Copper Alloy 101 (C10100)
Oxygen-Free Electronic Copper (OFE)
Copper Alloy C101, also known as Oxygen-Free Electronic Copper (OFE), is one of the purest forms of copper available, with a minimum copper content of 99.99%. It is specifically refined to contain minimal oxygen and trace impurities, making it ideal for critical electrical and thermal applications that demand exceptional conductivity and reliability.
