What is the difference between OFC copper and OCC copper?

What is the difference between OFC copper and OCC copper?

OCC copper, on the other hand, is known for its exceptional purity and crystal structure. The OCC process involves single crystallization, where copper is melted and then slowly cooled to form a single crystal structure. This method eliminates the grain boundaries found in traditional copper, resulting in a material with excellent electrical conductivity and signal transmission capabilities. OCC copper typically has a minimum conductivity of 99.99%, making it ideal for high-end audio cables that require superior performance.
