Waya yeNickel Chromium Ni80Cr20+Nb Alloy Waya Yakanaka Kudzivirira Kupisa Kwepamusoro
Ruzivo rwechigadzirwa:
Kuumbwa kweMakemikoro: Nickel 80%, Chrome 20% +Nb
Mamiriro: Ruvara rwakajeka/ruchena rweasidhi/rwakasanganiswa neokisijeni
Dhayamita: Inogona kugadziriswa
China NiCr chiwanikwa waya mugadziri
Kuumbwa kweMakemikoro uye Hunhu Hwawo:

Saizi yenguva dzose:
Tinopa zvigadzirwa zvakaita sewaya, waya yakatsetseka, strip. Tinogonawo kugadzira zvinhu zvakagadzirwa zvinoenderana nezvikumbiro zvevashandisi.
Waya yakapfava, yakapfava, uye yakajeka–0.025mm ~ 5mm
Waya chena inopikira acid: 1.8mm ~ 10mm
Waya yakasanganiswa: 0.6mm ~ 10mm
Waya yakati sandara: ukobvu 0.05mm ~ 1.0mm, upamhi 0.5mm ~ 5.0mm
Maitiro:
Waya: Kugadzirira zvinhu → kunyungudutsa → kunyungudutsazve → kugadzira → kupisa kupfungaira → kupisa → kurapwa pamusoro → kudhirowa (kupfungaira) → kupedza kupisa → kuongorora → package → imba yekuchengetera zvinhu
Zvimiro zvechigadzirwa:
1) Inodzivirira oxidation uye simba remakanika rakanaka pakupisa kwakanyanya;
2) Kudzivirira kwakanyanya uye kusimba kwekupisa kwakaderera;
3) Kugona kudzokorora zvakanaka uye kugadzira mashandiro;
4) Kushanda zvakanaka kwazvo kwekushongedza
