I also agree a high pressure contact withstands corrosion tremenduosly. I have taken apart crimped copper connectors, together for fifty years, and they were bright. The two contacting metals must be of the same atomic structure. If they are not the same, they will start to corrode upon contact. (Here he goes again!)
~~~~Basically metals of dissimilar atomic structures, no matter how minute, have differences of electrical potential by construction. If you ever had an electrical device spark/arc/shortcircuit, there was always a pitting or deposition of metal from one surface to another. Along with the pitting is some oxidization. Warning! Warning! Stagnant portion of brain now being accessed!
~~~~This has been brought to you by the makers of "Space Food Sticks" the snacks of the astronauts.(Anybody remember those things?) My typing finger is tired, my brain is smoking, time to butt out. <(+)><(+)> Thanks AG for puttin up with me!............................ ............... () .....................................
