What Is C10200
C10200 is a high-purity oxygen-free copper widely used in electrical, electronic, and communication fields for its excellent electrical conductivity, thermal conductivity, corrosion resistance, and good processing performance. It is the standard oxygen-free grade specified for applications requiring maximum conductivity and freedom from oxygen-related defects.
Chemical Composition
The copper content is extremely high, usually above 99.95 percent, ensuring the high purity of the material. Impurity elements such as oxygen, phosphorus, iron, nickel, lead, tin, sulfur, and zinc are strictly controlled, with the oxygen content controlled within 10 ppm. The absence of oxygen eliminates the risk of hydrogen embrittlement during high-temperature processing.
Physical Properties
C10200 has very high electrical conductivity, up to 100 percent IACS or more, making it an ideal conductive material. Thermal conductivity is excellent, suitable for applications requiring efficient heat dissipation. Density is about 8.9 g per cubic centimeter.
Mechanical Properties
Depending on the condition, the tensile strength ranges from 275 to 740 MPa, with cold-worked tempers providing the higher values. Elongation is more than 35 percent in annealed material, and hardness is moderate, making the alloy easy to process and form.
Applications
C10200 is used for electrical conductors and busbars, magnet wire, heat exchangers, waveguides, vacuum components, and cryogenic equipment. Its combination of conductivity, formability, and purity also serves semiconductor equipment and high-end audio cables.
