Uchambuzi wa majina
27.00 Cr, 7.00 Al, 2.00 Mo, Bal. Fe
Kiwango cha juu cha joto cha kufanya kazi: 1400 C.
Kipenyo cha waya: 0.5 ~ 12mm
Kiwango cha kuyeyuka: 1520 C
Upinzani wa Umeme: 1.53 ohm mm2/m
Imetumika sana kama vifaa vya kupokanzwa katika tanuu za viwandani na tanuu za umeme.
Ina nguvu kidogo ya joto kuliko aloi za Tophet lakini kiwango cha juu zaidi cha kuyeyuka.
