An alloy consisting of pure copper as a base with the addition of one or more other elements. Pure copper is purple red, also known as red copper. The density of pure copper is 8.96, and the melting point is 1083℃. It has excellent electrical conductivity, thermal conductivity, ductility and corrosion resistance. Mainly used for making generators, busbars, cables, switching devices, transformers and other electrical equipment and heat conduction equipment such as heat exchanger, pipe, solar heating device plate collector. Commonly used copper alloys are divided into brass, bronze and white copper.
Copper alloys can be classified in three ways:
According to the alloy
According to the alloy system, it can be divided into non-alloyed copper and alloyed copper. Non-alloy copper includes high purity copper, tough copper, deoxidized copper, anaerobic copper and so on. Customarily, non-alloy copper is called red copper or pure copper, also called red copper, and other copper alloys belong to alloy copper. In China and Russia, alloying copper is divided into brass, bronze and white copper, and then divided into small alloying series in a large class.
According to the function
By function, A thermally conductive copper alloy (mainly the alloying and microalloyed copper), structure with copper alloy (including almost all the copper alloy), corrosion resisting copper alloys, tin, brass, aluminum, brass, various main titanium white brass, aluminum bronze, bronze, etc.) not wear-resistant copper alloy (mainly including elements such as lead, tin, aluminum, manganese complex brass, aluminum bronze, etc.), free cutting copper alloy, copper, lead, copper - Tellurium, copper-antimony alloy), elastic copper alloy (mainly antimony bronze, aluminum bronze, beryllium bronze, titanium bronze, etc.), damping copper alloy (high manganese copper alloy, etc.), art copper alloy (pure copper, simple copper, tin bronze, aluminum bronze, white copper, etc.). Obviously, many copper alloys are polygenic.
Material formation method
According to the material forming method, it can be divided into casting copper alloy and deformation copper alloy. In fact, many copper alloys can be used for both casting and deformation. In general, deformed copper alloys can be used for casting, but many cast copper alloys cannot be forged, extruded, deep drawn and other deformation processing. Cast copper alloys and deformed copper alloys can be subdivided into cast copper, brass, bronze and white copper.
