Yes, modern fiber lasers handle 17–25mm aluminum aluminum effectively with proper parameter optimization. Use nitrogen assist gas at 12–18 bar pressure for clean edges and proper beam parameter optimization. Auto-focus cutting heads with anti-reflection protection are essential for consistent results. Key parameters include: faster piercing speed to prevent back-reflection damage, optimized focal position (typically 0 to -2mm below surface), and pulse-mode piercing for thick sections. Our 19 listed machines are verified capable of processing this aluminum thickness range.
Aluminum presents three main challenges for laser cutting: (1) High reflectivity at 1070nm wavelength (fiber laser) — approximately 92% of laser energy is reflected by unprocessed aluminum surfaces, requiring protective anti-back-reflection systems on the cutting head and laser source. (2) High thermal conductivity (237 W/m·K vs. 50 W/m·K for steel) — heat dissipates rapidly from the cutting zone, requiring more power to maintain the melt pool. (3) Low viscosity molten aluminum — the melt pool is more difficult to eject cleanly, potentially causing dross adhesion on the bottom edge. Modern fiber lasers with BPP values under 4 mm·mrad mitigate these issues through higher focused energy density.
