Ni90Cr10 NiCr 90/10 Nickel Chrome Alloy waya chromel Alumel Thermocouple Head Parts
Ni90Cr10 NiCr90/10 nickel chrome alloy wayawaya wa nichromezigawo za mutu wa thermocouple
China katundu nichrome 90 Ni90
Ni90Cr10 ndi austenitic nickel-chromium alloy (NiCr alloy) yogwiritsidwa ntchito pa kutentha mpaka 1200 ° C (2190 ° F). Alloy imadziwika ndi kukana kwakukulu, kukana kwa okosijeni komanso kukhazikika kwa mawonekedwe abwino kwambiri. Ili ndi ductility wabwino pambuyo ntchito ndi weldability kwambiri.
Ni90Cr10 imagwiritsidwa ntchito pakuwotcha magetsi pazida zam'nyumba ndi ng'anjo zamakampani. Zomwe zimagwiritsidwa ntchito ndi zitsulo zosalala, makina akusita, zotenthetsera madzi, kuumba pulasitiki kumafa, zitsulo zogulitsira, zitsulo zokhala ndi ma tubular ndi zinthu za cartridge.
Chifukwa cha zomatira zabwino kwambiri za okusayidi pamwamba, Ni90C10 imapereka moyo wabwino kwambiri wautumiki poyerekeza ndi ma aloyi ampikisano a nickel-chromium.

CHROMEL vs ALUMEL imagwiritsidwa ntchito mu oxidizing, inert kapena youma kuchepetsa atmospheres. Kuwonekera kwa vacuum kumangokhala kwakanthawi kochepa. Ayenera kutetezedwa ku sulfure komanso oxidizing atmospheres. Yodalirika komanso yolondola pa kutentha kwakukulu.Chromel: Chromel ndi alloy ya 90% nickel ndi 10% chromium. Amagwiritsidwa ntchito popanga ma conductor abwino a ANSI Type E ndi Type K thermocouples, zida zoyezera kutentha zomwe zimakhala ndi ma conductor awiri osiyana.
