Copper C102, called Oxygen-Free Copper (OFC), is a high-purity copper alloy with a minimum copper content of 99.99%. Unlike standard copper alloys, Copper C102 is produced through an oxygen-free process, eliminating residual oxygen and significantly improving its electrical conductivity and corrosion resistance. The result is an alloy that offers superior performance, particularly in high-precision applications with critical conductivity and reliability.
Copper C102 (Oxygen-Free Copper) is used in applications that require exceptional electrical and thermal conductivity, such as electrical power cables, connectors, and electronic components. It is especially favored in telecommunications, aerospace, and automotive industries, where high-performance materials are essential for efficiency and durability. Due to its excellent characteristics, Copper C102 is often selected for CNC Machining Service and used in producing CNC Machined Copper Parts in various applications.
