The Standard for Power Devices

TANAKA Denshi Kogyo offers high-purity aluminum (Al) and copper (Cu) bonding wires and ribbons with excellent surface properties of automotive grade. As aluminum has excellent corrosion resistance , it is often used in power device applications that drive high currents under harsh environments. We also have wires for power devices that use copper, which has even better electrical conductivity.
