PCOCC就見過,PCOCC先係單結晶無氧銅

PCOCC = ESCOCC = OCC...... everything with xxxOCC is the same, PCOCC is the very first OCC use by Audio Technica, they name it "PC"OCC base on the name of the developer, ESCOCC is use by Denko, they name themselves as "ESC"OCC for marketing purpose, same apply to alll other "What's"OCC.
There is also SPCOCC (Silver Plated Copper OCC), as long as the main material is single crystal copper, anyone can name themselves xxxOCC.

其實 所謂什麽“單晶銅” “單晶銀”， 廿年前已經有喇！ 不過戈陣時有 patent。 如今 patent 過晒 ...

No, the patent only no more exclusive for onr party, open to anyone as long as thy can make OCC specifications, but there is still a patent.

OCC 既purity已經上到去99.9999%
Oxygen 已經得返0.0001%以下
再落去有意思嗎?

Minimum purity of OCC is 5N, right now the technology can't manufacturing OCC over 6N, even Nexxxch 7N is only almost 7N, not real 7N, however, non-OCC copper maxiumu purity now can reach real 8N, therefore there is still room for improve.

China can manufacturing OCC for over 10 years, but before mostly export or OEM only, now due to national commercial situation, export business no good, many OEM muafacutrer try to make direct sales, that's why recent years so many China made OCC appear.
OCC is nothing expensive or difficult, but China made OCC may not 100% up to standard due to QC, such as one 300M reel of cable may not all 300M is OOC, maybe 50M not QC pass but they don't cut and throw away, however, that 50M is still very high purity OFC, only not reach the OCC standrad.
Famous brand OCC in reel, mostly not sell in large reel, this is because for example a whole pc of 1000M wire will have some percentages of length/crystal can't form into OCC.

Ceramics is another topic, AT also have Titan, they are just mixed some other material into the insulator for anti-resonance or shielding purpose, nothing related to the conductors.

所謂PCOCC，就是使用專利的大野連續鑄造法，用很慢的速度連續抽銅，讓銅的結晶變得非常大，單一結晶的長度可以超過200公尺以上，當應用在一般音響線材上面時，整條線的銅導體都在「單一結晶」當中，也就是說PCOCC沒有傳統銅線的結晶縫隙，訊號傳導就更純淨。
