C12200 copper pipe is a high-purity oxygen-free copper material with good corrosion resistance and easy processing. C122 is commercially pure copper that has been phosphorus deoxidized, leaving a relatively high residual phosphorus content. Copper Alloy 122 is less susceptible to hydrogen embrittlement but has relatively low electrical conductivity due to the phosphorus content.

Composition: Copper C11000 pipes are a high-purity copper alloy with a minimum copper content of 99.90%, while Copper C12200 pipes are a brass alloy containing copper and zinc with a copper content of approximately 99.9%.

Strength: Copper C12200 pipes have higher tensile strength and yield strength compared to Copper C11000 pipes. This makes them more suitable for applications requiring higher mechanical strength, such as fasteners and connectors.

Corrosion Resistance: Both Copper C11000 and C12200 pipes are highly resistant to corrosion. However, Copper C11000 pipes offer better resistance to corrosion in seawater and marine environments due to their high copper content.

Electrical Conductivity: Copper C11000 pipes have the highest electrical conductivity of all copper alloys, making them an excellent choice for electrical applications that require high conductivity.

Thermal Conductivity: Both Copper C11000 and C12200 pipes have excellent thermal conductivity. However, Copper C11000 pipes have slightly higher thermal conductivity than C12200 pipes.

Fabrication: Both Copper C11000 and C12200 pipes are easy to machine and fabricate. However, Copper C12200 pipes are more easily formed due to their higher zinc content.
