separating lead from copper

Architecture Design Handbook: Fundamentals Copper

In areas with severe exposure, lead or similar gasketing materials should be used, except between copper and aluminum. Regardless of the method used to separate the metals, wash from copper surfaces should be prevented from draining onto exposed aluminum. Traces of copper salts in the wash may accelerate corrosion of the aluminum.
