Waea Nichrome Ni35Cr20, he kaha whakarewa teitei, he rahi 0.4mm, mō te oumu ahumahi.

Whakaahuatanga Poto:

He pai ngā painga o te waea koranu nikara-konukōmiuma, nikara, ferrochrome, ātete ki te waikura i te pāmahana teitei, he kaha teitei, kāore e whakangawari, ā, he maha ngā painga. He iti noa te roa o te whakamahinga o te momo kotahi, ā, he iti noa te whakaroa pumau, nō reira koinei te kōwhiringa pai rawa atu hei hanga i ngā wāhanga hiko kounga teitei.

    Ngā Tohu Hua

    He whānuitia te whakamahinga o ngā koranu ātete hiko i roto i ngā whakamahana hiko, inā koa ko te NiCr. Ko te Nichrome he koranu nikara me te chromium e whakamahia whānuitia ana i roto i te hanga waea ātete nā te mea he teitei te ātete me ōna āhuatanga ārai-waikura pumau i ngā pāmahana tae atu ki te 1250°C, koia te take he pai ngā waea ātete mō te mahi i roto i ngā taiao tino kino e pāngia ana e te pēhanga me te wera. Kua hangaia e Vladimir Plant of Precision Alloys ngā koranu ātete me ngā koranu whakamahana mai i tōna turanga. Ko tā mātou kaha ko te hanga waea, rīpene, rīpene me te pepa konutea, tae atu ki ngā koranu NiCr me ngā koranu Fe-Cr-Al.
