Laser engraving metals

The BRM Co2 and Fiber lasers are perfectly suitable for processing many kinds of metal. Logically there are many ways and possibilities for laser engraving this specific material.

Co2 lasers

The Co2 lasers of BRM are machines that are capable to engrave metal. To make this happen it is necessary to apply Cermark or Thermark on the material. The spray needs to be applied because most of the metals are reflective which could damage the lens or laser tube when processed without Cermark or Thermark. The laser beam could bounce off the material into the machine and this harmful to the machine and dangerous as well.

Cermark is a quick and easy way to add laser markings to many metals. Stainless steel, copper, nickel. All of these metals can be engraved with a BRM Laser using the Cermark or Thermark spray. The result is beautiful!

Fiber Lasers

Thanks to the ten times smaller wavelength than a CO2 laser beam, a fiber laser beam easily engraves hard materials such as (precious) metal. If you want to engrave something on metal with a CO2 laser machine, you must first pre-treat the material with a spray. This is not necessary for a fiber laser machine. The high beam quality and small focus spot of a fiber laser beam guarantee a fine and precise cut, which allows you to work both quickly and carefully. And that without distorting the surface. A fiber laser skips the melting phase.

Efficiency and Security of the Fiber

Efficiency plays an important role in commercial applications of markings. A fiber laser beam requires relatively little power to achieve a high beam quality. This is related to the optical qualities of glass fiber; the fiber not only creates a laser beam by adding electricity, but it also conducts this beam. In a fiber laser machine, therefore, fewer separate parts (such as mirrors) than in a CO2 laser machine are required to create a targeted and reliable laser beam. This makes a fiber laser machine less vulnerable to dust particles and less maintenance-sensitive than a CO2 laser machine. But also safer: a fiber laser works vapor-free.

The efficiency of a fiber laser machine is also at its speed. This machine converts a relatively large amount of power into speed. To be able to work just as fast with a CO2 laser machine, much more power is needed. A fiber laser machine is already supplied with an output of 20 watts. The minimum power required by a CO2 laser machine soon reaches 80 Watt.
