High thermal and electrical conductivity and high
ductility combined with low volatility makes this material indispensable in
the electronics industry.
Applications
Some typical uses for Copper Alloy 10100 in the electrical
and electronic industries are bus bars, bus conductors, wave guides, hollow
conductors, lead-in wires and anodes for vacuum tubes, glass to metal seals
and others.
