Nickel Chromium NiCr Alloy
Qalabka nickel-chromium waxaa si weyn loogu isticmaalaa foornooyinka korontada ee warshadaha, qalabka guriga, qalabka fog-infrared iyo qalabka kale sababtoo ah awooddooda heerkul sare oo aad u fiican iyo caag adag. Nickel-chromium iyo iron, aluminium, silicon, carbon, sulfur iyo walxo kale ayaa laga samayn karaa silig nikkel-chromium alloy, kaas oo leh iska caabin sare iyo caabbinta kulaylka waana cunaha kuleylka korontada ee foornada korontada, birta alxanka korontada, birta korontada iyo alaabta kale.
Intaa waxaa dheer, silig NiCr waxaa sida caadiga ah loo isticmaalaa in gariiradda rheostat simbiriirixan si ay u ilaaliyaan wareegga iyo beddelo hadda ee wareegga by beddelo iska caabin ah ee qaybta wareegga helitaanka, oo sidaas beddelo danab guud ahaan kaari (qalabka korontada) ku xiran si taxane ah oo leh. Waxaa si weyn loogu isticmaalaa tiro badan oo ah qalabka guriga.
NiCr Alloy Taxanaha
Xarigga Ni90Cr10 waa nooc ka mid ah alaabada daawaha ee nikkel-chromium, waxay ku habboon tahay codsiyada heerkulka ilaa 1250 ° C. Waxyaabaha ku jira Chromium waxay ku siinayaa waqti nololeed oo aad u wanaagsan, inta badan waxaa loo isticmaalaa sidii walxaha kuleyliyaha vape.
Ni90Cr10 waxaa lagu gartaa iska caabin sare, iska caabin oksaydh wanaagsan, ductility wanaagsan ka dib isticmaalka iyo alxanka heer sare ah. NiCr Alloy waa wax wanaagsan oo loogu talagalay warshadaha kuleylka.
