Tuatahi, he mea nui kia mārama ake tō rāua whanaungatanga:Nichrome(he whakarāpopototanga mō te koranu nikara-konukōmiuma) he kāwai whānui o ngā koranu e hangai ana ki te nikara-konukōmiuma, i te meaNi80he momo nichrome motuhake me te hanganga pumau (80% nickel, 20% chromium). Ko te "rerekētanga" kei roto i te "kāwai whānui vs. momo motuhake"—no te whānau nichrome te Ni80 engari he āhuatanga ahurei nā tōna pumau, e pai ai mō ngā āhuatanga pāmahana teitei motuhake. Kei raro nei he whakataurite taipitopito:
| Āhuatanga | Nichrome (Kāwai Whānui) | Ni80 (Momo Nichrome Motuhake) |
| Whakamāramatanga | He whānau koranu i hangaia i te nikara (50–80%) me te konukōmiuma (10–30%), me ētahi atu tāpiringa (hei tauira, te rino) | He momo nichrome kounga teitei me te hanganga tino pakari: 80% nickel + 20% chromium (kāore he tāpiringa tāpiri) |
| Ngāwari o te Hanga | Ngā ōwehenga nikara-konukōmiuma rerekē (hei tauira, Ni60Cr15, Ni70Cr30) hei whakatutuki i ngā hiahia rerekē | Te ōwehenga nikara-konukōmiuma 80:20 kua pumau (kāore he ngāwari o ngā wāhanga matua) |
| Mahi Matua | Ātete pāmahana teitei (800–1000°C), ātete waikura taketake, me te ātete hiko ka taea te whakarerekē | He ātete pāmahana teitei rawa atu (tae atu ki te 1200°C), he ātete waikura tino pai (he iti te tauine i te 1000°C+), me te ātete hiko pumau (1.1–1.2 Ω/mm²) |
| Ngā tono noa | Ngā āhuatanga whakamahana pāmahana waenga-iti (hei tauira, ngā ngongo whakamahana taputapu whare, ngā whakamahana iti, ngā whakamahana ahumahi iti-mana) | Ngā āhuatanga pāmahana teitei, tono nui (hei tauira, ngā koiri oumu ahumahi, ngā pito wera o te pūreretā 3D, ngā wāhanga tango hukapapa rererangi) |
| Ngā Here | Te pāmahana mōrahi iti iho; ka rerekē te mahi i runga i te ōwehenga motuhake (ka tere te waikura o ētahi momo i ngā pāmahana tiketike) | Te utu nui ake o ngā rauemi mata; he nui rawa te āheinga mō ngā āhuatanga pāmahana iti (kāore i te whai hua te utu) |
1. Hanganga: Pūmau vs. Ngāwari
Mā te nichrome hei wāhanga ka taea te whakarerekē i ngā ōwehenga nickel-chromium hei whakataurite i te utu me te mahi. Hei tauira, ka tāpirihia e te Ni60Cr15 (60% Ni, 15% Cr) te rino hei whakaiti i te utu engari ka whakaiti i te ātete wera. He rerekē, he ōwehenga nickel-chromium 80:20 te Ni80—nā te nui o te nickel i roto i tēnei rauemi te take e pai ake ai i ētahi atu momo nichrome i roto i te ātete waikura me te manawanui pāmahana. Ka piri pūmau tā mātou Ni80 ki te paerewa 80:20, me te tika o te hanganga i roto i te ±0.5% (i whakamatautauria mā te tirotiro mimiti ngota).
2. Mahi: Motuhake vs. Whānui-Whakaaro
Mō ngā hiahia pāmahana teitei (1000–1200°C), kāore he rite o te Ni80. Ka mau tonu te pumau o te hanganga i roto i ngā oumu ahumahi, i ngā pito wera rānei o te pūreretā 3D, ko ētahi atu nichrome (hei tauira, Ni70Cr30) ka tīmata pea te waikura, te whakarerekē rānei i te āhua i runga ake i te 1000°C. Heoi, mō ngā mahi pāmahana waenga-iti (hei tauira, he whakamahana whakamaroke makawe 600°C), kāore e hiahiatia te whakamahi i te Ni80—he pai te mahi a ngā momo nichrome iti te utu. Ka hipokina e tā mātou raina hua te Ni80 (mō ngā āhuatanga tono nui) me ētahi atu nichrome (mō ngā hiahia pāmahana iti, he iti te utu).
3. Taupānga: Whāia, Whānui rānei
Ko te wāhanga whānui o Nichrome e mahi ana i ngā hiahia pāmahana iti ki te waenga: Ni60Cr15 mō ngā whakamahana whare iti, Ni70Cr30 mō ngā miro tōhi arumoni. Engari, ko te Ni80, e aro ana ki ngā tono pāmahana teitei: ka whakakaha i ngā oumu sintering ahumahi (he mea nui te ōritetanga o te pāmahana) me ngā pūnaha tango hukapapa rererangi (he mea nui te ātete ki ngā huringa makariri/wera nui). Kua whakamanahia tā mātou Ni80 mō te ASTM B162 (ngā paerewa rererangi) me te ISO 9001, e whakarite ana i te pono i roto i ēnei mara uaua.
Me pēhea te whiriwhiri i waenga i a rātou?
- Kōwhiria te nichrome whānui (hei tauira, Ni60Cr15, Ni70Cr30) mēnā: Me hiahia koe ki te whakamahana pāmahana waenga-iti (<1000°C) me te whakatairanga i te whai huatanga utu (hei tauira, ngā taputapu whare, ngā whakamahana iti).
- Kōwhiria te Ni80 mēnā: E hiahia ana koe ki te pumau i te pāmahana teitei (>1000°C), he roa te ora mahi (10,000+ hāora), he mahi rānei i roto i ngā ahumahi nui (te rererangi, te hanga ahumahi).
Ka tukuna e tā mātou tīmangā kōrerorero kore utu—mā mātou koe e āwhina ki te whakataurite i te momo nichrome tika (tae atu ki te Ni80) ki tō tono, kia pai ai te mahi me te whai hua o te utu.
