Mimi ni watengenezaji wa waya inapokanzwa upinzani ni pamoja na
Waya wa FeCrAL, waya wa NiCr, waya wa CuNi:
II Faida kuu na Matumizi
A. Kigezo cha kimwili:
1) Kipenyo cha waya: 0.025 ~ 15mm
2) Nickel safi ina uwezo wa kuhimili joto la juu bila kuharibika. Upeo wa uendeshaji
joto ni takriban 600 ° C
3) Waya ya Nickel inapatikana katika ujenzi wa nyuzi moja au nyuzi nyingi. Imetolewa kutoka kwa hisa ama tupu, au maboksi
B. Sifa:
1) Unyoofu bora
2) Sare na hali nzuri ya uso bila matangazo
3) Uwezo bora wa kutengeneza coil
C. Maombi kuu na madhumuni ya jumla:
1) Waya hii pia inaweza kutumika sana kwa jumla maalum kwa kofia za transistor, anodi za mirija ya elektroniki,
inaongoza ya vipengele vya elektroniki / risasi-katika-waya kwa taa na kwa waya-mesh. Pia hutumiwa katika fomu ya strip kwa anuwai
maombi ikiwa ni pamoja na betri za Ni-Cd
2) Pia hutumika kwa nyaya, Lead-in-Waya kwa ajili ya taa, mirija ya elektroniki inayounga mkono, nguo ya waya inayounganisha umeme.
ambapo halijoto ni zaidi ya zile ambazo shaba inafaa kwao, kufuma kwa waya
3) Maombi ya kawaida ni pamoja na: kusitishwa kwa vitu vya kupokanzwa kama katika oveni, vifaa vya kutolea nje vya plastiki, tanuu.
Filament inasaidia na waya za kuongoza katika tasnia ya taa
