1. Basic concept and classification
C10800 oxygen-free copper is a high-purity copper material, in line with the American ASTM B152 standard C10800 grade requirements. It is known for its very low oxygen content (usually ≤ 0.001%) and excellent electrical and thermal conductivity, widely used in electronics, electrical, communications, high vacuum equipment and other fields, especially in the purity of the material and the performance of the occasions require very high.
2. Chemical composition
The chemical composition of C10800 oxygen-free copper is in accordance with ASTM B152 standard, as follows:
Copper (Cu): ≥99.99%
Oxygen (O): ≤ 0.001% (10 ppm)
Other impurities: ≤0.001% (such as silver, iron, sulfur, phosphorus, etc.)
C10800 oxygen-free copper is extremely pure and low in oxygen content, which is the key characteristic that distinguishes it from ordinary copper.
