fernico मीनिंग इन हिंदी

उदाहरण वाक्य

1. Fernico is used at high temperatures and is identical to Kovar.
2. Fernico II is used at cryogenic temperatures in the range.
3. Other metals, including copper, molybdenum, nickel, and steel can be spot-welded to the FerNiCo alloys forming low resistance electrical connections.
4. Metal alloys ( such as Cunife and Fernico ) and glasses had been developed for light bulbs that expanded and contracted in similar amounts, as temperature changed.
5. Electrolytic effects from the differing metals used for the miniature tube pins ( usually Cunife or Fernico ) and the tube base could cause intermittent contact due to local corrosion, especially in relatively low current tubes such as were used in battery-operated radio sets.
6. FerNiCo I has the same linear coefficient of expansion as certain types of borosilicate ( " hard " glass ), ( c6.5 ?10  " 6 �K  " 1, thus serving as an ideal material for the lead-out wires or other seal structures in light bulbs and thermionic valves.
7. "' Kovar "'( trademark of CRS Holdings, inc ., Delaware ) is a nickel cobalt ferrous alloy compositionally identical to Fernico 1, designed to have substantially the same thermal expansion characteristics as borosilicate glass ( ~ 5 ?10  " 6 / K between 30 and 200 �C, to ~ 10 ?10  " 6 / K at 800 �C ) in order to allow a tight mechanical joint between the two materials over a range of temperatures.
