What type of resistance should all exposed materials used in galvanic isolators and mounting hardware have?

Galvanic isolators serve an important purpose in marine and electrical applications by preventing galvanic corrosion, which can occur when dissimilar metals come into contact in the presence of an electrolyte, such as saltwater. To fulfill this function effectively, any exposed materials utilized in these isolators and their mounting hardware require corrosion resistance.

Corrosion-resistant materials are crucial because they can withstand the harsh marine environment where exposure to water, salt, and other corrosive elements is inevitable. This resistance ensures the longevity and reliability of the galvanic isolator, maintaining its ability to protect the vessel's metal parts from corrosion over time.

While other properties like fire resistance, shock resistance, and heat resistance are important in various contexts, they are not the primary concern for materials in galvanic isolators. The main goal is to ensure that the materials do not deteriorate due to environmental factors, which can compromise the isolator's effectiveness.
