That'd be enough to give an inspector justification for nixing the above connector. Industrial mercury use is under very close scrutiny, and whether it's a commercial part or not doesn't necessarily matter anymore. My employer, for instance, wouldn't allow it unless I made a very thorough case for having no other practical option, documented a hazmat containment/cleanup plan, and an end of life disposal plan.

That's not to say the connector is illegal by default, just that it's in a gray area. I think any team wanting to use it these days would be facing a pretty hard sell with the inspectors.

Re: What Kind Of Metal Can We Use For FRC?

Under current rules and inspector interpretations, this rotary connector must be designed to work on moving bodies as well as providing rotary connections. Often these devices are not designed nor intended for anything but stationary rotary mechanisms. Vibration, misalignment and shock can cause these to leak and that would bring an event to a halt.
