I was looking at Timberbits, and saw that there's a choice on platings between:
trivalent chrome and chrome.

Best I could come up with.
4) What is the difference between trivalent chromates and hexavalent chromates?
Hexavalent chromates were once the most commonly used chromate throughout various industries. Today metal finishing processes are moving towards trivalent chromates to meet European Union initiatives End of Life of Vehicle (ELV) and RoHS. The usage of hexavalent chromates has been limited, resulting in trivalent chromates now being used more predominantly. Trivalent chromates produce a harder, scratch-resistant coating with lower water content providing more heat resistance. EPI's trivalent chromates address some of the major issues when switching over from hexavalent chromates:
Clear as muddy water.

I have purchased some of the trivalent chrome barons from Timberbits and from a physical appearance, I would describe them as "smokey chrome". I actually like the look of them a lot.
Well, now that you have straightened that out.:wink:
I saw those too and was wondering the same thing.

Hexavalent chromium is a carcinogen. It's probably best to avoid it (if you know that's what it is), especially if you consider machining. Trivalent chromium is fine.

Bottom line is trivalent chrome is a much harder plating that traditional chrome plating. It is also more environmentally friendly.
It is also a "little darker" than traditional. Not quite black ti, but darker.
