What are the types of copper materials? In fact, it can be simply divided into pure copper and alloy copper, pure copper is only copper elements, alloy copper is composed of two or more than two kinds of metal or non-metal synthesis of metal material.
A, pure copper
Pure copper is divided into anaerobic copper, red copper, phosphorus deoxidized copper.
1, oxygen copper copper purity is greater than 99.95%, due to high conductivity, stable processing performance, weldability, corrosion resistance and low temperature performance are good. Therefore, it is widely used in manufacturing busbar, conductive strip, waveguide, coaxial cable, vacuum seal, vacuum tube, transistor parts, etc.
2, copper, refers to more than 99.95% copper, must be only a very small amount of impurities, because the purity of copper is very high, therefore, the conductivity of copper compared with other materials of copper greatly reduced. Copper is widely used in the production of generators, busbars, cables, switching devices, transformers and other electrical equipment and heat exchanger
3, phosphorus deoxidized copper copper content of 99.90% or more, good welding performance and cold bending performance, widely used in the production of gasoline or gas conveying pipe, drain pipe, condensate pipe, water and electricity pipe, condenser, evaporator, heat exchanger, train car parts.
B, alloy copper
Alloy copper is mainly divided into brass, bronze, white copper, silver copper.
1, brass refers to copper and zinc based alloy, because of high strength, hardness, chemical corrosion resistance, so brass is widely used in the production of heat exchanger and condenser, low temperature pipeline, submarine transportation pipe. Manufacturing sheet, bar, bar, pipe, casting parts, etc.;
2. Bronze originally refers to copper-tin alloy. Due to its high strength, good sliding resistance, excellent cutting performance, good welding performance, and good corrosion resistance in atmosphere and fresh water, bronze is widely used in spring, reed and other elastic components and pipe fittings. Chemical instruments, wear-resistant parts and diamagnetic parts, and parts that bear friction in aviation, automobile, tractor and other industries; White copper is a copper based alloy with nickel as the main addition element. It has good ductility, high hardness, beautiful color, corrosion resistance and deep drawing performance. It is widely used in shipbuilding, petrochemical, electrical appliances, instruments, medical instruments, daily necessities, handicrafts and other fields, and is also an important resistance and thermocouple alloy.
3. White copper is an alloy of copper and nickel. The disadvantage of white copper is that the main added element -- nickel is a rare strategic material and its price is relatively expensive.
4. Silver copper is a binary alloy of silver and copper. Its outstanding characteristics are strong sulfide resistance, good electrical conductivity, fluidity and infiltration, good mechanical properties, high hardness, wear resistance and fusion welding resistance. Widely used in the production of air circuit breakers, voltage controllers, telephone relays, contactors, starters and other components of the contact, conductive ring and fixed contact. Vacuum solder, commutator, also can make coins, ornaments and tableware, etc.
Above is the answer about what types of copper materials, copper material is actually more widely used in daily life of a kind of metal material, almost covers all walks of life, Buck Copper production copper strip, copper tube, such as metal, not only is the brass plate factory, has rich experience in processing materials, non-standard customization, welcome to inquire to know if necessary.
