Nickel Chromium NiCr Alloy
Ko nga taonga Nickel-chromium e whakamahia nuitia ana i roto i nga oumu hiko ahumahi, nga taputapu whare, nga taputapu mamao-infrared me etahi atu taputapu na te kaha o te kaha o te wera nui me te kirihou kaha. Nickel-chromium me te rino, te konumohe, te silicon, te waro, te whanariki me etahi atu mea ka taea te hanga ki te waea whakarewa nickel-chromium, he nui te parenga me te wera o te wera me te mea te huānga whakawera hiko o te oumu hiko, te rino hiko, te rino hiko me etahi atu hua.
I tua atu, ko te waea NiCr te nuinga o te wa e whakamahia ana i roto i te porowhita o te rheostat retireti ki te tiaki i te ara iahiko me te huri i te naianei i roto i te ara iahiko ma te huri i te parenga o te wahanga ara iahiko uru, na reira ka huri te ngaohiko puta noa i te kaikawe (taputapu hiko) hono i roto i te raupapa me it, Kei te whakamahia nuitia i roto i te maha o nga taputapu whare.
NiCr Alloy Series
Ko te riu Ni90Cr10 he momo hua koranu nickel-chromium, he pai mo nga tono pāmahana tae atu ki te 1250°C. Ko nga ihirangi Chromium e whakarato ana i te waa ora tino pai, ka whakamahia hei huānga whakawera vape.
Ko te Ni90Cr10 e tohuhia ana e te parenga teitei, te pai o te waikura, te pai o te whakaheke i muri i te whakamahinga me te pai o te weldability. Ko te NiCr Alloy he rauemi pai mo te ahumahi whakawera.
