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.
