qualitative markings that increase the value of your products.
- No removal of the anodized layer and therefore no damage to the surface.
Advantages of a Trotec laser
- SpeedMarker marking lasers with MOPA lasers facilitate this special marking of anodized aluminum.
Cost-efficient production
- Direct marking means no costs for supplies such as inks, chemicals, pastes or sprays
- The need to handle and dispose of these materials (which is often very expensive) is also eliminated
- No pre- and post-treatment is required
Other advantages include:
- Integration options - The SpeedMarker with a maintenance-free fiber laser can be used as a laser work station or it can be integrated into a production line
- Long product life with low ownership costs - The robust mechanics of the Trotec laser systems is designed for years of intensive use with minimal servicing
Flexible, dynamic data can be marked
- Different markings with dynamic content possible without refitting or changing tools
Other advantages of a Trotec laser
- Intelligent and intuitive SpeedMark marking software can easily process data from existing ERP systems and all dynamic contents in codes
Permanent marking
- In contrast to other technologies, lasers create permanent markings that are heat, acid and abrasion-resistant
- Lasers are an efficient and effective way to meet traceability and quality assurance requirements
Other advantages of a Trotec laser
- Product portfolio with matching fiber laser systems for all requirements
- Flatbed systems with a working surface up to 40 x 24''
- Galvo work stations with working surfaces up to 51.2 x 17.7''
- OEM Galvo fiber laser for integration into production lines
- Customization options to meet unique requirements
Create precise markings
- Precise and very small geometries can be marked with high accuracy
- Marking processes can be combined
Other advantages of a Trotec laser
- High-quality optics and best beam quality thanks to high-quality components
- Camera-based component positioning for maximum precision and ease of use
Diverse design possibilities
- Practically any design can be realized with the laser
- Even 1-point fonts and smallest geometries are still clearly legible
- Full freedom when designing markings, logos, designs, bar codes or serial numbers
- Even photos can be applied quickly and easily
Other advantages of a Trotec laser
- DirectMark or JobControl Software allows you to laser mark directly from the graphics program. It's as simple as printing
Boost production efficiency
- High-speed marking, even of variable contents (e.g. serial numbers, codes)
- Different markings possible without refitting or tool change
Advantages of a Trotec laser
- Intelligent and intuitive marking software for easy operation
- Fast and precise positioning of components using a camera system: SpeedMark Vision – Smart Adjust
- Integrate contents from ERP data files
Product recommendations
Laser marking aluminum in black
Anodized aluminum can be easily laser marked with MOPA lasers. It can produce a variety of gray tones all the way to a rich black. The special thing about it is that the short pulse durations don't damage the surface of the material, or just barely. The anodized layer is not removed, but repainted. Although the process is completely different from the production of annealing colors on stainless steel, the results are comparable.
Especially with natural anodized aluminum, you can create very nice markings. But anodized aluminum in other dark colors can be lasered as black. In combination with conventional engraving (or removal) of the anodized layer, there are many possibilities for marking products made of this material.
