OFHC
OFHC stands for Oxygen-Free High Conductivity copper. It is a type of high-purity copper characterized by extremely low levels of oxygen, typically less than 0.001%. This high purity is achieved through specialized melting and casting processes, often under vacuum or an inert atmosphere. The absence of oxygen and other impurities significantly enhances its electrical and thermal conductivity.
OFHC copper possesses electrical conductivity typically around 100% IACS (International Annealed Copper Standard), meaning its conductivity
Due to its superior electrical and thermal properties, OFHC copper is widely used in demanding applications.
