Products Description
C10100, also known as OFE (Oxygen-Free Electronic) Copper, is produced through a refining process that eliminates nearly all oxygen, resulting in an extremely low oxygen content of less than 10 ppm. This makes it ideal for applications that cannot tolerate hydrogen embrittlement or electrical losses. Power distribution, bus bars, semiconductor fabrication, and vacuum environments typically use the tubes when purity and performance are crucial.
We produce and provide a range of options, such as Copper C10100 Rectangular Tube, C10100 Copper Round Tube, C10100 Copper Square Tube, and Copper C10100 Oval Tube, ensuring versatility for various structural or fluid handling applications. Available sizes vary from 6mm to 150mm in outer diameter, with wall thicknesses between 0.5mm and 6mm and lengths extending up to 6 meters. We offer customized dimensions and tolerances to meet OEM and specialized needs.
We could draw and test our Seamless Copper C10100 Tube ASTM B152 products to guarantee precise dimensions, smooth internal finishes, and consistent grain structures. These qualities are essential for critical applications in electronics and precision assemblies. We also offer C10100 Copper Tubing for Electrical Applications, which has excellent conductivity (at least 101% IACS) to reduce energy loss and improve performance in power transmission or grounding systems.
Our Oxygen-Free Copper C10100 Tube is the perfect choice for designs that require copper tubing with extremely low impurity levels and exceptional conductivity. It ensures mechanical stability and electrical reliability even in vacuum systems or cryogenic settings, making it a favored choice for high-frequency electronics and microwave transmission lines.
We provide C10100 copper tubes specifically designed for plumbing and HVAC applications, ideal for pressure-rated systems that require excellent corrosion resistance and thermal efficiency. C10100 boasts outstanding brazing and soldering properties, making it an ideal choice for clean gas lines, laboratory setups, and sterile conditions.
