Tlhaloso: J707Ni ke electrode ea tšepe e nang le alloy e tlaase e nang le matla a tlaase a nang le sodium e tlaase.Sebelisa DCEP (electrode e nepahetseng hona joale) 'me e ka chesetsoa maemong ohle.Tšepe e kentsoeng e na le thepa e ntle ea mochini.Ha ho bapisoa le electrode ea J707, tšobotsi e ka sehloohong ea J707Ni ke hore mocheso o tlase o thata le ho hanyetsa ho phatloha ho ntlafalitsoe haholo.
Kopo: E sebelisetsoa ho tjheseletsa meaho ea tšepe e nang le alloy e phahameng ea matla a matla a lekanang, joalo ka 14MnMoVB, WEL-TEN70 le Japanese HW56 le meaho e meng ea tšepe e nang le alloy e phahameng e matla.
