Here is the ACMER A2 1064nm infrared laser module engraving engraving test. This video highlights the laser module's ability to engrave aluminum, stainless steel, color-anodized aluminum and brass. The infrared laser beam interacts with the surface of these materials, leaving precise and crisp engravings.
Of course, it can also perform fine engraving on a wider range of materials, such as gold, silver, platinum, titanium, plastic silicone, acrylic, stone, iron, etc.
