Products Description
C10100 Oxygen Free High Conductivity Copper is produced by the direct conversion of selected refined cathodes and castings under carefully controlled conditions to prevent any contamination of the pure oxygen-free metal during processing. The method of producing O.F.H.C. copper insures an extra high grade of metal with a copper content of 99.99%. With such small content of extraneous elements, the inherent properties of elemental copper are brought forth to a high degree. Among such characteristics are high ductility, high electrical and thermal conductivity, high impact strength, good creep resistance, ease of weldability and low volatility under high vacuum.
Physical and Mechanical Properties
1. Electrical and Thermal Conductivity: C10100 exhibits electrical conductivity exceeding 100% IACS (International Standard for Annealed Copper) and a thermal conductivity as high as 398 W/(m·K), making it an ideal material for power transmission and heat dissipation devices.
2. Mechanical Properties: In the annealed state, the tensile strength is approximately 200-250 MPa, and the elongation can reach over 45%, making it easy to process into complex shapes. After cold working, the strength can be increased to over 300 MPa, but the ductility will decrease.
3. Corrosion Resistance: It has good oxidation resistance in dry environments, but surface protection is required in humid or sulfur-containing environments.
Ductility and Formability
C10100 oxygen-free copper boasts a soft elongation of ≥45%, an exceptional ductility that allows it to be drawn into ultra-fine wires of 0.003mm, a thickness only 1/20th the diameter of a human hair. Such fine wires have wide applications in microelectronic devices, meeting the high-precision requirements of these devices and enabling the development of microelectronic technology. Its deep drawing limit ratio (LDR) reaches 2.3, meaning it performs exceptionally well in deep drawing, suitable for one-time forming of complex curved parts. When manufacturing precision electronic component housings or complex aerospace parts, C10100 oxygen-free copper can easily handle the task, achieving the desired shape in a single deep drawing process, significantly improving production efficiency and product quality.
