Oxygen-free copper, often referred to as OFHC (Oxygen-Free High Conductivity) copper, is an ultra-pure form of copper with an oxygen content of less than 0.001%. It is one of the purest commercially available copper materials. The low oxygen concentration enhances electrical and thermal conductivity, increases corrosion resistance, and reduces the risk of hydrogen embrittlement. Due to these properties, it is widely used in electronics, high-frequency applications, vacuum technology, and other industries requiring high-purity materials.
