What is copper extrusion?
Copper extrusions are solid straight strips with a certain cross-sectional shape and size after plastic processing materials with certain strength and toughness. Special-shaped copper bars are relative to common copper bars. The cross-sectional shape is not square or rectangular. There are various shapes, such as "L" type, "T" type, trapezoidal type, and multilateral polygonal type. Most of them are based on the manufacturer's specific product design requirements.
What are the advantages of copper extrusions?
Copper extrusions have good electrical conductivity, thermal conductivity, corrosion resistance and processability, smooth surface without wire drawing, precise size, high mechanical properties, high copper content, low oxygen content, dense structure, and free supply length.
Strong corrosion resistance: The surface of the copper profile has a layer of oxidation-resistant, corrosion-resistant copper layer, which can maintain a stable structure during application and is not easy to corrode.
Mechanical properties and good properties: copper extrusions have good mechanical properties and good properties, which can meet the needs of different applications.
Price stability: the price of copper extrusions is determined by the market, the market reflects the value of copper extrusions as tangible goods-related services. Copper on the market can bring great benefits to people's lives, and its service costs have become more obvious, so the price has become more reasonable.
What is the application of copper extrusions?
Copper extrusions have a wide range of applications in several fields.
In the field of electricity, copper extrusions are used as conductors for cables and wires because of their good electrical conductivity and corrosion resistance. In the field of light industry, copper and its alloys are used in the manufacture of a variety of light industrial products, such as brass, nautical brass, bronze, phosphor bronze, and white copper. In the field of machinery manufacturing, copper and its alloys are used in the manufacture of various machine parts, such as bearings, gears, pistons, pumps, and so on. In the field of construction industry, copper and its alloys are used in the manufacture of various architectural decorative materials, such as copper plates, copper pipes, copper windows, etc. In the field of defense industry, copper and its alloys are used in the manufacture of various military equipment and weapons, such as tanks, fighter jets, warships, and so on.
In addition, copper extrusions are also used as a variety of guide raw materials, such as cable rolled steel, etc., as well as used as resistance welding raw materials.
In short, the copper profile is a versatile material in different fields that can play its unique advantages.

| 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. |
