Saizi yenguva dzose:
Tinopa zvigadzirwa zvakaita sewaya, waya yakatsetseka, strip. Tinogona kutsigira kugadzirisa;
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 → kunyunguduka → kunyungudukazve → kuumba → kupisa kunopfungaira → kurapwa kwekupisa
→kurapa pamusoro pechinhu →kudhirowa (kumonereka) →kurapa kupisa kwekupedzisira →kutarisa →pakeji →dura
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
