Tha Alloy FeCrAl na alloy teas àrd-aghaidh agus dealain. Faodaidh alloy fecral teòthachd pròiseas 2192 gu 2282 F a ruighinn, a rèir teòthachd an aghaidh 2372F.
Gus comas an-aghaidh oxidation a leasachadh agus beatha obrach àrdachadh, mar as trice bidh sinn a’ cur talamh tearc ris an alloy, leithid La + Ce, Yttrium, Hafnium, Zirconium, msaa.
Mar as trice bidh e air a chleachdadh ann an fùirneis dealain, hoban mullach glainne, teasadairean tiùb quartz, resistors, inneal-tionndaidh catalytach, eileamaidean teasachaidh msaa.
0Cr27Al7Mo2 Mion-sgrùdadh Ainmeil
27.00 Cr, 7.00 Al, 2.00 Mo, Bal. Fe
Teòthachd obrach leantainneach as àirde: 1400 C.
Trast-thomhas uèir: 0.5 ~ 12mm
Teòthachd leaghaidh: 1520 C
Seasmhachd dealain: 1.53 ohm mm2/m
Chaidh a chleachdadh gu mòr mar eileamaidean teasachaidh ann an fhùirneisean gnìomhachais agus àthan dealain.
Tha nas lugha de neart teth aige na aloidhean Tophet ach puing leaghaidh mòran nas àirde.
