Copper (401 W/m·K) and aluminum (205-235 W/m·K) dissipate heat faster than ferrous metals. This requires higher fluence (5-8 J/cm²) or shorter pulse durations to achieve ablation before heat spreads. Laser cleaning remains effective where continuous methods fail.
Reflectivity & Backscatter Control
Polished aluminum and copper reflect up to 90-95% of 1064nm laser energy, creating backscatter hazards. UV wavelengths (355nm) improve absorption to 40-60%. Enclosed beam paths and OD 7+ eyewear are mandatory for safe operation.
Oxide Layer Characteristics
Aluminum oxide (Al2O3) has a higher ablation threshold (3-5 J/cm²) than the base metal, allowing selective oxide removal without surface melting. Copper oxide (CuO) absorbs better than pure copper, enabling self-limiting cleaning.
Aerospace Titanium & Exotic Alloys
Titanium alloys require low-fluence (1-3 J/cm²) cleaning to avoid alpha case formation or hydrogen absorption. Laser cleaning meets ASTM B600 and AMS 2700 standards for surface preparation prior to bonding or coating.
