Product Description

 Copper-Clad Ni-Fe Wire Borated Dumet wire with  0.3mm 0.35mm 

Dumet wire Chemical composition :Ni 41~43%, Fe Balance

Dumet wire consists of a nickel-iron core in an oxygen-free-high-conductivity copper sheath.

Dumet  is a glass-to-metal sealing alloy. It is a bimetal made of a nickel-iron core encased in an oxygen-free-high- conductivity (OFHC) copper sheath.
Dumet wire is used as a glass-to-metal seal in manufacturing of lamps, diodes, and capacitor slug leads.
It is used as the pinch-lead in Lead-in-Wires that are used in incandescent, fluorescent tube, automotive, halogens, HID, decorative, and other special purpose lamps. 

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.
