Re: Stainless steel N connector.
Bicon X1 finds it's main use for joining copper
and aluminium also aluminium and aluminium in power distribution.
Although tested with a meter it may seem non conductive it has
zinc particles. I have taken to using it for assembling antennas.

Stainless Steel is a particularly bad
conductor of electricity, 40 times worse than copper, 10 times
worse than Nickel and only 1.7 times better than nichrom, as
used in resistance wire! So I doubt you will find Stainless
steel N type plugs.
I use nickel plated N Types on boats with good results but not
mounted on aluminium.
Some jointing compounds e.g. Duralac create an open circuit
across the joint however Bicon should be fine.

I have just ordered a tube of Bicon X1.
