Dumet wire using Fe/Ni alloy wire as the core material which has the most similar expansion coefficient with that of glass, and clad copper later which has superior heat and electrical conductivity. After further special surface treatment, the copper clad Fe/Ni is covered by a Cu2O film which provides the wire with good sealing ability with glass.
Dumet Wire Applications:
1. Lead-in wires for bulbs, fluorescent lamps, energy saving lamps, Christmas lamps and auto lamps.
2. Conductors for components such as rectifier diodes, surge suppressor and temperature sensors.
