Molybdenum Settings

When laser cleaning Molybdenum, unlike softer non-ferrous metals like copper, its exceptional heat resistance lets you push higher powers without quick melting. This works well for tough contaminants in aerospace parts. I've seen it clear buildup fast on tooling dies. But its dense structure spreads heat evenly, so overlaps must stay tight to avoid uneven spots. Tends to shine up nicely. Watch power spikes at the end—they can crack surfaces if unchecked.
