Products Description
The high purity of C10100 copper alloy is one of its most significant characteristics. High purity means extremely low impurity content, ensuring the stability and consistency of its physical properties. This high purity makes C10100 copper alloy excellent in terms of electrical conductivity, thermal conductivity, corrosion resistance, and mechanical strength. Particularly in terms of electrical conductivity, C10100 copper alloy has a conductivity close to that of pure copper and far exceeds that of other types of copper alloys, giving it an unparalleled advantage in applications requiring efficient current transmission. Furthermore, C10100 copper alloy also possesses good machinability and plasticity. It can be processed into parts of various shapes and sizes through various forming processes, such as casting, forging, rolling, and drawing. This excellent machinability not only improves production efficiency but also reduces manufacturing costs, making C10100 copper alloy more competitive in electronics manufacturing.
Key Characteristics
High Conductivity: Possesses an electrical conductivity of up to 101% IACS (International Annealed Copper Standard), making it ideal for power transmission and precision electronic applications.
High Thermal Conductivity: Excellent thermal conductivity, making it highly suitable for heat exchangers, heating coils, and cooling systems.
Excellent Ductility and Formability: Easily undergoes cold working operations such as bending, stamping, and drawing.
Resistance to Hydrogen Embrittlement: The absence of oxygen prevents embrittlement when exposed to reducing atmospheres at high temperatures, a key distinction from oxygen-bearing coppers.
Excellent Weldability and Brazeability: A clean, pure surface ensures strong, reliable joints.

Comparison with Other Copper Tubes
C10200 (Oxygen-Free Copper): Slightly lower copper content (99.95%), performance is very close to C10100, a common and economical alternative.
C11000 (Electrolytic Tough Pitch Copper): Contains 0.02% to 0.05% oxygen. Excellent conductivity (~100% IACS) but susceptible to hydrogen embrittlement in high-temperature reducing atmospheres.
