Hai-Nicr70 Flat Waya ya Double Strip Coils Braking Resistor
Hai-Nicr70 Flat WayazaMa Coils Awiri Awiri Braking Resistor
Ni70Cr30ndi nickel-chromium alloy (NiCr alloy) yodziwika ndi kukana kwambiri, kukana kwa okosijeni wabwino komanso kukhazikika kwa mawonekedwe abwino kwambiri.Ndi yoyenera kugwiritsidwa ntchito pa kutentha mpaka 1250 ° C, ndipo imakhala ndi moyo wapamwamba wa utumiki poyerekeza ndi ma aloyi a Iron chromium aluminium.
Zomwe zimagwiritsidwa ntchito pa Ni70Cr30 ndi zinthu zotenthetsera zamagetsi m'zida zam'nyumba, ng'anjo zam'mafakitale ndi zopinga (zopinga zamawaya, zotchingira filimu zachitsulo), zitsulo zosalala, makina okusita, zotenthetsera madzi, pulasitiki akamafa, zitsulo zogulitsira, zitsulo zomata zitsulo ndi zinthu za cartridge.
