C12100 copper tube is manufactured from phosphorus-deoxidized copper with low residual phosphorus content. It offers good electrical and thermal conductivity, ductility, and resistance to hydrogen embrittlement during suitable high-temperature joining operations. Compared with oxygen-bearing C11000 copper, C12100 is better suited to fabrication processes involving reducing atmospheres.
Seamless C12100 copper tubing may be specified under ASTM B75, subject to the required dimensions and temper. Annealed tubes provide greater flexibility for bending and forming, while drawn tempers offer higher strength and dimensional stability. Outside diameter, wall thickness, and dimensional tolerances should be defined before production.
Typical applications include electrical components, industrial heat transfer assemblies, and fabricated copper tube parts. Sky Steel Group offers C12100 copper tubing for OEM manufacturing and bulk procurement, with available sizes and processing options confirmed during quotation.
Product Features
- Low-Phosphorus Deoxidized Copper – UNS C12100 contains a controlled, low residual phosphorus level, providing a balance of electrical conductivity, thermal performance, and fabrication properties.
- Good Electrical Conductivity – Lower residual phosphorus content generally provides higher electrical conductivity than C12200 copper, making C12100 suitable for selected electrical components and conductive assemblies.
- High Thermal Conductivity – C12100 transfers heat efficiently and is suitable for selected industrial heat transfer components where both thermal performance and fabrication characteristics are important.
- Resistance to Hydrogen Embrittlement – Its deoxidized structure reduces the risk of hydrogen embrittlement during suitable high-temperature joining operations, offering an advantage over oxygen-bearing C11000 copper.
- Annealed & Drawn Tempers – Annealed tubes provide greater ductility for bending and forming, while drawn tempers offer increased strength and dimensional stability for fabricated components.
- Seamless Tube Manufacturing – C12100 copper tubes can be specified for applicable seamless tubing requirements under ASTM B75, with outside diameter, wall thickness, temper, and tolerances confirmed for each order.

Applications
1. Electrical Equipment Components
C12100 copper tubes are used to manufacture selected conductive connectors, tubular sleeves, and electrical equipment components. Their low residual phosphorus content provides higher electrical conductivity than C12200 while retaining the processing advantages of deoxidized copper. Material temper, tube dimensions, and connection methods are selected according to electrical and mechanical requirements.
2. Industrial Heat Transfer Equipment
C12100 copper tubes are used in selected industrial heat exchangers, thermal management assemblies, and heat transfer equipment. Their thermal conductivity supports efficient heat transfer, while the deoxidized copper structure is advantageous for certain high-temperature joining operations. Tube dimensions, wall thickness, and operating conditions must be considered when specifying materials for heat transfer systems.
3. Brazed Copper Tube Assemblies
C12100 copper tubing is suitable for selected brazed tube connections, fabricated piping components, and industrial copper assemblies. Its low-oxygen composition reduces susceptibility to hydrogen embrittlement compared with oxygen-bearing C11000 copper. Brazing procedures, filler metals, and joining temperatures should be selected according to the component design and operating environment.
4. Precision Copper Tube Fabrication
C12100 copper tubes can be processed into bent tubing, tubular connectors, and custom industrial components. Annealed material offers greater ductility for bending and forming, while drawn tempers provide higher strength and dimensional stability. Cutting, bending, and end preparation can be specified according to engineering drawings, dimensional tolerances, and production requirements.
Frequently Asked Questions
1. What is the difference between C12100 and C12200 copper tubes?
Both are phosphorus-deoxidized copper grades, but C12100 contains less residual phosphorus than C12200. This gives C12100 higher electrical and thermal conductivity, making it useful for selected electrical and heat transfer components. C12200 is more commonly specified for plumbing, refrigeration, and general-purpose copper tubing.
2. How does C12100 copper differ from C11000 copper?
C11000 is electrolytic tough pitch copper with approximately 100% IACS conductivity in the annealed condition. C12100 is low-phosphorus deoxidized copper with somewhat lower conductivity but better resistance to hydrogen embrittlement during suitable high-temperature processing. C11000 is often preferred for electrical conductors, while C12100 offers advantages for certain joined assemblies.
3. Which ASTM standard applies to C12100 copper tubes?
ASTM B75 covers seamless copper tubes and may be specified for C12100 tubing where the grade and product requirements fall within the applicable standard. Buyers should confirm the required standard edition, outside diameter, wall thickness, temper, and dimensional tolerances with the supplier before placing an order.
4. Can C12100 copper tubes be brazed or welded?
C12100 is suitable for selected brazing and welding operations because its deoxidized composition reduces the risk of hydrogen embrittlement associated with oxygen-bearing copper. Joint quality still depends on the filler metal, heating method, shielding atmosphere, and component geometry. Welding and brazing procedures should be qualified for the intended application.
5. What is the difference between annealed and drawn C12100 copper tubes?
Annealed C12100 tubing offers greater ductility and is suitable for bending, flaring, and forming operations. Drawn tempers provide higher tensile strength and improved dimensional stability for straight tubes and machined components. The required temper should be selected according to fabrication methods, mechanical loading, and dimensional requirements.
6. What specifications should buyers provide when ordering C12100 copper tubes?
Buyers should provide the material grade, applicable ASTM standard, outside diameter, wall thickness, length, temper, and required quantity. For electrical or heat transfer applications, conductivity, operating conditions, and dimensional tolerances may also need confirmation. Material test reports and additional inspection requirements should be agreed upon before production.
