Constantan Hlau nrog nruab nrab resistivity thiab tsis tshua muaj kub coefficient ntawm tsis kam nrog lub tiaj tsis kam / kub nkhaus hla qhov dav dua li "manganins". Constantan kuj qhia tau hais tias corrosion kuj zoo dua li tus txiv neej ganins. Kev siv yuav raug txwv rau ac circuits.
Constantan hlau kuj yog qhov tsis zoo ntawm hom J thermocouple nrog Hlau yog qhov zoo; Hom J thermocouples yog siv rau hauv kev kho cua sov. Tsis tas li, nws yog qhov tsis zoo ntawm hom T thermocouple nrog OFHC Copper qhov zoo; Hom T thermocouples yog siv rau ntawm qhov kub thiab txias.
Copper nickel alloy series: Constantan CuNi40 (6J40), CuNi1, CuNi2, CuNi6, CuNi8, CuNi10, CuNi14, CuNi19, CuNi23, CuNi30, CuNi34, CuNi44.

Shanghai Tankii Alloy Material Co., Ltd. tsom rau kev tsim cov hlau tsis kam (nichrome Alloy, FeCrAl Alloy, tooj liab nickel alloy, thermocouple hlau, precision alloy thiab thermal spray alloy nyob rau hauv daim ntawv ntawm hlau, ntawv, daim kab xev, sawb, pas nrig thiab phaj.
Shanghai Tankii Alloy Material Co., Ltd tau sau ntau yam kev paub dhau los 35 xyoo hauv daim teb no. Nyob rau hauv xyoo tas los no, ntau tshaj 60 tus thawj tswj hwm cov neeg tseem ceeb thiab cov txuj ci kev tshawb fawb thiab thev naus laus zis tau ua haujlwm. Lawv tau koom nrog txhua txoj kev taug kev ntawm lub tuam txhab lub neej, uas ua rau peb lub tuam txhab ua kom tawg paj thiab invincible hauv kev sib tw ua lag luam. Raws li lub hauv paus ntsiab lus ntawm "thawj qhov ua tau zoo, kev pabcuam siab dawb", peb cov kev tswj hwm lub tswv yim tab tom nrhiav kev tsim kho thev naus laus zis thiab tsim cov khoom lag luam saum toj kawg nkaus hauv kev lag luam alloy. Peb pheej nyob rau hauv Zoo – lub hauv paus ntawm kev ciaj sia. Nws yog peb txoj kev xav mus ib txhis los pab koj nrog lub siab thiab tus ntsuj plig. Peb tau cog lus los muab cov neeg siv khoom thoob plaws ntiaj teb nrog cov khoom zoo, cov khoom sib tw thiab cov kev pabcuam zoo meej.
Peb cov khoom, xws li peb nichrome alloy, precision alloy, thermocouple hlau, fecral alloy, tooj liab nickel alloy, thermal spray alloy tau raug xa tawm mus rau ntau tshaj 60 lub teb chaws hauv ntiaj teb. Peb txaus siab los tsim kom muaj kev sib koom tes ntev thiab ntev nrog peb cov neeg siv khoom. Feem ntau ua tiav ntau yam ntawm cov khoom mob siab rau Resistance, Thermocouple thiab Furnace manufacturers Zoo nrog rau qhov kawg ntawm kev tsim khoom tswj Kev txhawb nqa thiab Kev Pabcuam Cov Neeg Siv Khoom.
