1. I feel that according to China's regulatory regulations, all token projects are operated in violation of regulations, let alone legal. Financial management is risky and investment needs to be cautious. It is suggested to choose legal and formal financial management projects.
2. Less money is not enough to waste time
3. Each has its own characteristics, properties and uses
OFC (oxygen free copper): refers to copper with purity greater than 99.95%, oxygen content less than 0.003% and total impurity content less than 0.05%. OCC (single crystal oxygen free copper): refers to the single crystalline copper with purity of more than 99.996% and manufactured by "high temperature hot casting mode continuous casting method". Single crystal copper is further classified into pc-occ and up-occ
single crystal copper (OCC) is a kind of high-purity oxygen free copper. The whole copper rod is composed of only one grain, and there is no "grain boundary" between the grains (the "grain boundary" will reflect and refract the passing signal, causing signal distortion and attenuation), so it has very high signal transmission performance
oxygen free copper (OFC) literally means pure copper without oxygen or any deoxidizer resie. However, according to the oxygen content, oxygen free copper can be divided into No.1 and No.2. The purity of No.1 is 99.97%, the oxygen content is not more than 0.003%, and the total impurity content is not more than 0.03%; The purity of No.2 oxygen free copper is 99.95%, the oxygen content is not more than 0.003%, the total impurity content is not more than 0.003%, and the total impurity content is not more than 0.05%
the wire is not made of one copper. Cutting the wire, we can see that it is generally composed of three strands of wires, each of which is composed of several strands of copper wire, and each layer is separated by an insulating layer. Because of the content of copper, the resistance of single crystal copper is lower than that of ordinary copper, and its toughness is very high. Ordinary copper is broken when it is twisted for 16 turns, and single crystal copper can be twisted for 116 turns.
4. Pure copper without oxygen or any deoxidizer resie. But in fact, it still contains a very small amount of oxygen and some impurities. According to the standard, the content of oxygen is not more than 0.03%, the total content of impurities is not more than 0.05%, and the purity of copper is more than 99.95%
according to the oxygen content and impurity content, oxygen free copper can be divided into No.1 and No.2 oxygen free copper. The purity of No.1 oxygen free copper is 99.97%, the oxygen content is not more than 0.003%, and the total impurity content is not more than 0.03%; The purity of No.2 oxygen free copper is 99.95%, the oxygen content is not more than 0.003%, and the total impurity content is not more than 0.05%
oxygen free copper has no hydrogen embrittlement, high conctivity, good processability, weldability, corrosion resistance and low temperature performance
OFC (oxygen free copper): metallic copper with purity of 99.995%. Generally used in audio equipment, vacuum electronic devices, cables and other electrical and electronic applications. Among the oxygen free copper, lc-ofc (linear crystalline oxygen free copper or crystalline oxygen free copper): purity is more than 99.995%, and OCC (single crystal oxygen free copper): purity is the highest, more than 99.996%, which is also divided into pc-occ and up-occ
the single crystal oxygen free copper made by up-occ Technology (ultra pure copper by Ohno Continuous Casting Process) has no directivity, high purity, anti-corrosion and extremely low electrical impedance, which makes the wire suitable for high-speed and high-quality signal transmission.
5. First of all, I will tell you that metals are all crystals. Crystal results are mainly unit cells. Their structures include body centered cubic, face centered cubic, and close packed cubic
according to its purity, there are 4N, 5N, 6N, 7n, 8N, etc., in which n stands for 9 (nine), 4N means its purity is more than 99.99%, and so on

according to different smelting methods, high purity copper can be divided into OFC oxygen free copper, lcofc copper, pcocc oxygen free single crystal copper, super pcocc copper, etc

OFC is the abbreviation of oxygen free copper, which is called oxygen free copper in Chinese. It is the copper wire proced in the process of copper smelting because no oxide is added and oxidation is avoided. The purity is 99.995%. Generally speaking, it is a very good conctor material

LC OFC copper is proced by special wire drawing process, which makes the crystal particles of oxygen free copper larger to increase the conctivity. The crystal number of 1 m long LC OFC copper is about 20, and its purity is slightly higher than that of OFC oxygen free copper, but it is still in the range of 4N. However, the
conctivity of LC OFC copper junction is better than that of OFC copper junction because of less crystal particles

the full name of OCC is Ohno Continuous Casting, which is a conctor technology invented by Professor Ohno of Japan University of technology in 1989. Because the casting process is specially heated, single crystalline conctor can be obtained, and each crystal can extend for hundreds of meters, In the practical application, there is only one crystal grain, and there is no so-called "grain boundary". When the signal is transmitted, there is no need to pass through the "grain boundary" between grains. The signal is easier to penetrate and conct, so the loss is very low

PC OCC copper is abbreviated from pure copper by Ohno Continuous casting process, which refers to high-purity crystalline copper proced by OCC casting process. This casting technology, developed by Professor Ono of Chiba University of technology in Japan, is characterized by the extraction of metal wire from hot-melt metal (such as extracting molten copper into copper wire), rapid cooling by cooling water and removal of impurities, so as to obtain single crystal metal. High purity copper wire drawn by OCC smelting method is PC OCC. If the diameter of copper wire is less than 0.3mm, the length of crystal can reach 125m, the overall copper purity can be improved to 99.996%, and the conctivity is even better

I'm a student of Kunming University of science and technology. I don't want to help you. I only give you 10 points of wealth value. In order to help you learn some knowledge, it depends on your RP if you don't add more points
