Hai-Nicr70 Waea Papatahi mo te Taapiri Taapiri Taapiri Aatete Parai
Hai-Nicr70 Waea PapatahimoNga Roopu Takirua Perehi parei
Ni70Cr30he koranu nickel-chromium (NiCr alloy) e tohuhia ana e te parenga teitei, te pai o te waiora me te tino pai o te ahua. He pai mo te whakamahi i te pāmahana tae atu ki te 1250°C, me te pupuri i te oranga ratonga pai ake i whakaritea ki te Iron chromium alumium alloys.
Nga tono angamaheni moNi70Cr30he huānga whakawera hiko i roto i nga taputapu whare, oumu ahumahi me te parenga (nga parenga waea, nga parenga kiriata whakarewa), rino papatahi, mihini rino, whakamahana wai, mate hangai kirihou, rino whakapiri, huānga ngongo ngongo me nga huānga kariri.
