Product Description

Dumet Wire 0.35mm Red Color Used as Sealing Material For All Kinds of Light Bulb

 


Product introduction:
The iron nickel alloy wire whose expansion coefficient is close to the glass's is used as the core material, and the outer layer is covered with a copper layer with good heat and electrical conductivity. The surface is reprocessed to form a copper oxide film / barrel to increase the good sealing between the surface of the copper layer and the glass.

Product application:

Bulb, fluorescent lamp, energy saving lamp, Christmas lamp, automobile lamp and other bulb guide wire related materials
conductor materials for rectifier diodes, surge arresters, temperature sensing control and other components.

Tankii 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.
