What is the difference between bronze and brass?
Bronze and Brass are both principally an alloy of Copper and Zinc, Bronze however has the additional element of Tin that inhibits the oxidation process and confines it to the surface of the metal only. As a result, bronze forms a natural patina that will last forever and prevent further corrosion. Brass on the other hand will continue to corrode with pitting no matter what the surface treatment is applied. It will eventually corrode away.
