Gallium Settings

When laser cleaning gallium, you'll want to approach it unlike harder metals such as steel or titanium, which handle intense heat without issue. Gallium's unusually low melting point sets it apart, risking surface liquefaction if energy builds up too quickly. Start with reduced power and faster scan speeds to strip away oxides or residues while keeping the material solid. Make sure you avoid prolonged exposure in one spot, as this can cause uneven melting and distort the underlying structure. This method exposes a clean, intact surface ready for semiconductor or medical applications.
