All dissimilar materials have the potential to react with each other when they are brought together in the presence of a catalyst. In most circumstances this reaction is so mild as to be of no importance, but when the wrong materials are used in combination and then exposed to an electrolyte such as water the effects can become much more noticeable. For applications where humidity is low then you can generally ignore galvanic corrosion. If on the other hand you are working on a project for use in damp conditions or outside then it is best to pay some regard to the possible effects of galvanic corrosion.
As a rule it is best to use metals which are as close together as possible in the table below. Doing this will help to eliminate any possibility of galvanic corrosion. If you do have to mix materials then take a look at the galvanic compatibility section.
Often when design requires that dissimilar metals come in contact, the galvanic compatibility is managed by finishes and plating. The finishing and plating selected facilitate the dissimilar materials being in contact and protect the base materials from corrosion.
For harsh environments, such as outdoors, high humidity, and salt environments fall into this category. Typically there should be not more than 0.15 V difference in the "Anodic Index". For example; silver - nickel would have a difference of 0.15V being acceptable.
For normal environments, such as storage in warehouses or non-temperature and humidity controlled environments. Typically there should not be more than 0.25 V difference in the "Anodic Index".
For controlled environments, such that are temperature and humidity controlled, 0.50 V can be tolerated. Caution should be maintained when deciding for this application as humidity and temperature do vary from regions.
