Nickel Chromium Heat Resistance Alloy Electric Waya 2080/3070
HNickel Chromium okpomọkụ na-eguzogide alloy waya eletrik 2080/3070
A na-eji wires Nickel-Chrome eme ihe n'ọtụtụ ebe dị ka ihe mkpuchi dị elu maka ikpo ọkụ eletrik na ndị na-emegide ọnya waya na ụlọ ọrụ ọla, ụlọ ọrụ kemịkalụ na ụlọ ọrụ eletrik, wdg.
Nke a alloy waya nwere elu eletrịk iguzogide ọnụọgụ, ezigbo mgbochi oxidation na mgbochi corrosion arụmọrụ, na ọ nwekwara ezi n'ibu workability na weldability, na elu ike na elu okpomọkụ.
