C10100 Copper Square Bar Products
Description
Oxygen-free, high-conductivity copper, C10100 (electronic grade) is undoubtedly the purest copper commercially available and possess a unique set of properties. For example, it's freedom from oxygen, as the name implies, gives it immunity to hydrogen embrittlement when exposed to elevated temperatures under reducing conditions.
Typical Uses
Coaxial cables, computer hook-up wire, heat sinks for diodes, rectifiers,and other components, lead wire for circuit breakers and modules, microwave equipment, radar components, solderless connectors and wave guides.
