Laser marking aluminum parts for readability

Key factors affecting marking contrast on anodized and bare aluminum.

Choosing the right solution for laser marking aluminum parts for readability requires evaluating materials, production goals and operating conditions together. This guide outlines the main questions to consider before requesting a quotation.

Bare versus anodized aluminum

Bare aluminum and anodized surfaces behave differently. Coating color, thickness and surface texture can alter mark visibility.

Planning code readability

For serial numbers and two-dimensional codes, character size, cell dimensions and scanning angle matter. Reflections from shiny surfaces can affect reader performance.

Building a process from samples

Testing samples from the same production batch helps balance contrast and speed. Share part photographs and material details during the quotation process.
