What is C10100 Copper?
C10100, also known as Oxygen-Free Electronic (OFE) Copper, is a pure copper grade with a minimum of 99.99% Cu content. It is characterized by having virtually no oxygen (typically < 0.0005%) and extremely high electrical conductivity.
What is the key difference between C10100, C10200 (OF), and C11000 (ETP)?
The primary difference is oxygen content and purity.
C10100 (OFE): 99.99% Cu, oxygen-free. Highest conductivity and formability.
C10200 (OF): 99.95% Cu, oxygen-free. Slightly lower purity than OFE.
C11000 (ETP): 99.90% Cu, contains oxygen. Standard for general electrical applications but less suitable for high-temperature, reducing atmospheres.
What is the electrical conductivity of C10100?
C10100 has the highest electrical conductivity of all coppers, rated at 101% IACS (International Annealed Copper Standard). This is the benchmark for 100% conductivity.
What is the thermal conductivity of C10100?
It has excellent thermal conductivity, approximately 391 W/m·K at 20°C, making it ideal for heat exchangers and cooling applications.
What are the most common applications for C10100?
Its primary applications include:
High-vacuum electronic tubes (klystrons, magnetrons)
Waveguides
Transistor components
Bus bars and high-current conductors
Superconducting wire stabilizers
Sputtering targets
Glass-to-metal seals
