Abstract:
The dumet wire (or glass sealing copper-coated alloy
wire) is the name of Fe+Ni alloy wire combined with
copper. The wire is fabricated in accordance with the
advanced brushless hot drawing process developed by
the Korea Advanced Institute of Science and Technology
(KA 1ST).
The glass sealing copper-coated alloy wire is a glass
sealing electric conductor which is particularly essential
in the manufacture of electric bulbs. With an increasing
demand for such bulbs in extensive electrification
projects for farm and fishing villages in developing
countries, the production of electric bulbs, one of the
labor-intensive type products, is in the trend of gradually
shifting to these countries from advanced nations.
It is mandatory to domestically produce this glass
sealing copper-coated alloy wire which is a basic material
for manufacturing electric bulbs.
