Overview
Fiber is the default choice for marking metal, and for good reason: the 1064 nm beam couples into metal efficiently, so it marks fast, sharp and permanently across almost every common alloy.
Why Fiber Suits Metal
It anneals stainless steel to a clean, corrosion-safe black without breaking the surface. It marks aluminum and brass with high contrast, writes deep, legible IDs on tool steel, and handles iron, copper, gold and silver. Because the mark is a change in the metal itself, it survives heat, oil and washdowns.
Built to Last
Nothing is added on top of the part — no ink, no coating, no label. The mark holds up to solvents, abrasion and years of handling, which is why it’s trusted for traceability that has to outlive the part.
Specs That Matter
For metal work, power and field do the heavy lifting: 20W to 100W, a 100–300 mm field set by the F-theta lens, ±0.002 mm repeatability and marking speeds to 10,000 mm/s. We match the watt count to the alloy and the depth you need.
How to Mark Metal
- Load the part and set the focus distance for the lens.
- Import the mark file and set pulse, speed and frequency for the alloy.
- Run a sample on scrap, check contrast and depth, then save the recipe.
- Fix the jig for repeat positioning and start the batch.
- Scan the codes and log first-article approval.
Where It’s Used

Serial numbers and 2D codes on machined parts, logos on hardware and tools, data-matrix on bearings and fasteners, IDs on automotive and electronic components.
CE Compliance
CE-marked, with conformity documentation available on request. We never claim SASO, SABER, GCC or UKCA we do not hold.
Getting It Right Before You Buy
Send us your metal part. We’ll mark it at the power we’d quote, show you contrast and depth, and confirm the setup before you order.
