Application of Laser Engraving Brass

Copper is indispensable in all industries. Laser engraving copper also has its unique advantages for applications. Linxuan provides custom solutions for laser engraving brass/copper. We manufacture industrial brass laser engraving machines with long-term after-sales service.

Copper is indispensable in all industries due to its excellent electrical and thermal conductivity, ease of processing, and durability.

However, laser engraving copper is a huge challenge for users.

As copper metal is a highly reflective material, the light reflectivity is very high, especially mirror copper (the ancient Chinese used copper as a mirror to comb their hair and makeup). When the laser marks copper, the reflectivity is also very high. The laser energy actually used for marking is not much, so the reflected light appears to be very strong during the marking process, while the depth of engraving is very shallow, which also increases the difficulty of laser engraving copper materials.

In order to achieve high-contrast marks, copper parts with high reflectivity must absorb enough radiation. The desired effect can be achieved using a laser with high pulse peak power and variable pulse width.

Nevertheless, if the user wants to mark copper parts with serial numbers, QR codes, and other markings, the advantages of laser marking do not have to be foregone.

Laser Engraving Brass Advantages

Flexible Style

Laser engraving brass is very flexible. It is controlled by computer software, and the pattern and text can be customized. The laser engraving machine can mark the parameter model, LOGO, text, etc. on the brass products, and can also perform general deep engraving.


The logo of laser engraving brass is clear without scratch marks, it is not easy to be blurred and eliminated, it can be maintained for a long time, and the quality is relatively high.

Get Finished Parts Faster

Brass engraving machines save time by completing part preparation tasks such as cleaning and polishing.

Combined With the Assembly Lines

Laser engraving equipment can be combined with the assembly line to realize automatic production and processing, which improves the marking speed to a certain extent, and cooperates with the follow-up process more easily and effectively, so as to reduce the cost and improve the quality. Laser engraving machines are becoming more and more widely used in the processing market of brass/copper materials.

How to Set the Parameters for Laser Engraving Brass?

There are many styles of laser engraving equipment, but only a few equipment (semiconductor laser engraving machine, fiber laser engraving machine, ultraviolet laser engraving machine) can mark metal copper/brass.

The price of UV laser engraving machine is relatively high, which is suitable for high-end product plastic marking, and it is relatively uneconomical to use for brass. Here is just a suggestion on how to set the parameters of the fiber laser engraving machine and semiconductor laser engraving machine for copper material.

When marking with a fiber laser engraving machine, pay attention when setting parameters:

  1. Slow down the marking speed and use high frequency.
  2. The power of marking should be moderate, not too large. Excessive power will lead to poor light pattern and lead higher reflectivity.
  3. Use a small format field lens for processing.
  4. Try to make the laser spot mode the best, and use a fiber laser engraving machine with adjustable pulse width for better marking effect, moderate pulse width, the spot is softer and better.

When using a semiconductor laser engraving machine to mark metal copper, there is not much change in the adjustment of laser parameters. It is just that the temperature of the chiller is adjusted before marking to make the laser output more stable. Other parameters can be borrowed from the fiber laser engraving machine, set in slow speed, high frequency, power 50%-60%, moderate pulse width, etc., and you will get a satisfactory laser marking effect.
