Metals suitable for laser marking

Laser marking machines for metal can process a wide variety of industrial metals, enabling permanent, precise, and high-contrast markings without physical contact or the use of consumables.

By adjusting laser parameters such as power, frequency, pulse duration, and scanning speed, it is possible to achieve different marking effects — including engraving, annealing, and surface marking — while preserving the mechanical integrity of the material.

Laser marking is particularly valued in industrial environments where traceability, durability, and readability over time are critical, even under exposure to abrasion, chemicals, or high temperatures.

Each metal requires a specific laser configuration to guarantee optimal marking quality, contrast, and cycle time.

Automator laser marking machines for metal are designed to adapt to different materials and production requirements, offering reliable performance across a broad range of industrial metals.
