GNEE provides the form
Products Description
GNEE offers a wide variety of oxygen-free copper tubing designed for industries requiring superior electrical conductivity, thermal efficiency, and corrosion resistance. C10100 copper tubing is widely used in power systems, heat exchangers, refrigeration units, transformers, aerospace, and industrial machinery. We manufacture these tubing to stringent industry standards, ensuring durability and high performance in demanding applications.
C10100 copper, also known as OFHC (Oxygen-Free High Conductivity Copper), is a high-purity copper alloy with a composition of 99.99% and an oxygen content of less than 0.0005%. This extremely low oxygen content enhances its resistance to hydrogen damage, making it a popular choice for vacuum environments, refrigeration systems, and high-frequency electrical applications. Its excellent thermal conductivity of approximately 391 W/m·K makes it ideal for heat exchangers and industrial cooling systems.
At GNEE, we prioritize the careful packaging and fast delivery of our C10100 copper tubing. Our copper tubing is meticulously packaged in wooden crates and features moisture-proof packaging and a protective coating to prevent oxidation and mechanical damage during transportation. We provide high-performance copper piping solutions to a wide range of industries worldwide, with fast domestic and international shipping services.
We offer a wide variety of C10100 copper tubes, including seamless, welded, drawn, and custom-sized tubes for a variety of industrial applications. We produce these tubes in accordance with ASTM B68, ASTM B75, ASTM B88, and ASTM B280 standards, ensuring superior mechanical strength, consistent grain structure, and a smooth surface finish. Our high-purity copper tubes are available in hard, semi-hard, and soft tempers, with diameters ranging from 6 mm to 300 mm and wall thicknesses suitable for both low- and high-pressure applications.
Our oxygen-free copper C10100 tubes are widely used in busbars, high-voltage connectors, semiconductor processing, and industrial furnaces. Seamless copper tubes ensure reliable, leak-free operation in HVAC systems, refrigeration units, and natural gas pipelines, while large-diameter copper tubes are widely used in power generation and aerospace. Their excellent corrosion resistance makes them ideal for marine and chemical processing applications operating in high-risk environments such as moisture, acids, and harsh chemicals.
