E-Ni99
Magacyada Ganacsiga Guud: AWS A5.15 ENi-Ci
Dhammaan boosaska dhexdhexaadka ah ee dahaarka leh ee dhexdhexaadka ah, graphite-ku-salaysan ee kabka birta ah.Waxay dhigataa nikkel iyo birta daawaynta birta, kaas oo ah ductile iyo mashiinka la samayn karo, isagoo ku biiraya noocyo kala duwan oo birta ah oo ay ku jiraan birta shubka nodular.

Waa maxay sababta E-Ni99?
1) Nikkel saafi ah
2) awood dhimis xoog leh
3) nooca graphite electrode
4) alxanka: ma jiro preheating, iska caabin dildilaac wanaagsan iyo machinability 5) ku haboon AC iyo DC
6) ilaa xad qaali ah
7) loo isticmaalo qaybo kabka alxanka khafiifka ah iyo dayactirka sagxadaha alxanka sida madaxyada dhululubada, saldhigyada mishiinka, sanduuqyada geeraarka iyo birta birta ah
Goobta Codsiga ee E-Ni99:
Ku habboon isku xirka biraha aan birta ahayn iyo kuwa birta ah, shubista culus ee u baahan farsamaynta, hagaajinta shubka jajaban, daboolka mishiinka, guryaha bamka, caaryada qallalan
