Enamelled CuNi45 / CuNi44 / CuNi40 tooj liab nickel Alloy Hlau
Enamelled CuNi45 / CuNi44 / CuNi40 Alloy Hlau
Product Description
Cov enameled kuj nyob ntawm tej no tau dav siv rau tus qauv resistors, tsheb
qhov chaw, winding resistors, thiab lwm yam. siv cov txheej txheem rwb thaiv tsev zoo tshaj plaws rau cov ntawv thov no, ua kom zoo dua ntawm cov yam ntxwv ntawm cov txheej txheej txheej.
Tsis tas li ntawd, peb yuav ua cov enamel txheej rwb thaiv tsev ntawm cov hlau zoo nkauj xws li nyiaj thiab platinum hlau raws li kev txiav txim. Thov siv qhov kev tsim khoom no-on-order.
Hom liab Alloy hlau
Cov hlau peb tuaj yeem ua enamelled yog tooj liab-nickel alloy hlau, Constantan hlau, Manganin hlau. Kama Hlau, NiCr Alloy hlau, FeCrAl Alloy hlau thiab lwm yam hlau hlau

Kev siv Constantan
Constantan yog ib qho tooj liab-nickel alloy uas muaj qhov tshwj xeeb me me ntxiv
cov ntsiab lus kom ua tiav qhov tseem ceeb rau qhov kub coefficient ntawm resistivity. Ceev faj
kev tswj ntawm melting thiab hloov dua siab tshiab coj ua nyob rau hauv ib tug heev tsawg theem ntawm pinholes ntawm
ultra nyias thicknesses. Lub alloy yog siv dav rau cov ntawv ci resistors thiab strain gauges.
