Aluminum is widely used in industry projects for its lightweight, its durability, and its high corrosion resistance. Aluminum alloys have been developed for decades to meet industry requirements, and they are nowadays indispensable for all markets including the automotive industry, aircraft and aerospace, building and construction, electronic components, and many more.
This versatile material can be processed in many ways: casting, extrusion, forging, sheet & foil, and offers endless design possibilities.
Beyond its mechanical and chemical properties, aluminum also offers a smooth surface and high contrast potential, making it an ideal material for industrial marking and engraving. Permanent identification on aluminum ensures traceability, compliance, and brand visibility while maintaining the integrity of the part.

Aluminum marking and engraving methods
Laser marking on aluminum
Laser technology is one of the most versatile and efficient methods for marking aluminum. It is a non-contact process, ensuring no tool wear and minimal part deformation.
Depending on the alloy and surface treatment, laser marking produces either a black or white contrast mark. On anodized aluminum, laser technology delivers a high-resolution white marking, while on bare aluminum, the reaction creates dark and sharp engravings.
Laser marking preserves the material’s structural integrity while offering high durability against abrasion and environmental exposure. It is ideal for precise text, serial numbers, barcodes, and complex logos.
Dot peen marking on aluminum
Dot peen creates permanent, readable markings through controlled indentation. The process leaves a dotted mark that can be adjusted for depth and size. On aluminum, the result is clean and consistent, with excellent legibility even on untreated or rough surfaces.
The marking process slightly deforms the surface without removing material, ensuring traceability without weakening the part. It is particularly suited for Datamatrix codes and serial numbers on structural components.
The softness of aluminum also ensures a long stylus lifespan and a low operating cost.
Scribing marking on aluminum
Scribing uses a carbide or diamond tip to draw continuous, deep lines on the surface of the aluminum. This method produces clear, aesthetic, and continuous characters, offering a superior visual appearance compared to dot peen marking. On aluminum, scribing creates deep, sharp lines that remain visible throughout the part’s lifecycle.
As a direct engraving process, scribing is precise, deep, and resistant to wear, making it suitable for identification marks that must remain visible under heavy usage.
Thanks to the softness of aluminum compared to other metals, scribing (and dot peen) offers low operating costs and low stylus degradation over time.
Rotary engraving on aluminum
Rotary engraving, also known as mechanical engraving, is performed with a rotating tool that removes material from the surface. On this metal, rotary engraving produces precise markings with controlled depth. The finish can be polished for a clean aesthetic or left raw for industrial applications. It is suitable for detailed text, logos, or decorative elements.
By precisely removing material, rotary engraving ensures high durability and readability. There is also the possibility to cut through aluminum sheets for the creation of front panels, thanks to the large availability of spindles and cutters.

🔽 What is the best marking technology for engraving aluminum?
The choice depends on your application. Laser engraving is ideal for high precision and detailed graphics, dot peen for permanent industrial identification, scribing for smooth and aesthetic marks on large parts, and rotary engraving for deep, traditional cuts with excellent finish.
🔽 Can aluminum be laser engraved without damaging the material?
Yes. Laser engraving is a non-contact technology that alters the surface of the aluminum without weakening its structure. Aluminum laser engravers create a permanent, legible mark with adjustable contrast, especially effective on anodized aluminum.
🔽 How durable is aluminum marking?
When performed with industrial marking technologies such as laser, dot peen, scribing, or rotary engraving, marks on aluminum are resistant to abrasion, chemicals, and environmental stress. This ensures long-lasting traceability over the entire lifespan of the part.
🔽 Is aluminum suitable for Datamatrix or QR code marking?
Absolutely. Aluminum’s machinability makes it perfectly suited for direct part marking with codes. Dot peen and laser are particularly recommended, providing high readability and compliance with aerospace, automotive, and medical standards.
🔽 What are the visual results of engraving aluminum?
The appearance varies by technology: laser can create white, gray, or black contrast; dot peen produces dotted marks; scribing delivers continuous, aesthetic lines; and rotary engraving cuts deeply into the material, revealing the raw metallic surface.
🔽 How to paint-fill engraved aluminum?
Paint filling is a simple and effective way to enhance the visibility of engraved details on aluminum. After engraving, paint or enamel is applied into the cavities and the excess is removed, leaving only the filled areas. This creates strong contrast, adds color customization, and provides a durable decorative finish. The technique is commonly used for control panels, signage, nameplates, and personalized aluminum objects.
