Oxygen-free copper boasts an exceptionally high copper content of approximately 99.95%, which delivers outstanding electrical and thermal conductivity. Often referred to as high conductivity (HC) copper, this grade also exhibits excellent ductility, strong impact resistance, durability, and superior corrosion resistance, making it ideal for demanding electrical and thermal applications.
Copper C110, also known as UNS C11000 or CDA 110, contains slightly less purity than Copper 101 but still offers an impressive 99.90% copper content. This grade is more cost-effective and easier to machine compared to higher-purity coppers, making it a popular choice for a wide range of electrical applications. Typical uses include overhead power conductors, coaxial cables, wiring harnesses, and generator windings.
Pure copper is an exceptional material widely used in CNC machining services due to its outstanding electrical and thermal conductivity. These properties make copper the preferred choice for manufacturing components in electronics, electrical connectors, heat exchangers, and cooling systems where efficient heat dissipation and electrical performance are crucial. Copper's excellent machinability enables precise CNC milling, turning, and drilling with fine detail and smooth surface finishes, ensuring high-quality parts. Additionally, copper has good corrosion resistance and natural antimicrobial properties, which extend its application to medical devices and sanitary equipment. Despite its softness compared to other metals, advanced CNC techniques allow for effective machining of pure copper while maintaining dimensional accuracy and repeatability.
