Many fields, including space technology, shipbuilding, the marine industry, and the automotive sector, heavily rely on aluminum and its alloys. Each metal and alloy is significantly influenced by its wettability. In this study, Four distinct patterned surfaces were produced on Al–Mg alloy (AA5754) using a nanosecond pulse fiber laser. Olympus 3D microscope was used to evaluate the alteration in surface morphology. Wettability was measured with the help of Ossila contact angle goniometer set up. Almost all structured surfaces attained the hydrophobic state except 10 no. of lines per 1 mm at 1000 mm/s scanning speed. 117.36° ± 6.8 was the highest contact angle for 10 no. of lines at 500 mm/s. At a scanning rate of 500 mm/s, surface wettability rises initially and then decreases as line density increases; at a scanning speed of 1000 mm/s, wettability of surfaces exhibits opposite patterns. The contact angle increased by 102.20% at 500 mm/s and 62.80% at 1000 mm/s when compared to an untextured surface. Consequently, it may be said that scanning speed has a greater impact on wettability than line density.
