Laser Cutting Aluminum: Problems, Fixes & Thickness Limits
Aluminum is simultaneously one of the most laser-cut metals in industry and the one that generates the most troubleshooting threads. It reflects the beam that is supposed to melt it, pulls heat away from the cut faster than almost any other engineering metal, and produces a clingy bottom-edge dross that steel cutters never have to think about. This guide explains why aluminum fights the laser, walks through the four problems that account for nearly every bad aluminum cut, and gives the thickness-by-wattage numbers that separate marketing claims from what a machine cuts cleanly in production.
