Why oxygen free copper? What does it do?

<> "Oxygen-free copper rods should be divided into ordinary oxygen-free copper rods and high-purity oxygen-free copper rods. Ordinary oxygen-free copper rod is smelted in the power frequency iron-core induction furnace, and the smelting of high-purity oxygen-free copper rod is carried out in the vacuum induction furnace, and the smelting of oxygen-free copper rod should be made of high-quality cathode copper as raw material. High-purity oxygen-free copper rod should be made of high-purity copper cathode as raw material.

Scope of application: high purity, excellent electrical and thermal conductivity, no "hydrogen disease" or very little "hydrogen disease"; The processing performance and welding, corrosion resistance and corrosion resistance are good.

Smelting method: When the ordinary oxygen-free copper rod adopts the semi-continuous casting method, the refining process of the melt in the melting furnace and holding furnace can be free from time constraints. Continuous casting is different, the quality of the molten copper depends not only on the refining quality of the melting furnace and holding furnace, but more importantly, on the stability of the whole system and the whole process.

Oxygen-free copper is further divided into No. 1 and No. 2 oxygen-free copper. The purity of No. 1 oxygen-free copper is reached, the oxygen content is not greater than, and the total impurity content is not greater than; The purity of No. 2 oxygen-free copper is reached, the oxygen content is not greater than, and the total impurity content is not greater than.

Intensity: ( b, n mm ) 275 Oxygen-free copper density:

Pure copper that does not contain oxygen and does not contain any oxygen absorber residues. But in fact, it still contains very trace amounts of oxygen and some impurities. According to the standard, the content of oxygen is not greater, the total content of impurities is not greater than that, and the purity of copper is greater than that.

Oxygen-free copper products are mainly used in the electronics industry. It is often made of oxygen-free copper plates, oxygen-free copper strips, oxygen-free copper wires and other copper materials. Oxygen-free copper has no hydrogen embrittlement, high electrical conductivity, good processing performance, welding performance, corrosion resistance and low temperature performance.

The standards for oxygen content are not exactly the same in different countries, and there are certain differences. OFC (oxygen-free copper): Copper of the metal with a purity of .

It is generally used in electrical and electronic applications such as audio equipment, vacuum electronics, and cables. Among them, there are LC-OFC (linear crystalline oxygen-free copper or crystalline oxygen-free copper): the purity is above and OCC (single crystal oxygen-free copper):

The purity is the highest, and in the above, it is divided into PC-OCC and UP-OCC. Oxygen-free copper is a single crystalline oxygen-free copper made of UP-OCC technology (Ultra Pure Copper by Ohno Continuous Casting Process), which is non-directional, high-purity, anti-corrosion, and extremely low electrical impedance, making the wire suitable for high-speed and high-quality transmission signals.

Hello, oxygen-free copper refers to pure copper that does not contain oxygen and does not contain any oxygen absorber residues! But in fact, it still contains very trace amounts of oxygen and some impurities. According to the standard, the content of oxygen is not greater, the total content of impurities is not greater than that, and the purity of copper is greater than that.

Hope, thank you!

1.Purity is different: Pure copper does not contain oxygen or any deoxidizer residues, but still contains a very small amount of oxygen and some impurities.

Oxygen-free copper is divided into No. 1 and No. 2 oxygen-free copper. The purity of No. 1 oxygen-free copper is reached, the oxygen content is not greater than, and the total impurity content is not greater than; The purity of No. 2 oxygen-free copper is reached, the oxygen content is not greater than, and the total impurity content is not greater than. 2.

Different characteristics: oxygen-free copper has high conductivity, good processing performance, welding performance, corrosion resistance and low temperature performance. Pure copper has good electrical conductivity, thermal conductivity, corrosion resistance, and solderability.

3.Different uses: Pure copper has a much wider range of uses than iron.

Every year, the electrical industry uses a large amount of copper. Pure copper is mainly used in the manufacture of electrical equipment such as generators, busbars, cables, switchgear, transformers, as well as other heat conduction equipment such as heat exchangers, pipes, flat plate collectors for solar heating devices. Oxygen-free copper is widely used in the electronics industry.

Among vacuum electronics, oxygen-free copper ranks first among the seven structural materials in the field. It is often used in the manufacture of magnetic instruments that must be protected from magnetic interference, such as compasses, aviation instruments, etc. Excellent plasticity, easy to hot and cold pressing, can be made into tubes, rods, wires, belts, strips, plates, foils and other copper materials.

Data: Oxygen-free copper can be divided into ordinary oxygen-free copper and high-purity oxygen-free copper. Ordinary oxygen-free copper can be smelted in a power-frequency induction furnace with an iron core, while high-purity oxygen-free copper can be smelted in a vacuum induction furnace.

Pure copper is purple from the inside out, so it is called copper. For some wires, the color of the container can be checked from the outside. Usually the outer layer is scraped off, or the cross-section is observed.

It is likely that it is pure copper with a copper color inside and out.

Copper is the element of copper. It gets its name because of its purplish red color.

Copper gets its name from its purplish red color. It is not necessarily pure copper, and sometimes a small amount of deoxidizing or other elements is added to improve the material and performance, so it is also classified as a copper alloy. According to the composition, China's copper processing materials can be divided into:

There are four types of 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 (arsenic copper, tellurium copper, silver copper) with a small amount of alloying elements. The electrical conductivity and thermal conductivity of copper are second only to silver, and they are widely used in the manufacture of conductive and thermally conductive equipment.

OFC (oxygen-free copper): Copper of the metal with a purity of .

It is generally used in audio equipment, vacuum electronics, and cables.

and other electrical and electronic applications.

Among them oxygen-free copper.

There is also LC-OFC (Linear Crystalline Oxygen-Free Copper or Crystalline Oxygen-Free Copper): the purity is above.

and OCC (single crystal oxygen-free copper): the highest purity, in the above, it is divided into PC-OCC and UP-OCC, etc.

1. The purity is different. Pure copper is oxygen-free, and oxygen-free copper contains a very small amount of oxygen; 2. The characteristics are different. Oxygen-free copper has high conductivity, good processing and welding performance, corrosion resistance and low temperature performance.

Pure copper has good electrical conductivity and thermal conductivity, very good corrosion resistance, and good weldability. 3. Different uses.

Oxygen-free copper is mostly used in electrical and electronic equipment such as audio equipment, vacuum electronics, and cables. Pure copper is widely used in the production of conductive and thermally conductive equipment; It can be processed into various semi-finished products and finished products by cold and thermoplastic processing for use in the chemical industry.
