ʻO ka mea mua, he mea nui e wehewehe i kā lākou pilina:Nichrome(pōkole no ka nickel-chromium alloy) he ʻāpana ākea o nā alloys nickel-chromium-based, ʻoiaiNi80he ʻano kikoʻī o ka nichrome me kahi haku paʻa (80% nickel, 20% chromium). Aia ka "ʻokoʻa" ma ka "ʻano maʻamau vs. ʻokoʻa kikoʻī"—No ka ʻohana nichrome ʻo Ni80 akā loaʻa iā ia nā waiwai kūʻokoʻa ma muli o kona paʻa ， kūpono ia no nā hiʻohiʻona wela kiʻekiʻe. Aia ma lalo kahi hoʻohālikelike kikoʻī:
| Aspect | Nichrome (Waehana Nui) | Ni80 (Keʻano Nichrome Kūikawā) |
| Wehewehe | ʻO kahi ʻohana o nā mea hoʻohui i haku ʻia me ka nickel (50–80%) a me ka chromium (10–30%), me nā mea hoʻohui koho (e laʻa, hao) | ʻO kahi ʻano nichrome premium me ka haku mele ʻana: 80% nickel + 20% chromium (ʻaʻohe mea hoʻohui hou) |
| Hiki i ka haku mele | Nā lakio nickel-chromium like ʻole (eg, Ni60Cr15, Ni70Cr30) e hoʻokō i nā pono like ʻole | Paʻa 80:20 nickel-chromium ratio (ʻaʻohe maʻalahi i nā ʻāpana kumu) |
| Hana Nui | ʻO ke kūpaʻa wela kiʻekiʻe (800–1000°C), ka pale ʻana i ka oxidation kumu, a me ke kūpaʻa uila hiki ke hoʻololi. | ʻOi aku ka maikaʻi o ka pale ʻana i ka wela kiʻekiʻe (a hiki i 1200°C), ʻoi aku ka maikaʻi o ka pale ʻana i ka oxidation (ka haʻahaʻa haʻahaʻa ma 1000°C+), a me ke kūpaʻa uila paʻa (1.1–1.2 Ω/mm²) |
| Nā noi maʻamau | ʻO nā hiʻohiʻona hoʻomehana wela waena (e laʻa, nā mea hoʻomehana hale, nā mea wela liʻiliʻi, nā mea hoʻomehana ʻenehana haʻahaʻa) | ʻO nā hiʻohiʻona kiʻekiʻe, makemake nui (e laʻa, nā wili umu ahi, nā wela wela o ka mīkini paʻi 3D, nā mea aerospace de-icing) |
| Nā palena | Haʻahaʻa kiʻekiʻe wela; ʻokoʻa ka hana ma ka lakio kikoʻī (hoʻololi koke kekahi mau ʻano i nā manawa kiʻekiʻe) | ʻOi aku ka nui o ke kumukūʻai maka; ʻoi aku ka pono no nā hiʻohiʻona haʻahaʻa haʻahaʻa (ʻaʻole kumu kūʻai) |
1. Hoʻohui: Paʻa vs
ʻO Nichrome ma ke ʻano he ʻāpana e hiki ai ke hoʻololi i nā lakio nickel-chromium e kaulike i ke kumukūʻai a me ka hana. No ka laʻana, hoʻohui ʻo Ni60Cr15 (60% Ni, 15% Cr) i ka hao e hōʻemi i ke kumukūʻai akā hoʻohaʻahaʻa i ka pale wela. I ka hoʻokaʻawale ʻana, loaʻa iā Ni80 kahi ratio nickel-chromium non-negotiable 80:20-ʻo kēia maʻiʻo nickel kiʻekiʻe ke kumu i ʻoi aku ai ia ma mua o nā ʻano ʻano nichrome ʻē aʻe i ka pale ʻana i ka oxidation a me ka hoʻomanawanui wela. Hoʻopili paʻa kā mākou Ni80 i ka maʻamau 80:20, me ka pololei o ka haku mele ʻana i loko o ± 0.5% (hoʻāʻo ʻia ma o ka spectroscopy absorption atomic).
2. Hoʻokō: Specialized vs. General-Purpose
No nā pono wela kiʻekiʻe (1000-1200 ° C), ʻaʻole kūlike ʻo Ni80. Mālama ʻo ia i ka paʻa paʻa i nā kiln ʻoihana a i ʻole nā mea paʻi paʻi 3D wela wela, aʻo nā nichrome ʻē aʻe (e laʻa, Ni70Cr30) hiki ke hoʻomaka i ka oxidizing a i ʻole deforming ma luna o 1000°C. Eia nō naʻe, no nā hana wela haʻahaʻa haʻahaʻa (e laʻa, kahi mea hoʻomaloʻo lauoho 600°C), ʻaʻole pono ka hoʻohana ʻana iā Ni80-ʻoi aku ka maikaʻi o nā ʻano ʻano nichrome. Hoʻopili kā mākou laina huahana iā Ni80 (no nā hiʻohiʻona kiʻekiʻe-koi) a me nā nichrome ʻē aʻe (no nā kumu kūʻai, nā haʻahaʻa haʻahaʻa haʻahaʻa).
3. Noi: Kuhi ʻia vs. Wide-Ranging
Hāʻawi ka ʻāpana ākea o Nichrome i nā pono wela haʻahaʻa a i waena: Ni60Cr15 no nā mea hoʻomehana hale liʻiliʻi, Ni70Cr30 no nā filament toaster kalepa. ʻO Ni80, ma ka ʻokoʻa, hoʻopaʻa ʻia i nā noi kiʻekiʻe, kiʻekiʻe-mehana: hoʻohana ia i nā kapuahi hoʻoheheʻe ʻenehana (kahi koʻikoʻi ka like ʻana o ka mahana) a me nā ʻōnaehana aerospace de-icing (kahi e pono ai ke kū'ē i ke anuanu / wela nui). Hoʻopaʻa ʻia kā mākou Ni80 no ASTM B162 (aerospace standards) a me ISO 9001, e hōʻoiaʻiʻo ana i ka hilinaʻi i kēia mau kahua koi.
Pehea e koho ai ma waena o lākou?
- E koho i ka nichrome maʻamau (e laʻa, Ni60Cr15, Ni70Cr30) inā: Pono ʻoe i ka hoʻomehana wela ma waena o ka haʻahaʻa (<1000°C) a e koho mua i ka pono o ke kumu kūʻai (e laʻa, nā mea hana hale, nā mea hoʻomehana liʻiliʻi).
- E koho iā Ni80 inā: Pono ʻoe i ke kūpaʻa wela kiʻekiʻe (>1000°C), ke ola lōʻihi (10,000+ hola), a i ʻole e hana i nā ʻoihana koʻikoʻi (aerospace, hana hana ʻoihana).
Hāʻawi kā mākou huikūkākūkā manuahi—e kōkua mākou iā ʻoe e hoʻohālikelike i ka ʻano nichrome kūpono (me Ni80) i kāu noi kikoʻī, e hōʻoia i ka hana maikaʻi loa a me ka maikaʻi o ke kumukūʻai.
