Description
The classification of the copper
Pure copper
Pure copper is called red copper, also known as red copper, it has
good plasticity, excellent electrical conductivity, thermal
conductivity, can be applied to hot pressing, cold pressing
processing, widely used in cable, wire, electric spark special
corrosion copper and other products.
The brass
Brass refers to the alloy of zinc and copper, also can be divided
into ordinary brass and special brass. Ordinary brass with *9% zinc
content as the dividing line, less than *9%, good plasticity,
usually suitable for hot and cold compression processing. More than
*9%, suitable for hot pressing.
Copper
Red copper is copper with a high content of copper, the total
content of other impurities is less than 1%, the density is 8.*6,
melting point is ***3℃. According to the composition, Chinese
copper processing materials can be divided into four categories:
ordinary copper (T1, T2, T3, T4), oxygen-free copper (TU1, TU2 and
high purity, vacuum oxygen-free copper), deoxidized copper (TUP,
TUMn), and special copper with a small amount of alloying elements
(arsenic-copper, telluric-copper, silver-copper).
Bronze
Bronze refers to copper base alloy except copper nickel, copper
zinc alloy, the main varieties are tin bronze, aluminum bronze,
special bronze (also known as high copper alloy)
Cupronickel
White copper, namely nickel as the main element of the copper
alloy. Cu-ni binary alloy is called ordinary white copper; And
white copper is divided into ordinary copper nickel binary alloy,
and added iron, zinc, aluminum, manganese complex white copper.
Tungsten copper
Tungsten copper alloy has a wide range of applications, mainly used
to manufacture arc ablation resistant high voltage switch contacts
and rocket nozzle throat lining, tail rudder and other high
temperature components, but also used for electrical processing
electrode, high temperature mold and other requirements of
electrical conductivity and high temperature use.
