Bimetallic shims are profiles made up of a steel layer, another of pure aluminium (EN AW 1050) and a final one of aluminium with high resistance to marine environments (EN AW 5083), welded by explosion in a vacuum atmosphere.
Their main application is to serve as a joining material between steel structures and aluminium structures, typically used in marine construction.
