Coatings & finishing
Coating and finishing of metal can have a major impact on its long term success and appearance. Steel is normally galvanized using a similar process, in which iron is ground up and mixed with a chemical agent, usually zinc, to form steel. Brass will cure to this form over time, but copper, aluminum, or titanium may need to be heated and subsequently tempered to achieve this. Brass does not rust naturally, but it does produce flaking, which can be reduced with the application of an acid, but also helps increase its cost.
