0.12mm 80/20 Waea Nichrome mo nga Umu Ahumahi
Ko nga koranu Nickel Chrome (NiCr) he rauemi aukati teitei e whakamahia ana i roto i nga tono me te teitei o te pāmahana whakahaere ki te 1,250°C (2,280°F).
Ko enei koranu Austenitic e mohiotia ana mo to ratou kaha miihini teitei ake i te pāmahana ka whakaritea ki nga koranu FeCrAl tae atu ki te kaha o te ngokingoki. Ko nga koranu Nickel Chrome ka kaha ake te ngongo ina whakaritea ki nga koranu FeCrAl i muri i nga wa roa i te pāmahana. Ka hangaia he Chromium Oxide pouri (Cr2O3) i nga wera teitei e kaha ana ki te pakaru, ki te pahekeheke ranei, ka pa mai pea te poke i runga i te tono. Ko tenei waikura karekau he waahi whakamaarama hiko penei i te Aluminum Oxide (Al2O3) o nga koranu FeCrA. Ko nga koranu Nickel Chrome e whakaatu ana i te pai o te waikura haunga ki nga taiao kei reira te whanariki.
