Iridium Settings

I've found that laser cleaning Iridium stands apart from other precious metals like platinum, which yield more easily to standard pulses. Its extreme density and hardness demand a more controlled approach, so this works best when you begin with reduced power to prevent surface scattering. Unlike those softer counterparts, Iridium's low thermal expansion keeps it stable under heat, allowing multiple passes without warping, but watch for its high reflectivity in the middle of the process—it can bounce energy away and leave residues if you ramp up too quickly. Adjust by tightening the focus and slowing the scan to expose contaminants fully while restoring the underlying shine. This reduces the risk of incomplete removal and preserves the material's corrosion resistance for applications in aerospace or jewelry.
