Copper Round Tube 101

Copper Round Tube 101

Copper 101 round tube (oxygen free high conductivity copper, OFHC) is a high purity copper alloy containing a minimum of 99.99% copper with no oxygen content. This composition delivers exceptional electrical and thermal conductivity along with resistance to hydrogen embrittlement at elevated temperatures. Compared to standard copper tubing grades, 101 provides superior performance in high temperature and high conductivity environments. It is easily formed, welded, and brazed, making it ideal for precision electrical and scientific applications.


Applications: Electrical conduits, high conductivity systems, vacuum components, particle accelerators, precision tubing applications.


Supply Options: Standard Lengths | Custom Cut
