Introduction The surface topography of extruded aluminum profiles exerts a deterministic influence on their subsequent functional performance, corrosion resilience, and aesthetic quality. Industry benchmarks often mandate an arithmetic mean roughness (Ra) in the submicron regime (0.1\u20130.4\u202f\u00b5m) to ensure compatibility with anodic coatings, precision machining, and tactile"}
