UP-OCC is an innovative process used to produce silver and copper wire, developed and patented by Professor Ohno from the Chiba Institute of Technology in Japan. This unique technique has been widely used in the audio industry to manufacture cable products.


Ohno Continuous Casting (O.C.C.) involves the usage of heated moulds that draw out a single crystal up to 125 meters in length, a procedure that almost eliminates grain boundaries and other impurities from the copper or silver. Thus, O.C.C. copper and silver offer a superior single-long crystal structure and negligible oxides or other contaminants. In comparison, OFC (Oxygen-Free Copper) consists of many grain boundaries and impurities and has approximately 400 crystals per foot.


UP-OCC has many benefits, including a non-corroding, pure, unidirectional single crystal, flexibility and fatigue resistance, low electrical resistance, rapid signal transmission, no crystal boundaries, and far superior performance.


The continuous casting of single-crystal production has existed since the '80s. Since then, many refinements have been made to perfect the casting process in order to improve purity and efficiency, yet, to this day, most factories still use old techniques and outdated machinery to produce O.C.C. wire, resulting in an inferior quality and lower-purity O.C.C. wire, which is the most commonly used O.C.C. wire by cable companies based in China and cheap custom-cables typically sold on AliExpress, eBay, and Etsy. 


How does Arctic deliver the most cutting-edge and highest-purity O.C.C. silver and copper on the market?

We produce our O.C.C. wire in exceptionally small batches to preserve its purity in a state-of-the-art factory capable of casting small-diameter copper and silver rods much more efficiently, resulting in an extremely high-purity wire at a bearable cost. 


Each of our O.C.C. wires is uniquely designed to our exact specifications. Our custom 'ultraflex' TPU insulation is flexible, soft, and crystal clear. Each wire strand is shielded by enamel coating, eliminating the risk of oxidation and corrosion and ensuring longevity.

Our latest custom type-4 and type-6 Litz O.C.C. wire utilizes a complex 7-group design; each group contains a specific count of ultra-fine enameled strands with an infused mix of kevlar and fine Japanese cotton central core. 

Are OCC copper and silver cables sold by other companies for thousands of dollars higher quality or offer better performance? 
Not in the slightest. In fact, in most cases, our custom cables are superior in every way at a fraction of the cost. 

Many companies sell excessively overpriced cables to cover their aggressive marketing costs and to be able to provide dealer prices to their distributors so they can maintain MSRP.  Arctic sells its custom cables directly to customers and works on much lower margins.
