Saizi yenguva dzose yewaya yeNickel alloy:

Tinopa zvigadzirwa zvakaita sewaya, waya yakatsetseka, strip. Tinogonawo kugadzira zvinhu zvakagadzirwa zvinoenderana nezvikumbiro zvevashandisi.

Waya inopenya uye chena–0.025mm ~ 3mm

Waya yekunatsa: 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 che nichrome waya:

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
