Aisea Inconel Kovar ?

1.Kovar o loʻo i ai le lautele o le faʻaogaina i totonu o mea tau eletise, e pei o vaega uʻamea faʻapipiʻi i teutusi tioata malo.O nei vaega o loʻo faʻaaogaina mo ia masini e pei o le eletise ma le X-ray tubes, ma isi.
2.In le semiconductor alamanuia kovar o loʻo faʻaaogaina i totonu o pusa faʻamaufaʻailogaina mo masini faʻapipiʻi tuʻufaʻatasia ma vavae.
3.Kovar e tuʻuina atu i ituaiga eseese e faʻafaigofie ai le gaosiga lelei o vaega uʻamea eseese.O lo'o iai uiga fa'alauteleina o le vevela e fetaui ma le tioata malo.Fa'aoga mo so'oga fa'alautele fa'afetaui i le va o metala ma tioata po'o sima.
4. Kovar u'amea o se gaogao liusuavai, u'amea-nickel-kobalt, fa'alautelega fa'apalapala maualalo o lo'o fa'atonuina le vaila'au i totonu o tapula'a vaapiapi e fa'amautinoa ai le sa'o lelei o le fa'alauteleina o meatotino.E tele fa'atonuga lelei o lo'o fa'aaogaina i le gaosiga o lenei u'amea e fa'amautinoa ai le tutusa o mea fa'aletino ma fa'ainisinia mo le fa'afaigofieina o ata loloto, fa'ailoga ma masini.

Kovar Alloy Talosaga fanua:

● Kovar alloy ua faʻaaogaina mo le faia o faʻamaufaʻailoga hermetic faʻatasi ai ma tioata Pyrex sili atu ona faigata ma mea sima.
●O lenei u'amea ua maua le tele o le faʻaogaina i le eletise, microwave tubes, transistors ma diodes.I ta'amilosaga fa'atasi, ua fa'aaogaina mo le afifi mafolafola ma le afifi lua-i-laina.
