Ndi moyo wautali wautumiki.Kutentha mofulumira.Kutentha kwapamwamba kwambiri.Kutentha kofanana. Itha kugwiritsidwa ntchito molunjika. Mukagwiritsidwa ntchito mumagetsi ovotera, palibe vuto losasunthika. Ndi chitetezo cha chilengedwe waya wotentha wamagetsi. Ndipo njira ina yotsika mtengo ya nichrome waya.Ikhoza kusinthidwa malinga ndi zofuna za makasitomala
FeCrAl alloys imadziwika ndi kukana kwa okosijeni kwabwino kwambiri komanso kukhazikika kwa mawonekedwe komwe kumapangitsa moyo wautali.
Nthawi zambiri amagwiritsidwa ntchito potenthetsa magetsi m'ng'anjo zamakampani ndi zida zapanyumba.
Fe-Cr-Al alloy yokhala ndi resistivity kwambiri komanso kutentha kwa serviceability kuposa ya NiCr alloy komanso ili ndi mtengo wotsika.
Mapulogalamu
Iron-chrome-aluminium electric resistor strip imagwiritsidwa ntchito kwambiri popanga zinthu zotenthetsera zamagetsi pazida zam'nyumba ndi ng'anjo zamakampani. Zomwe zimagwiritsidwa ntchito ndi chitsulo chathyathyathya, makina ositasita, zotenthetsera madzi, kuumba pulasitiki kumafa, zitsulo zogulitsira, zitsulo zokhala ndi ma tubular ndi zinthu za cartridge.
malo ofunsira
Zogulitsa zathu zimagwiritsidwa ntchito kwambiri pazida zochizira kutentha, mbali zamagalimoto, kupanga chitsulo ndi chitsulo,
Aluminiyamu makampani, zitsulo zipangizo, petrochemical zida, galasi makina, ceramic makina,
makina azakudya, makina opanga mankhwala, ndi mafakitale opanga magetsi.
