Laser marking is commonly used for component traceability and identification. It allows parts to be tracked throughout the manufacturing process and can even help identify the supplier that produced them. Common identification formats include data matrix codes, QR codes, and alphanumeric serial numbers. We frequently apply laser marking to aluminum, steel, and stainless steel turned parts.

Because aluminum surfaces have high thermal conductivity, fiber lasers can mark them at elevated temperatures and create deep marks on bare aluminum. This helps ensure the markings remain readable after anodizing. AL 6061 is the most commonly laser-marked alloy, although all aluminum types can be marked. Typical aluminum parts we process include flanges, knobs, and more.

Steel is a hard material and usually requires longer marking times than many other metals. However, marking speed can be improved by creating white marks instead of black marks. White marks provide strong contrast against the natural color of most steel surfaces. We can laser mark any steel alloy, including anodized steel, carbon steel, and tool steel. Typical steel parts we process include plates, bodies, caps, and more.

Laser marking is most commonly applied to stainless steel grades SUS 303, 304, and 316, but it can be used on any stainless steel grade. Typical stainless steel parts we process include port housings and other automotive components.
