Oxygen-free copper
Encyclopedia : O : OX : OXY : Oxygen-free copper
Oxygen-free copper, commonly abbreviated as OFC, is a manufacturing process of copper cables. The process produces more pure copper, resulting in slightly higher conductivity than cables manufactured from unprocessed copper.
A variation of the oxygen-free copper manufacturing process called linear crystal oxygen-free copper, abbreviated LC-OFC, also increases purity between crystal boundaries, resulting in longer crystallites (grains) and therefore lower resistance.
These kinds of cables are often used in high-end audio equipment and other fields where retention of analog signal is important.
