OCC是专有名词，代表大野连续铸造法(Ohno Continue Casting)。是有专利的，world-patented

在国内翻译OCC COPPER为单晶铜，OCC SILVER为单晶银。

单晶铜单晶银并非专有名词，也无专利，如果单从单晶铜翻译的话是one crystal copper,这个也可以简称说是OCC，所以此one crystal copper的简称OCC并非大野连续铸造法，所以给很多人混淆的感觉。

单晶说到底只是UPOCC线的一个特质而已，所以我们不可以等同，就象在国外人家不会说ONE CRYSTAL COPPER等同于OCC大野连续铸造法一样的。
所以在说到OCC线的时候，最好先问清楚这个OCC是大野连续铸造法还是只是单晶铜。

是的。OCC 的晶粒要大，说明结晶好，这些一般是用金相显微镜拍的。大学时我做过金相显微镜，测试制备样品很辛苦，拍照前要先打磨样品，磨得手都起泡了，同班女生有人打磨得都要哭了，工序复杂，要打磨1天多才能上镜拍照，显示打磨机器3遍打磨，至少需600个道次，然后手工打磨，每个不同的方向打磨200次，你要记得哪个方向已打磨过，千万别混淆了，否则重头再来。

没想到这个工序这么复杂，这下学习了，没想到付出这么多的努力。谢谢楼上顶帖，呵呵

日本人证书又没证明纯度是7N的，如果万隆把六个9说成是7N，那只能证明万隆也很无知，或者是故意在混淆视听，欺骗消费者。当然其实就算讲6N也一样是胡扯。

又在瞎混了，OCC既不能代表纯度，也不等于是单晶。严格的讲是还是多晶体的。

这个不叫瞎混，我说了OCC是代表大野连续铸造法。我只是叫别人不要把单晶铜和OCC大野连续铸造法等同。
你可以不认同别人的观点，但你不可以这样说别人，因为任何人没有审判别人的资格。除非你是法律赋予的。
我告诉你，这个世界上奸商很多，但绝对不是我。
我不想和你争吵，只是就事论事。

介绍你去看一下这里面的文章，很有意义。其实我们都是在走别人的路，OCC1986年就已经成专利了，比我仅小四岁而已，历经这么多年，中间很多故事，完全可以借鉴别人的东西来看待今天的事物，也许你要说我在抄袭，但这个是前车之鉴，可以让别人一劳永逸，这已体现自身的价值了。
看了以后我觉得现在的争吵争执毫无意义。我之所以继续发贴是想把我学到的和大家一起分享。168所有的烧友几乎都是我的前辈，包括比我小的，我喜欢音乐而已。我相信每个人心里都会有判断。

The Ohno Continuous Casting Process

As for conducting materials, normal, high purity copper has about 1500 grains in each foot (5000/m). The signal must cross the junctions between these grains 1500 times in order to travel through one foot of cable. These grain boundaries cause the same type of irritating distortion as current crossing from strand to strand.

The first grade above normal high purity copper is called Oxygen-Free High-Conductivity (OFHC) copper. In fact, this copper is not Oxygen-Free, it should more properly be called Oxygen-Reduced. OFHC is cast and drawn in a way that minimizes the oxygen content in the copper: approximately 40 PPM (parts per million) for OFHC compared to 235 PPM for normal copper. This drastically reduces the formation of copper oxides within the copper, substantially reducing the distortion caused by the grain boundaries. Additional improvement can be attributed to OFHC copper having longer grains (about 400 per foot), further reducing distortion. The sound of an OFHC copper cable is smoother, cleaner, and more dynamic than the same design made with standard high purity copper.

Not all OFHC is the same. If the poorest copper were given a value of one, and the best was a ten, then OFHC ranges from two to four-it is actually a range rather than a single performance level.

The next higher grade is an elongated grain copper sometimes called "linear-crystal" (LC-OFC) or "mono-crystal". These coppers have been carefully drawn in a process that results in only about 70 grains per foot. Cables using LC-OFC have an obvious audible advantage over cables using the same designs with OFHC.

In 1986 the Ohno Continuous Casting (OCC) process was introduced. The world patent "UP-OCC" (Ultra Pure Copper by Ohno Continuous Casting Process) was developed by professor Ohno of Chiba Institute of Technology in Japan. This technology has been applied to the manufacturing of single crystallized copper with the process of heated mold continuous casting. The resulting product are small rods of OCC pure copper, from which the wire can be drawn and which can have Copper grains of over 700 ft length.

Because of its characteristics of single crystal, unidirectional, free of impurity, flexible fatigue-resistance, corrosive-resistance, low electric resistance, none-crystal boundaries, rapid transmissibility, perfect in structure, and easy to process, all make it an ideal material for making rapid transmission lines. From inner hook up wires to interconnect cables, they can be widely applied to Hi-Tech products such as Hi-Fi stereo system, high resolution TV.

A couple of years later the "nines" race began. This refers to how many times the number "9" can be repeated when specifying a metal's purity. The prime contaminants in very high purity (99.997% pure, four nines) copper are silver, iron and sulfur, along with smaller amounts of antimony, aluminum and arsenic. The purity of OCC Copper can reach up to 99.9999% and even higher

But with OFHC and OCC, the nomenclature "six nines" or "eight nines" has almost no meaning. All else being equal, higher purity is a straight forward benefit. However, grain structure, softness and surface finish can each make more difference than a "nine" or two. Then there is the matter of measurable purity. Due to contamination caused by the measuring process, there is a serious question as to whether any metal can be verified as having greater than six nines purity. Also, since "nines" became a selling point, some quite absurd and dubious claims have been made. Let the ears beware.
