Abstract

A metal article comprises two metals, and a first hole and an oxide layer are set correspondingly on the surfaces of the two metals. To avoid the electrolytic corrosion on the interface between the two metals during the formation of the first hole, the disclosure provides a method of manufacturing the metal article. By putting a metal substrate in a first electrolyte including an etching agent and a passivating agent and applying electricity on the metal substrate, the metal article with the first hole is formed without electrolytic corrosion. The disclosure also provides a metal composite, which is formed by setting a material part in the first hole of the metal article.
