mixedmetal

Mixed metal is a broad term used to describe materials composed of two or more metallic elements. It covers both alloys, in which elements are dissolved to form a single homogeneous solid solution, and layered or bonded metal systems, where different metals are joined but retain some distinct identity.

Common examples of mixed metals in metallurgy include brass (copper and zinc), bronze (copper and tin), and various steel alloys (iron combined with carbon and other elements). Multimetal designs also include bimetallic or multilayer assemblies in which two metals are joined as separate layers or components.

In jewelry and decorative work, mixed-metal pieces pair colors and textures by combining gold, silver, copper, and other metals through inlay, overlay, forging, brazing, or electroplating. These techniques create contrast and can improve wear resistance or reduce cost.

Properties of mixed metals depend on composition and structure. They can offer higher strength, improved hardness, or enhanced corrosion resistance compared with a pure metal, but may also introduce incompatibilities such as different melting points or galvanic corrosion if not properly designed.

Applications range from cookware and architectural hardware to electronic packages and industrial components, where cladding or layered structures provide a combination of surface properties and bulk performance.
