Contact of dissimilar metals (except for the combination of aluminum and steel) should be avoided wherever possible to lessen the potential for ____.
A) galvanic action
B) inadvertent shorting
C) structural weakening
D) static charging

Question

Quizplus · Accepted Answer

Contact of dissimilar metals can lead to galvanic action, which is a chemical reaction that can result in corrosion and deterioration of the metals. It is important to use similar metals or a protective barrier between dissimilar metals to prevent galvanic corrosion. Inadvertent shorting, structural weakening, and static charging are not necessarily caused by contact of dissimilar metals.
