0.12mm 80/20 Nichrome Waya fun Awọn ileru Iṣẹ
Awọn alloys Nickel Chrome (NiCr) jẹ awọn ohun elo atako giga ti a lo nigbagbogbo ni awọn ohun elo pẹlu awọn iwọn otutu ti o pọ julọ ti o to 1,250°C (2,280°F).
Awọn ohun elo Austenitic wọnyi ni a mọ fun agbara ẹrọ ti o ga julọ ni awọn iwọn otutu ti a fiwe si awọn ohun elo FeCrAl bii agbara ti nrakò ti o ga julọ. Awọn ohun elo Nickel Chrome tun wa diẹ sii ductile nigbati akawe si FeCrAl alloys lẹhin awọn akoko gigun ni iwọn otutu. Chromium Oxide dudu (Cr2O3) ti wa ni akoso ni awọn iwọn otutu giga eyiti o ni ifaragba si spalling, tabi gbigbọn, nfa ibajẹ ti o pọju ti o da lori ohun elo naa. Ohun elo afẹfẹ yii ko ni awọn ohun elo idabobo itanna bi Aluminiomu Oxide (Al2O3) ti awọn ohun elo FeCrA.
