Oxygen –Free, High Conductivity Copper (OFE, CW009A, C101) –alloy (99.99 % minimum Cu) offers
the advantages of both Electrolytic Tough Pitch Copper (ETP, CW004A, C110)-alloy and Phosphor Deoxidized Copper (DHP, CW024A, C122) -alloy. The high purity and absence of deoxidisers
accounts for electrical conductivity of 101 % IACS as well as no susceptibility for hydrogen embrittlement. Due to the absence of oxides in the structure, OFE-OK is capable of withstanding critical electrical, electronic and communication applications
Properties:
• Highest possible electrical conductivity min. 101 % IACS
• Highest possible thermal conductivity
