Atụmatụ na uru
1. High iji okpomọkụ, kacha iji okpomọkụ nwere ike iru 1400C (0Cr21A16Nb, 0Cr27A17Mo2, wdg)
2. Obere okpomọkụ ọnụọgụ nke nguzogide
3. Ọnụego mgbasawanye okpomọkụ dị ala karịa Ni-base super-alloys.
4. Igwe ọkụ eletrik dị elu
5. Ezigbo nguzogide corrosion n'okpuru okpomọkụ dị elu, karịsịa n'okpuru ikuku nwere sulfide
6. Ibu elu elu
7. Na-eguzogide ọgwụ
8. Lower raw-material cost, Lower density and cheaper price tụnyere Nichrome waya.
9. Nguzogide oxidation kacha elu na 800-1300ºC
10. Ogologo oge ndu
