Abstract
A corrosion-resistant coated brass metal coated with a corrosion resistant alloy. The corrosion resistant alloy is a tin metal alloy or a tin and zinc metal alloy. The corrosion resistant metal alloy may also include one or more metal additives to improve the coating process and/or to alter the properties of the tin or tin and zinc metal alloy.
