The Intro Guide to Dissimilar Metals

Carbon steel Aluminum Zinc Since stainless steel and aluminum have a large gap in nobility, theyre dissimilar. That means pairing them up will have a higher chance of leading to galvanic corrosion. On the other hand, metals like copper and stainless steel are similar. Thats why steel pipes and copper tubing work well together.

What is galvanic corrosion/bimetallic corrosion/dissimilar ...

Stainless steel has an effective passive film so the available corrosion current able to be carried by charged atoms ions is quite low. If the behaviour of a copper/steel and a stainless steel/steel couple is compared, the copper/steel coupling is a more significant galvanic problem despite the similar potential separation of 0.35 volts.

Galvanic Corrosion Bimetallic Corrosion Dissimilar Metal ...

Galvanic corrosion also commonly termed bimetallic corrosion is an electrochemical process. That is to say, it occurs as a result of the flow of very small electric currents usually between two dissimilar metals which causes the more anodic of the two metals to corrode, the noble or hodic metal being unaffected.
