FeNi Nickel Birta Alloy Precision 0.5mm Invar 36 Silig Lagu Xidho Qalabka Saxda ah
FeNi Nickel Birta birta saxda ah 0.5mmInvar 36 WireQalabka saxda ah ee lagu xidho
INVAR 36waa bir-nikkel, alloy fidinta hoose oo ka kooban 36% nikkel.Waxay ilaalisaa cabbirro joogto ah oo ku dhow inta u dhexeysa heerkulka caadiga ah ee jawiga, waxayna leedahay isku-dhafka hoose ee ballaarinta heerkulka cryogenic ilaa 500 ° F. Daawadu waxay sidoo kale haysaa xoog wanaagsan iyo adkaanshaha heerkulka cryogenic.
INVAR 36waxay noqon kartaa kulayl iyo qabow la sameeyay oo la mashiino iyadoo la isticmaalayo habab la mid ah
austenitic ahama.INVAR 36 waa alxanka iyadoo la isticmaalayo Filler Metal CF36 taas oo ah
Waxaa lagu heli karaa silig qaawan oo loogu talagalay habka GTAW iyo GMAW labadaba.
