Yes, galvanic corrosion can occur when aluminum bronze is in contact with steel because these two metals have different electrode potentials, which means they will react when they come into contact with each other in the presence of an electrolyte (such as saltwater). This reaction can cause the aluminum in the bronze to corrode, which can lead to structural damage if left unchecked. To prevent galvanic corrosion in these situations, it is important to use appropriate insulation or coatings to separate the two metals.
