You don't want too hard a surface as that reduces the contact area.go for rhodium plating it's the hardest contact metal
Yeah, I guess not. So it doesn't matter whatsoever.A couple of micron on a soft substrate makes no difference to conform ability
That's what I have found. As I frequently have to re-plug connectors, I tend to go for rhodium. My older gold plated plugs are getting rather bare!1cm of mildly increased resistance makes bugger all difference, so go for rhodium plating it's the hardest contact metal. Silver and copper both tarnish, gold gets scraped off.
Why would you need anything more fancy than nickel on a power lead?That's what I have found. As I frequently have to re-plug connectors, I tend to go for rhodium. My older gold plated plugs are getting rather bare!
Did you not read my post?Why would you need anything more fancy than nickel on a power lead?
You said you re-plug things frequently. I have never known nickel-plated power plugs to wear out.Did you not read my post?
So you didn't read my post. A habit you seem to have developed.You said you re-plug things frequently. I have never known nickel-plated power plugs to wear out.
You also said your gold-plated plugs were worn. Nickel is much harder than gold. There is no reason to use rhodium on power connectors, even if you want to believe otherwise.So you didn't read my post. A habit you seem to have developed.
That's my understanding.Exotic metals are for dry contacts, mV to V levels at tiny currents.
Mains voltages at Amps work perfectly with tin or nickel
I can't believe the OP is being taken seriously....
It's a fair enough question, I use Brass connectors on my yacht as it matches the chandlery and doesn't corrode....
Are you forgetting that this is an audio forum? Anywhere else, he'd get a "nice try, very funny."I can't believe the OP is being taken seriously....
That's my understanding.
FYI from an RF project implemented by some former colleagues, with 2 * 50W carriers on an antenna cable and a -120 dBm intermodulation product specification, you must avoid nickel (or any other ferromagnetic material) on or near the RF connectors. The hysteresis causes passive intermodulation. Rusty bolts or similar on antenna assemblies cause loss of capacity and so loss of mobile system operator revenue.
I think there's no such worries for mains, where I believe the UK requirement is for THD to remain lower than 8% (5% for individual harmonics).
And as far as contact resistance is concerned, in the UK's mains system about 10% of consumers see 0.25 Ω or more from just the supplier connection. So no such worries here AFAICS about a reasonable few mΩ from a solidly made IEC connector, whatever the metallurgy.
