Galvanic Corrosion:

The potential differences are expressed in milli-volts. Below the red line, metal considered is attacked.

Corrosion is the result of an electrochemical phenomenon due to the potential difference between different metals, or between a metal and the impurities it contains, when they are in electrical contact. It is necessary to take into account this phenomenon when selecting the supports, fixings and connections. The surface treatment of each component must be compatible:   CABLE TRAY   ACCESSORIES EZ / PG -- EZ / GS GC -- GC / DC 304 L -- 316 L 316 L -- 316 L
