Ni80Cr20 Flat Wire Nickel Chrome Alloy ee Walxaha Kuleylinta

Nichrome 8020 siligga fidsan, oo ka kooban 70% nikkel iyo 30% chromium, waa alaab gaar ah oo alloy ah. Muuqaalkeeda fidsan waxay bixisaa dhul ballaaran oo dusha sare ah, taasoo kor u qaadaysa waxtarka daadinta kulaylka iyadoo la ilaalinayo heerkul sare oo heer sare ah. Waxay ku faantaa iska caabin koronto oo sarreeya, waxay ku habboon tahay kuleylinta qalabka warshadaha, foornooyinka, iyo codsiyada heerkulka sare ee kale. Waad ku mahadsan tahay caabbinta oksaydhka adag iyo xoogga farsamada, siligan gurigu wuxuu hubinayaa waxqabadka joogtada ah iyo nolol adeeg oo dheer, taas oo ka dhigaysa doorasho lagu kalsoonaan karo oo dalbanaysa kuleylka iyo iska caabinta - mashaariicda ku salaysan.
