Under the same conditions of other materials, the single crystal copper version of the transformer not only has several times better performance than the OFC oxygen-free copper. In the actual audio equipment, it is far away from other audio transformers, and the low-frequency deep space sense. , the high-frequency and elegant, high-frequency elegant, full frequency band
The embodiment is vivid. This kind of change is a lot of money, and it can't be done by transforming many equipment lines!
OFC oxygen free copper
TPC
Oxygen-free copper, pure copper that does not contain oxygen or any deoxidizer residue.
But in fact it still contains a very small amount of oxygen and some impurities. According to the standard, the oxygen content is not more than 0.003%, the total impurity content is not more than 0.05%, and the purity of copper is greater than 99.95%. In the popular industrial electronic products, it has a high cost performance.
Single crystal copper
PCOCC
Single crystal copper is a kind of high-purity oxygen-free copper. The whole copper rod consists of only one crystal grain, and there is no “grain boundary” between the crystal grains (“grain boundary” will reflect the passing signal and Refraction, resulting in signal distortion and attenuation), resulting in extremely high signal transmission performance. Its purity is above 99.9999% 6N).
Single crystal copper is a conductor technology manufactured by "high temperature hot casting mode continuous casting method". Because the casting process is specially heated, a single crystal copper conductor can be obtained, and each crystal can extend for hundreds of meters or more. There is only one crystal grain in the length of the application, and there is no so-called "grain interface". In the signal transmission, it is not necessary to pass the "grain boundary" between the grain and the grain, and the signal is more easy to penetrate and conduct. Very low loss, it is a perfect wire. Its physical properties are close to silver.
There are three characteristics:
1. The purity of single crystal copper reaches 99.9999%
2. Resistance is 8%–13% lower than ordinary copper
3. The toughness is extremely high. The ordinary copper material is twisted 16 times, and the single crystal copper material can be twisted 116 times.
The use of single crystal copper products in the audio video industry has become a top material for producing high-fidelity audio and video signals, high-frequency digital signal transmission cables and ultra-fine filaments for the microelectronics industry. It can be used in mobile phones, audio, computers, etc. Electronic devices perform better, are smaller, and last longer. When various audio and video signals pass through the grain boundary during transmission, reflection and refraction will occur, which will cause signal distortion and distortion attenuation. However, the crystal grain boundary or crystal grain boundary of single crystal copper will fundamentally improve the transmission quality. Therefore, single crystal copper has been widely used in audio and video signal transmission.

Regarding the role of the audio transformer and the results of the audio transformers we produce, we believe that customers who have used our R series of input transformers are more aware. The main function of the transformer is to isolate and eliminate the digital sound of the digital sound source. The sound is pure and delicate, the oil is lustrous, the middle and high sounds are soft and transparent, the details are rich, the bass is thick and powerful, and the sound field is deep and the sound is very resistant. It has a LP vinyl record player. It is like a charm, which makes people listen to it.
