The characteristics of each grade material and the fields of use
Item | Characteristic | Fields of application |
C11000 | It has good electrical conductivity, thermal conductivity, corrosion resistance and processing properties, and can be welded and brazing. Impurities containing reduced electrical and thermal conductivity are small, and trace amounts of oxygen have little effect on electrical conductivity, thermal conductivity and processing properties, but it is easy to cause "hydrogen disease", and it is not easy to process (annealing, welding, etc.) and use in a high temperature (such as 370 °C) reducing atmosphere. | Used in electrical, thermally conductive and corrosion-resistant equipment. Such as: wires, cables, conductive screws, detonators for blasting, chemical evaporators, storage devices and various pipelines |
C10200、C10300 | It has high purity, excellent electrical and thermal conductivity, no "hydrogen disease" or very little "ammonia disease" (no hydrogen embrittlement), good processing performance and welding, corrosion resistance and cold resistance | It is mainly used as electric vacuum instrumentation devices, various hardware products, lamps, pipe fittings, zippers, plaques, rivets, springs, settlement filters, etc |
C12000 | Its welding performance and cold bending performance are good, generally no "hydrogen disease" tendency, can be processed and used in a reducing atmosphere, but not suitable for processing and use in an oxidizing atmosphere. The residual phosphorus content of C12000 is less than that of C12200, so its electrical and thermal conductivity is higher than that of C12200. | It is mainly used in pipes, but can also be supplied as plates, strips or rods and wires. Used as gasoline or gas transmission pipes, drain pipes, condensation pipes, mine pipes, condensers, evaporators, heat exchangers, train car parts. |

Q1
What is the difference between disc copper busbar and cable?
Answer: Copper discs and cables are both conductive materials in electrical systems, but they differ in structure, purpose and conductive properties. Disk-type copper bars are in disk or roll shape and are mainly used for connection and conduction of electrical equipment such as bus ducts and switch cabinets. Cables are composite structures composed of conductors, insulation layers and protective layers, used to transmit electrical energy or signals. In terms of electrical conductivity, disc copper bars have higher conductivity and are suitable for large current transmission; while cables are suitable for smaller current transmission.
Q2
What is the electrical conductivity of disc copper bars?
Answer: Disk-type copper busbars have excellent electrical conductivity, and their electrical conductivity is second only to silver. This allows the disc copper bar to effectively transmit current in the electrical system and reduce energy loss.
Q3
What factors affect the price of disc copper busbars?
Answer: The price of disc copper bars is mainly affected by factors such as copper prices, processing costs, and market supply and demand. Fluctuations in copper prices will directly affect the cost and selling price of disc copper bars. In addition, factors such as processing costs and increases or decreases in market demand will also have an impact on the price of disc copper bars.
Q4
Can disc copper busbars be recycled and reused?
Answer: Yes, copper discs can be recycled and reused. Scrap copper discs can be processed through smelting and refining processes to obtain pure liquid copper, which can then be recast into new disc copper bars. Recycling and reusing copper plate busbars is not only beneficial to resource conservation and environmental protection, but also reduces production costs.
Q5
How to test the quality of disc copper busbars?
Answer: The quality of disc copper busbars can be tested through various methods such as visual inspection, conductive performance testing, and mechanical performance testing. The appearance inspection mainly observes whether the surface of the copper bar is flat and smooth, and whether there are defects such as cracks and inclusions. The conductive performance test evaluates the conductive performance of the copper bar by measuring its resistivity. Mechanical performance testing tests the strength, plasticity and other performance indicators of the copper strip through tensile tests, bending tests and other methods.
