FeCrAl alloy 0Cr27Al7Mo2 CrAl kutentha kwambiri kukana Alloy Resistance Wire
FeCrAl alloy ndi high resistancec ndi magetsi otentha aloyi. Fecral alloy imatha kufikira kutentha kwa 2192 mpaka 2282 F, molingana ndi kutentha kwa 2372F.
Pofuna kupititsa patsogolo luso la anti-oxidation ndikuwonjezera moyo wogwira ntchito, nthawi zambiri timayika zowonjezera zapadziko lapansi mu alloy, monga La+Ce, Yttrium, Hafnium, Zirconium, etc.
Nthawi zambiri amagwiritsidwa ntchito mung'anjo yamagetsi, ma hobs apamwamba agalasi, ma quartz tube heaters, resistors, chosinthira chothandizira, zinthu zotenthetsera ndi zina.
0Cr27Al7Mo2 Kusanthula Mwadzina
27.00 Cr, 7.00 Al, 2.00 Mo, Bal. Fe
Kutentha kopitilira muyeso: 1400 C.
Waya awiri: 0.5 ~ 12mm
Kutentha kosungunuka: 1520 C
Kukaniza kwamagetsi: 1.53 ohm mm2/m
Zakhala zikugwiritsidwa ntchito kwambiri ngati zinthu zotenthetsera m'ng'anjo zamakampani ndi zida zamagetsi.
Imakhala ndi mphamvu zotentha pang'ono kuposa ma aloyi a Tophet koma malo osungunuka kwambiri.
Malingaliro a kampani Shanghai TANKII ALOY MATERIAL Co., Ltd.
