Dumet wire (13)
Product name: Dumet wire
Dumet wire consists of a nickel-iron core in an oxygen-free-high-conductivity copper sheath. It is available in various surface finishes: Electrically oxidised, borax coated, nickel plated, bare (uncoated).
Borated surface finish Dumet is used in Lead-in-wires for lamps. Dumet forms a glass-to-metal seal while manufacturing these lamps. The oxidised Dumet is used in Lead-in-wires, diodes and capacitor slug leads application.
