Copper C101
Material Notes: C101, or Copper with Oxygen Free Electronic Copper, remains one of the highest grades of copper for use in technical applications as its production is done free of oxygen and contaminants. Its purity reaches as high as 99.99% which yields remarkable conductivity with a value of 101% IACS.
Applications: Copper C101 is a high-purity copper that is highly sought after due to its superb heat and electricity conduction. It is widely utilized in electrical sectors and inother fields that demand precision. C101 is perfectly suited for connectors, wiring, transformers, motors, and even heat exchangers.
