Yakajairika saizi yeNickel alloy waya:

Isu tinopa zvigadzirwa muchimiro chewaya, flat wire, strip.

Waya inopenya uye chena-0.025mm ~ 3mm

Pickling waya: 1.8mm ~ 10mm

Oxidized waya: 0.6mm ~ 10mm

Flat waya: ukobvu 0.05mm ~ 1.0mm, upamhi 0.5mm ~ 5.0mm

Maitiro:

Waya:Kugadzira zvinhu →kunyunguduka →kunyunguduka →kunyunguduka →kuumburudza →kupisa

Zvigadzirwa zve nichrome waya:

1) Yakanakisa anti-oxidation uye simba remagetsi pakupisa kwakanyanya;

2) High resistivity uye yakaderera tembiricha coefficient yekupikisa;

3) Yakanakisa reelability uye kugadzira kuita;

4) Yakanakisa welding performanceace
