C102/C110 Copper Conductor Wire
Download PDFCopper is the “standard” metal used for electrical conductors. Copper has extremely high electrical conductivity, surpassed only by pure silver and it has excellent tensile, solderability and corrosion characteristics.
C102 is an oxygen free (OF) copper that has better drawing and resistance to hydrogen embrittlement than C110 (ETP). OF copper contains less dissolved oxygen than ETP, which gives OF its performance advantage. In most applications, ETP is an acceptable conductor material and is more economical than OF copper.
Both OF and ETP copper conductors are available bare or plated with silver, nickel or tin.
