It's called Galvanic Corrosion. Ally and stainless need separating to stop that process, grease works quite well, if they can't be separated then an sacrificial anode is used. I imagine that it gets wet up there and stays wet for long periods. Stainless can also "cold weld" if anti scuffing paste isn't used but not normally on anything that small.

Your plastic replacements are the way forward
