Wiring connection question: solder vs conductive grease vs nothing? 140-160

Soldered electrical joints just don't carry power as well as pressure connections. If soldering was better it would be widely used in industry and military where reliability is of utmost importance. I've done electrical installations in semiconductor Fab plants, paper mills, steel foundries, mining machines, on department of defense contracts, and more. No one uses soldered connections.

Sorry but I can't tell you how to check for tin or aluminum plating. I doubt aluminum would be used, because raw aluminum rapidly oxidizes in the air to clear aluminum oxide. Aluminum oxide is a poor conductor. When terminating aluminum conductors you always make the aluminum fresh by scraping, brushing, or sanding and immediately terminating it before the aluminum oxide can form again.
