    Galvanic Corrosion Solutions

    I am designing Liquid Petroleum dividers and I am very worried about galvanic corrosion. The blocks will be made from Aluminum but the hose fittings will be brass. My first reaction was to anodize the aluminum but I already know I will be asked if we can avoid this to save a few bucks. I have...
