Resist corrosive elements

Increase conductivity/lower contact resistance Provide high, continuous service temperatures (maximum) X (500ºF/260ºC) *Note: Never connect an aluminum surface to a silver plated surface. Aluminum in contact with silver results in a highly corrosive joint, which will further result in a high resistance connection. — — X X (347ºF/175ºC) — X (650ºF/343ºC)
