Resistant Metals Copper is often associated with noble metals for its resistance to nonoxidizing acids like muriatic hydrochloric acid Copper is a not a noble metal per se like mercury sliver or gold though it displays some of their properties in that copper will resist the degenerative reactions of muriatic acid in the absence of a catalyst
