Introduction

Laser marking is a precise and efficient method used for engraving various materials. Metal marking, in particular, requires special consideration due to the material's reflective nature. This article examines whether CO2 lasers can effectively mark aluminum, analyzing specific conditions and parameters.

Understanding CO2 Lasers

CO2 lasers operate at a wavelength of 10.6 micrometers and are widely used for cutting, engraving, and marking a variety of materials, including non-metals and metals with coatings. Their efficacy in marking uncoated metals like aluminum is less known and subject to certain requirements.

The Aluminum Marking Process

Aluminum requires a precise approach due to its high thermal conductivity and reflectivity. CO2 lasers can mark aluminum effectively through anodization or by using marking agents that enhance absorption. The process involves surface preparation, choosing an optimal laser setting, and post-processing to ensure durability.

Optimal Parameters for CO2 Laser Marking

The efficiency of CO2 lasers on aluminum depends significantly on the parameters set during the marking process:

• Power Settings: A typical power range between 25W and 100W is recommended for marking coated aluminum. Higher power settings should be used for deeper engravings.
• Speed: A marking speed of 300-500 mm/s balances efficiency and quality, ensuring clean and visible marks.
• Frequency: A frequency range of 20-100 kHz is optimal for achieving fine detail without causing excessive heating.
• Focus: Precise focus should be maintained to achieve clear marking, often controlled by adjustable lenses or autofocus technology.
