FeCrAl alloy 0Cr27Al7Mo2 àrd èifeachdas teirmeach Alchrome Alloy Resistance Uèir
FeCrAl alloy 0Cr27Al7Mo2èifeachdas teirmeach àrdUèir Resistance Alchrome Alloy (Teòthachd Obrach 1400C)
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.
