Bronze is more compatible with galvanized steel and aluminum.
Brasses and Bronzes -0.40...aluminum is -0.75 or higher. "It will always be the metal with the most negative anodic index which will ultimately suffer from corrosion when galvanic incompatibility is in play..."
High Brasses and Bronzes -0.45
What's zinc coated steel got to do with it? And what support do you have for your claim that bronze is any better than brass? Show your math.
