Nickel Chromium NiCr Alloy
Ibikoresho bya Nickel-chromium bikoreshwa cyane mu itanura ry’amashanyarazi mu nganda, ibikoresho byo mu rugo, ibikoresho bitarengeje urugero n’ibindi bikoresho bitewe n’ubushyuhe bwo hejuru cyane hamwe na plastike ikomeye. Nickel-chromium hamwe nicyuma, aluminium, silikoni, karubone, sulfure nibindi bintu bishobora gukorwa mu nsinga ya nikel-chromium alloy wire, ifite imbaraga nyinshi zo guhangana n’ubushyuhe kandi ikaba ari ikintu gishyushya amashanyarazi y’itanura ry’amashanyarazi, icyuma kigurisha amashanyarazi, icyuma cy’amashanyarazi na ibindi bicuruzwa.
Byongeye kandi, insinga ya NiCr isanzwe ikoreshwa muri coil yo kunyerera rheostat kugirango irinde umuzunguruko kandi ihindure umuyoboro wumuzunguruko uhindura imyigaragambyo yumurongo winjira, bityo uhindure voltage hejuru yuyobora (ibikoresho byamashanyarazi) bihujwe hamwe na ni, Ikoreshwa cyane mumubare munini wibikoresho byo murugo.
NiCr Urutonde
Ni90Cr10 umurongo ni ubwoko bwa nikel-chromium ivanze, birakwiriye gukoreshwa mubushyuhe bugera kuri 1250 ° C. Ibirimo bya Chromium bitanga igihe cyiza cyubuzima, mubisanzwe bikoreshwa mubintu bishyushya vape.
Ni90Cr10 irangwa no kurwanya cyane, kurwanya okiside nziza, guhindagurika nyuma yo gukoreshwa no gusudira neza. NiCr Alloy ni ibikoresho byiza byo gushyushya inganda.
Ni90Cr10 Nickel-Chromium Nickel NiCr Alloy irwanya gushyushya impapuro
