What is the copper rod?
Copper rods refer to solid copper rods that have been extruded or drawn. Different types of copper rods have different molding processes and have different characteristics. Copper rod is a kind of non-ferrous metal processing rod which has good processing performance and high electrical conductivity. Mainly divided into brass rods (copper-zinc alloy, cheaper) and copper rods (higher copper content).
What are the advantages of copper rods?
Copper rod has good electrical conductivity, thermal conductivity, corrosion resistance, processing performance, smooth and straight surface (no straightening marks), accurate size, high electrical conductivity, and excellent mechanical properties.
High strength: copper rod has good mechanical properties, high tensile strength, and can withstand greater pressure and tensile force to a certain extent.
Corrosion resistance: Copper rods have certain corrosion resistance in common corrosive environments such as acid and alkali and are not easily rust or be eroded by other chemicals.
Good thermal conductivity: Copper rods have high thermal conductivity and can play a good role in heat transfer.
Excellent electrical properties: copper rods have good electrical properties, such as transmitting large currents in electrical conductors.
Good processability: copper rods can be processed by cold working, hot processing, and other ways, such as sawing, cutting, drilling, milling, drawing, etc., and the processing technology is relatively mature.
Wide range of applications: copper rods are widely used in machinery manufacturing, construction, transportation, electronic communications, instrumentation, and other fields.
What is the application of copper rods?
Copper rod is used in the electrical industry, new energy charging piles, electricians, electrical appliances, power transmission and transformation, molds, hardware processing, and other industries. It is a high-quality conductive material for various high and low-voltage electrical accessories.
Mechanical manufacturing: Copper rods are also widely used in mechanical manufacturing. Copper has good processing performance and corrosion resistance, so that copper rods can be made into various mechanical parts, such as bearings, gears, nuts, bolts, etc.
Construction industry: Copper rods also have certain applications in the construction industry. Due to copper's aesthetics and corrosion resistance, copper rods can be made into various building decoration materials, such as door handles, windows, roofs, walls, etc.
Chemical industry: Copper rod also has certain applications in the chemical industry. Due to copper's corrosion resistance and thermal conductivity, copper rods can be made into various chemical equipment, such as reactors, heat exchangers, distillation columns, etc.

| 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. |
