C10100 OFE Copper Tube

Gnee Steel (Tianjin) Co., Ltd. is one of the most professional manufacturers and suppliers of c10100 ofe copper tube in China, also supports customized service. Welcome to buy discount c10100 ofe copper tube for sale here from our factory. Quality products and reasonable price are available.

When transmitting high-frequency signals, cooling high-power electronics, or building ultra-high vacuum (UHV) systems, the integrity of your copper tubing is critical. Our C10100 OFE (Oxygen-Free Electronic) copper tubes are exclusively seamless, extruded, and precision cold-drawn.

With a guaranteed minimum purity of 99.99% Cu and oxygen levels strictly capped at <5 ppm, our OFE copper tubing offers absolute immunity to hydrogen embrittlement during high-temperature brazing and glass-to-metal sealing.

100% Seamless Construction: No weld seams means zero risk of outgassing or microscopic leaks in UHV environments.

Precision Concentricity: Highly uniform wall thickness ensures consistent flow rates and reliable CNC bending without wrinkling.

Superior Internal Finish: We strictly control internal surface roughness (Ra) to minimize signal loss in RF/microwave applications.

Contamination-Free: All tubes undergo rigorous ultrasonic degreasing and are supplied with capped ends to prevent internal contamination during transit.

1. Delivery Forms (Packaging Shapes):

Straight Lengths (Rigid Pipes): Ideal for UHV beamlines, rigid structural feeds, and CNC machining. Supplied in standard lengths up to 6 meters (20 feet) or custom precision-cut blanks.

Pancake Coils & LWC (Level Wound Coils): Essential for continuous cryogenic cooling systems (like MRI scanners) and heat exchangers where brazed joints must be minimized to prevent leaks. Available in ultra-long continuous lengths.

Capillary Tubes: Extremely small O.D. and thin-wall tubes supplied in coils for precision instrumentation and medical devices.

2. Available Tempers (Hardness States):

Soft Annealed (O60 / O50): Highly ductile. This is the mandatory temper if your tubes require complex CNC mandrel bending, flaring, or spinning without cracking.

Half Hard / Light Drawn (H55): Provides a perfect balance. It retains enough ductility for moderate bending while offering enough rigidity to span distances without sagging.

Hard Drawn (H80): Maximum stiffness and tensile strength. Best suited for straight, rigid UHV pipelines or thick-walled pipes that will undergo aggressive CNC turning and threading (ensures excellent chip breaking).

C10100 tubes are strictly specified for industries where standard deoxidized copper (like C12200) fails due to outgassing or lower conductivity:

UHV Beamlines & Feedthroughs: The absolute absence of volatile impurities and seamless structure make our tubes the standard for particle accelerators and vacuum feedthroughs.

RF & Microwave Waveguides (Square/Rectangular): High IACS conductivity combined with a mirror-like internal surface finish ensures minimal signal attenuation in high-frequency radar and communications.

Cryogenics & MRI Medical Equipment: The exceptional thermal conductivity of C10100 at extreme sub-zero temperatures makes our tubes ideal for liquid helium cooling lines in MRI scanners.

Don't spend time and resources processing raw tubes in-house. We deliver ready-to-install tubular components:

Precision CNC Bending: Mandrel bending services to achieve tight bend radii without tube collapse, wrinkling, or wall thinning.

Precision Cutting & Deburring: Burr-free saw cutting and chamfering for exact lengths, ready for automatic orbital welding.

Flaring & Swaging: End-forming services for creating secure mechanical joints or custom fluid connections.

CNC Turning: Machining the OD/ID of thick-walled pipes to create stepped UHV fittings or custom flanges.

Internal cleanliness is just as important as the material itself in UHV and medical applications.

Ultrasonic Degreasing: All tubes go through a multi-stage ultrasonic cleaning process to remove all drawing oils and residual compounds.

End-Capping: Every single tube is fitted with tight plastic end caps immediately after cleaning to seal the inner diameter from dust and moisture.

Vacuum Packing: Bundles are wrapped in VCI anti-rust film and sealed.

Rigid Wooden Crating: Packed in heavy-duty, fumigated wooden cases to guarantee tubes remain perfectly straight and uncrushed during ocean freight.

We maintain absolute control over the quality of our seamless OFE copper tubes. Our facility utilizes high-tonnage extrusion presses and precision cold-drawing benches (Pilger mills) to achieve exceptional dimensional accuracy and grain structure.

To ensure zero defects for high-vacuum applications, every batch of our C10100 tubing undergoes rigorous Eddy Current Testing (ECT) or Ultrasonic Flaw Detection to identify any microscopic internal cracks or voids. Combined with our in-house spectrometer (OES) purity testing, we guarantee that the tubes you receive are 100% compliant with ASTM F68 standards and ready for critical deployments.
