Choyamba, ndikofunikira kufotokozera ubale wawo:Nichrome(chidule cha nickel-chromium alloy) ndi gulu lalikulu la ma aloyi a nickel-chromium, pomweNdi80ndi mtundu wina wa nichrome wokhala ndi mawonekedwe osasunthika (80% nickel, 20% chromium). "Kusiyana" kuli mu "gulu lazonse motsutsana ndi zosiyana zenizeni" -Ni80 ndi ya banja la nichrome koma ili ndi katundu wapadera chifukwa chosasunthika ,kupangitsa kuti ikhale yoyenera kwa zochitika zapadera zotentha kwambiri. Pansipa pali kufananitsa mwatsatanetsatane:
| Mbali | Nichrome (General Category) | Ni80 (Specific Nichrome Variant) |
| Tanthauzo | Banja la ma alloys makamaka lopangidwa ndi faifi tambala (50-80%) ndi chromium (10-30%), zokhala ndi zowonjezera (mwachitsanzo, chitsulo) | Mtundu wapamwamba wa nichrome wokhala ndi mawonekedwe okhwima: 80% faifi tambala + 20% chromium (palibe zowonjezera) |
| Kusinthasintha Kopanga | Zosintha za nickel-chromium (mwachitsanzo, Ni60Cr15, Ni70Cr30) kukwaniritsa zosowa zosiyanasiyana | Chiyerekezo cha 80:20 nickel-chromium (palibe kusinthasintha m'magawo apakati) |
| Magwiridwe Ofunika | Kutentha kwapakati (800-1000 ° C), kukana kwa okosijeni, komanso kukana kwamagetsi kosinthika. | Kutentha kwapamwamba kwambiri (mpaka 1200 ° C), kukana kwa okosijeni kwabwino (kutsika pang'ono pa 1000 ° C+), komanso kukana kwamagetsi kosasunthika (1.1-1.2 Ω/mm²) |
| Ntchito Zofananira | Kutentha kwapakati-kutsika (monga machubu otenthetsera zida zapakhomo, zoyatsira zing'onozing'ono, zotenthetsera zamakampani zotsika mphamvu) | Kutentha kwambiri, komwe kumafunikira kwambiri (mwachitsanzo, ma coil a ng'anjo ya mafakitale, zowotcha zosindikizira za 3D, zinthu zowotcherera ndege) |
| Zolepheretsa | Kutsika kwakukulu kutentha; magwiridwe antchito amasiyanasiyana malinga ndi chiŵerengero chapadera (mitundu ina imatulutsa okosijeni mwachangu pakatentha kwambiri) | Mtengo wokwera wazinthu zopangira; oyenerera pazochitika zotsika kwambiri (osati zotsika mtengo) |
1. Zolemba: Zokhazikika vs. Flexible
Nichrome monga gulu imalola ma nickel-chromium osinthika kuti azitha kuwerengera mtengo ndi magwiridwe antchito. Mwachitsanzo, Ni60Cr15 (60% Ni, 15% Cr) amawonjezera chitsulo kuti achepetse mtengo koma amachepetsa kutentha. Mosiyana ndi izi, Ni80 ili ndi chiŵerengero cha 80:20 cha nickel-chromium chosakambitsirana-chiwerengero cha nickel chapamwamba ichi ndichifukwa chake chimaposa mitundu ina ya nichrome pakukana kwa okosijeni ndi kulolera kutentha. Ni80 yathu imatsatira mosamalitsa muyezo wa 80:20, wokhala ndi zolondola mkati mwa ± 0.5% (zoyesedwa kudzera pa mayamwidwe a atomiki).
2. Magwiridwe: Mwapadera vs. General-Cholinga
Pazofunika kutentha kwambiri (1000-1200 ° C), Ni80 ndi yosayerekezeka. Imasunga bata m'mafakitale kapena makina osindikizira a 3D otentha, pomwe nichrome ina (mwachitsanzo, Ni70Cr30) imatha kuyambitsa oxidizing kapena kupunduka pamwamba pa 1000 ° C. Komabe, pa ntchito zotentha zapakatikati (mwachitsanzo, chowumitsa tsitsi cha 600 ° C), kugwiritsa ntchito Ni80 sikofunikira - mitundu yotsika mtengo ya nichrome imagwira ntchito bwino. Zogulitsa zathu zimaphatikiza zonse za Ni80 (zofuna kwambiri) ndi zina za nichrome (zofuna zotsika mtengo, zotsika kwambiri).
3. Ntchito: Chandage vs. Wide-Ranging
Gulu lalikulu la Nichrome limapereka zosowa zosiyanasiyana za kutentha kwapakati mpaka pakati: Ni60Cr15 paziwotcha zazing'ono zapakhomo, Ni70Cr30 zamafilanti opangira zitsulo zamalonda. Ni80, mosiyana, imayang'ana ntchito zapamwamba, zotentha kwambiri: zimapereka mphamvu ku ng'anjo za mafakitale (komwe kutentha kumakhala kofunikira) ndi makina oyendetsa ndege (komwe kukana kuzizira kwambiri / kutentha kumakhala kofunika). Ni80 yathu ndi yovomerezeka ya ASTM B162 (miyezo yazamlengalenga) ndi ISO 9001, kuwonetsetsa kudalirika m'magawo ovutawa.
Momwe Mungasankhire Pakati pawo?
- Sankhani nichrome wamba (monga, Ni60Cr15, Ni70Cr30) ngati: Mukufuna kutentha kwapakati (<1000°C) ndikuyika patsogolo kusawononga ndalama (mwachitsanzo, zida zapakhomo, zoyatsira zing'onozing'ono).
- Sankhani Ni80 ngati: Mukufuna kukhazikika kwa kutentha kwakukulu (> 1000 ° C), moyo wautali wautumiki (maola 10,000+), kapena kugwira ntchito m'mafakitale ovuta (zamlengalenga, kupanga mafakitale).
Gulu lathu limaperekakufunsira kwaulere-tikuthandizani kuti mufanane ndi mtundu woyenera wa nichrome (kuphatikiza Ni80) ndi pulogalamu yanu yeniyeni, kuwonetsetsa kuti mukuchita bwino komanso kuti mtengo wake ndi wotsika kwambiri.
