Nikeli Chromium Alloy Ni80cr20 Uaea Mafolafola Elemene Vevela
Nickel Chromium AlloyNi80cr20 Uaea Flat Elemene Vevela
O le Ni80Cr20 o se nickel-chromium alloy (NiCr alloy) E mafai ona maua ai ni paʻu mafiafia lelei faʻapipiʻi ma sili ona lelei masini, eletise eletise ma le maualuga o le vevela faʻamaʻi e oʻo atu i le 1800 tikeri F (980 tikeri C), ma o loʻo i ai se olaga sili atu le auaunaga pe a faʻatusatusa i le Umea. chromium alumium alloys.It faaalia exothermic vevela ao faaaogaina
Talosaga:
O talosaga masani mo Ni80Cr20 e eletiseelemene faamafanafanas i meaafale fale, ogaumu alamanuia ma tetee (tetee uaea, uamea tetee ata tifaga), uʻamea mafolafola, masini auli, vai vevela, palasitika paʻu oti, uʻamea soli, uʻamea sheathed tubular elemene ma elemene cartridge. Normal composition%
