Product Description

NI90Cr10, tseem hu ua Nichrome 90 los yog NiCr 90/10, yog ib tug high-kev ua tau zoo alloy uas muaj zoo heev tiv taus kub thiab corrosion. Nws muaj lub siab melting point ntawm ib ncig ntawm 1400 ° C (2550 ° F) thiab tuaj yeem tswj nws lub zog thiab ruaj khov txawm tias qhov kub siab tshaj 1000 ° C (1832 ° F).

Cov hlau no feem ntau yog siv rau hauv cov ntawv thov uas xav tau cov khoom cua sov, xws li hauv cov tshuab ua kom sov, qhov cub, thiab cov khoom siv cua sov. Nws kuj yog siv rau hauv kev tsim cov thermocouples, uas yog siv los ntsuas qhov kub thiab txias hauv ntau yam txheej txheem.

NI90Cr10 muaj kev tiv thaiv zoo heev rau oxidation, uas ua rau nws muaj txiaj ntsig tshwj xeeb hauv qhov chaw kub kub uas lwm cov ntaub ntawv yuav sai sai corrode thiab degrade. Nws kuj muaj cov khoom siv zoo, xws li lub zog tensile siab thiab zoo ductility, uas ua rau nws yooj yim rau kev tsim thiab zoo.

Thaum nws los txog rau cov kav dej ua los ntawm cov hlau no, lawv feem ntau yog siv rau hauv cov ntawv thov uas muaj qhov kub thiab txias, xws li kev ua tshuaj lom neeg, petrochemical, thiab hluav taws xob tsim kev lag luam. Cov khoom tshwj xeeb ntawm cov yeeb nkab, xws li nws qhov loj me, phab ntsa tuab, thiab kev ntsuas siab, yuav nyob ntawm qhov kev siv thiab cov kev cai tshwj xeeb ntawm qhov project.
