Laser marking on aluminum with a 20-watt fiber laser is an efficient and precise method for creating permanent markings. This process allows for the engraving of detailed text, logos, and barcodes with excellent clarity and contrast. The non-contact nature of the fiber laser ensures that the aluminum remains undamaged, while the marks are resistant to wear, corrosion, and high temperatures. Ideal for industrial applications, this technique provides a durable and reliable solution for product identification and traceability on aluminum surfaces.
