Anodising has become a dominant form of finishing for aluminium. This is largely due to its cost effectiveness, availability and suitability, across a whole host of applications and industrial sectors. Laser marking anodised aluminium, has also become an accepted process across these industrial sectors.
Anodising is an electrolytic passivation process. It changes the microscopic texture of the aluminium by modifying the crystal structure near the surface. The passivation thickness will be between 10 and 25 microns, generally between 10 and…

A good example of product branding by laser marking is anodised aluminium. It is used in high end audio accessories in the form of cable tidies. The aluminium is highly polished, prior to anodising, in order to achieve the high gloss finish on the part.
The laser process, delivers small pulses of energy to the component surface. These pulses have enough energy to vaporise the surface of the aluminium where the anodised coating occurs. This exposes the base material, aluminium,…
In this example, laser marking barcodes are used as part of the overall vehicle information plate, with the barcode containing the vehicles serial number information.
Anodised aluminium is a widely used material combination in today's industrial markets. The ability to create a wide range of colours makes it ideal for many applications.
The laser process is used to remove the anodised surface, creating a very high contrast level. This contrast level is important in the reading of…
This example shows laser engraving anodised Aluminium scaling. The laser delivers small pulses of energy which heat the material surface until it vapourises. This removes the layer that contains the black anodising exposing the base material below. Providing the required contrast between the two finishes.
To create linear guides by laser engraving anodised aluminium.
The guides are for the side of a machine providing a quick positional reference. In this example, the full scale is much larger…
Product branding anodised aluminium is a widely used application across many industrial sectors. The anodised process is removed to expose the aluminium base material using laser engraving.
The finished image is created, when the laser removes material from the surface in a raster scan motion. This is followed by the laser beam being used to trace around the image outline, providing a sharper edge.
The quality of the finish on the aluminium is greatly dependent on the material…
The example shows laser marking black anodised aluminium. Removing the anodising creates high character contrast ideal for this application.
Anodising is an electrolytic passivation, widely used across industry on aluminium for a variety of reasons. The process offers a range of colour variations through the use of colour dying. The process changes the microscopic texture of the aluminium by modifying the crystal structure near the surface.
Laser marking black anodised aluminium, provides the highest contrast to the characters.…
This anodised aluminium laser marking/engraving sample kit, was produced by the manufacturer of aluminium extrusion section, to demonstrate the colour range within this particular group set.
Anodising is an electrolytic passivation, that is widely used across industry on aluminium for a variety of reasons. The process can also provide a huge range of colour variations through the use of colour dying. The process changes the microscopic texture of the aluminium by modifying the crystal structure near the surface. Laser marking…
Laser marking curved surfaces is common place on industrial products today. As long as the basic rules are followed it is a fairly easy process to complete.
In this example, the material is aluminium which absorbs the laser energy very well, making laser marking on curved surfaces much easier.
The laser has a focal position, which is where both the spot size and energy levels are optimised. But in this instance, we have to set the focal position half way…
This cylindrical product is manufactured from aluminium, is clearly anodised in order to have the surface more tolerant to handling and daily usage. Laser processing was selected, due to its flexibility and process speed proving attractive per unit costs. Laser marking corporate logo taking place directly onto the aluminum.
Here, we are using a 20 watt fibre laser in a low waveform configuration, in order to break…
Laser engraving aluminium is common place in industry today. In this example, we are laser engraving aluminium defining the product details along with some technical information. The main stipulation from the customer, is the part will be clearly anodised following the marking, so we are instructed to ensure the depth and clarity of marking will withstand the anodising process.
This electrolytic passivation is widely used across industry on aluminium for a variety of reasons. The process can also provide…
In this example, the aluminium laser engraving is performed on aluminium plate. The application is custom label tags for boxes containing snooker cues. The aluminium laser engraving produces either personal details, or in this case, organisations who ultimately sell the products to their fans. In this case, a West Bromwich fan.
With laser marking complex logo's, it is important to understand the difference between Vector files and Bitmap files. Vector files are mathematical formulas…
