C10100, also knowns as Cu-OFE, is the premium pure copper grade, CW009A is the EN numeric designation while C10100 is the UNS number. It has a very fine-grained structure and consists of a pure automotive crystal lattice. This copper grade is high-purity with at least 99.99% of copper, and its oxygen level is below 5ppm, and the absence of oxidic inclusions result in a very high electrical conductivity. That's why It can reach extreme electrical conductivity of 101 % IACS. Furthermore, the material shows no susceptibility to hydrogen embrittlement. It has very good hot and cold formability and good corrosion resistance to atmosphere and water. It is practically insensitive to stress corrosion cracking.

Application
Cu-OFE is a very high purity certified grade of oxygen free copper for electronic type applications. The material is
manufactured from pure cathode copper and poured in a protective gas atmosphere and therefore its oxygen content is restricted to minimize hydrogen embrittlement risk. It has wide commercial applications including:
√ Circuit
√ Breakers
√ Electrical instruments
√ Vacuum capacitors
√ Magnetrons
√ Electrical components at cryogenic temperatures
√ Anodes
√ Semi-conductors
√ Transformers
√ Waveguides
√ Hollow conductors
√ High vacuum industry
√ Automotive rectifier
√ Vacuum components such as vacuum interrupters, X-ray tubes and radio transmitters
Test Requirements
According to EN13604, there are number of mandatory tests required for Cu-OFE (CW009A) as it is widely used for
electronic, semiconductor and vacuum applications. Fabmann perform strict quality control measures as follows:
√ Chemical analysis
√ Mechanical properties
√ Electrical properties
√ Hydrogen embrittlement
√ Scale adhesion
√ Grain size (smaller than 0.050mm)
√ Tolerances of dimensions
√ Surface condition (clean, sound and free from injurious defects)
If you have other chemical requirement such as hydrogen content, Fabmann can also assist you the full analysis of each required element. Fabmann supply full range of top notch Cu-OFE products, and we are particularly committed to providing custom solution for your project needs.
