Metal Processing

Steel, Aluminum, Silver and many more metals

Laser marking has proven successful for etching metals, owing to its durability and the fact that it does not damage the material. Most bare metals can be laser marked with the use of marking compounds. Anodized aluminum can be directly marked with a laser and the high contrast image produced is ideal for serial tags, identification plates and two-dimensional barcodes. Laser marking on metal delivers highly durable marks without sacrificing material integrity.

Metals suited for laser marking include

  • Aluminum
  • Anodized aluminum
  • Brass
  • Carbide metal
  • Chrome coated metals
  • Cobalt
  • Copper
  • Eloxal
  • Gold
  • Iron
  • Nickel
  • Pewter
  • Platinum
  • Silver
  • Steel
  • Tin
  • Titanium
  • Tungsten
  • Zinc

What are the benefits of laser marking metals?

Laser marking metals with the laser is an extremely accurate and clean way of working on metal. Markings like serial numbers, codes and logos can be applied on products and components in maximum resolution, and most metals can be laser marked by first applying a marking compound to the metal surface. The laser beam fuses the marking compound with the metal, leaving behind a dark mark (almost black) that does not rub off and is not affected by cleaners and solvents.

What is laser marking metal used for?

Laser mark tools and other high value assets with custom logos, artwork, ID and serial numbers, barcodes, UID codes and 2D matrix codes. Laser systems are great tools for etching anodized aluminum instruments and control panels, as well as consumer electronics like iPods and cell phones.

Is laser cutting metal possible?

Whilst most laser engraver/cutting machines will not cut metals we do have a separate range of machines that will cut many metals potentially up to 150mm thickness and with the smallest machine footprint of 1.5m by 3.0m.

For more information have a look at our MicroStep machines.
