TOSHIBA dumet wires are widely used for soft glass-to-metal sealing.
The history of dumet wire development is all about the history of lamp development. TOSHIBA is the first company in Japan to undertake the experimental production of dumet wires in 1915, and started full-scale production in 1917.
Since then, TOSHIBA has been manufacturing high-quality dumet wires as a leading manufacturer in Japan for a wide range of applications such as light bulbs, electron tubes, discharge lamps and semiconductors.
