Copper C12200 is an alloy of copper and other metals, such as zinc and tin. This combination gives it excellent machinability, strength, and corrosion resistance. It is commonly used in plumbing systems, air conditioning systems, electrical wiring systems, and architectural applications such as roofing and cladding. Copper C12200 is also known for its superior formability which makes it ideal for creating intricate shapes and designs. With these properties, Copper C12200 is the perfect choice for projects that require long-lasting durability and performance. Whether you're looking to upgrade existing installations or starting a new project from scratch, GNEE's Copper C12200 has everything you need to get the job done right.
Copper C12200, also known as Phosphorus-Deoxidized Copper, is an alloy containing copper and a small amount of phosphorus that offers good electrical conductivity and weldability. It is particularly suitable for applications such as plumbing, HVAC, and general engineering due to its superior resistance to corrosion.

FAQ
Q1: What is the difference between Copper C12200 and Copper C11000 pipes?
A: Copper C12200 contains 0.015-0.04% phosphorus for deoxidization, making it more weldable and corrosion resistant. Copper C11000 (electrolytic tough pitch) has higher electrical conductivity but is not suitable for welding in oxidizing atmospheres.
Q2: Can Copper C12200 seamless pipes be welded without special precautions?
A: Yes, Copper C12200 seamless pipes are phosphorus-deoxidized, which makes them resistant to hydrogen embrittlement and suitable for gas tungsten arc welding (GTAW/TIG) without special precautions.
Q3: Is Copper C12200 the same as oxygen-free copper (OFC)?
A: No. Copper C12200 is phosphorus-deoxidized copper. True oxygen-free copper grades are C10100 and C10200. C12200 has higher phosphorus content and lower conductivity than OFC.
Q4: What is the electrical conductivity of Copper C12200 hard drawn pipes compared to C10200?
A: Copper C12200 hard drawn pipes have approximately 85% IACS conductivity, while C10200 oxygen-free copper has 100% IACS conductivity. C12200 trades some conductivity for better weldability.
Q5: Can Copper C12200 light annealed pipes be used for natural gas lines?
A: Yes, Copper C12200 light annealed pipes are approved for natural gas distribution in many codes (such as NFPA 54), provided local regulations permit copper for gas service.
Q6: What is the maximum working pressure for Copper C12200 seamless tubes at 200°F?
A: For Copper C12200 seamless tubes with 1/2 inch OD and 0.032 inch wall thickness, maximum working pressure at 200°F is approximately 700 psi. Pressure rating varies significantly with diameter and wall thickness.
Q7: Are Copper C12200 rectangular pipes suitable for heat exchanger applications?
A: Yes, Copper C12200 rectangular pipes are used in heat exchangers due to their good thermal conductivity (approx. 200 W/m·K) and corrosion resistance to water and many fluids.
Q8: Does Copper C12200 full annealed pipes require post-weld heat treatment?
A: No, Copper C12200 full annealed pipes typically do not require post-weld heat treatment for most applications, as the material remains ductile after welding.
Q9: What standards cover Copper C12200 seamless pipes for water service?
A: ASTM B88 (seamless copper water tube) and ASTM B75 (seamless copper tube for general engineering) both cover Copper C12200 seamless pipes for water service.
Q10: Can Copper C12200 hard drawn pipes be bent without annealing?
A: Copper C12200 hard drawn pipes have limited ductility. Bending without annealing may cause cracking. For tight bends, use Copper C12200 light annealed or full annealed pipes instead.
Q11: What is the corrosion resistance of Copper C12200 bright pipes against acidic water?
A: Copper C12200 bright pipes have good resistance to neutral and mildly acidic water (pH > 6), but prolonged exposure to water below pH 5 will accelerate corrosion.
Q12: Are Copper C12200 seamless tubes compatible with aluminum fittings in HVAC systems?
A: Direct contact between Copper C12200 seamless tubes and aluminum fittings should be avoided in HVAC systems due to galvanic corrosion risk. Use dielectric unions or brass/bronze fittings instead.
