Sharaxaad: J707Ni waa bir bir ah oo bir ah oo aad u hooseeya oo leh daahan sodium-hydrogen hooseeya.Isticmaal DCEP (electrode toos ah oo toos ah) waxaana lagu alxan karaa dhammaan boosaska.Birta la dhigo waxay leedahay sifooyin farsamo oo wanaagsan.Marka la barbar dhigo electrode J707, muuqaalka ugu weyn ee J707Ni waa in heerkulka hoose ee adkaanta iyo caabbinta dillaac ayaa si weyn loo hagaajiyey.
Codsiga: Waxaa loo isticmaalaa alxanka qaab-dhismeedyada birta-hooseeya ee xoogga badan ee heerarka xoogga u dhigma, sida 14MnMoVB, WEL-TEN70 iyo Japanese HW56 iyo dhismooyinka kale ee hoose ee birta xoogga badan.

Ogaysiis:
1. electrode waa in lagu dubaa 1 saac at 350 ~ 380 ℃ ka hor hawlgalka alxanka;
2. Waa lagama maarmaan in la nadiifiyo miridhku, miisaanka saliidda, biyaha, iyo wasakhda qaybaha alxanka ka hor;
3. Isticmaal qalliin gaaban marka alxanka la samaynayo.Jidka alxanka cidhiidhiga ah ayaa habboon.
