Thermal conductivity at 20°C
C110 Copper – 391 W/mK (This copper is also designated “Electrolytic tough pitch Copper, UNS C11000”)
Thermal conductivity at 20°C
C101 Copper – 388 W/mK (This copper is also designated “Oxygen-free electronic Copper, UNS C10100”)
Funny thing about all this is that the old 3 digit designation for the UK is C110 for that which is UNS C11000 now. This copper actually has a greater thermal conductivity than C101 (UK) which is now UNS C10100.
