Constantan yog lub npe tsim rau tooj liab-nickel alloytseem hu ua Eureka, Ua Ntej, thiab Ferry. Nws feem ntau muaj 55% tooj liab thiab 45% npib tsib xee..
Dab tsi yog siv manganin?
Cov khoom lag luam ntawm Manganin®
Cov hlau no suav nrog feem ntau tooj liab (85%) nrog rau manganese (12%) thiab npib tsib xee (2%) yog thawj tsim nyob rau hauv 1892. Nyob rau hauv daim ntawv ntawm cov ntawv ci thiab hlau Nws yog siv hauv kev tsim cov resistorsvim nws qhov kub tsis zoo ntawm qhov tsis kam ntawm tus nqi thiab kev ruaj ntseg ntev.
Constantan yog dab tsi thiab nws siv qhov twg?
Constantan yog tooj liab / npib tsib xee alloy siv hauv tsim cov thermocouples thiab thermocouple txuas xov hlau raws lizoo li precision resistors thiab tsis kub tsis kam ua cua sov daim ntaub ntawv.
Puas yog Constantan lub cua sov zoo?
Constantan yog npib tsib xee thiab tooj liab-raws li alloy hlau uas muajsiab resistivitythiab yog siv rau cov thermocouples thiab hluav taws xob tiv thaiv cua sov. Nws muaj qhov ua kom tsis tu ncua ntawm qhov kub thiab txias.
Puas yog Nichrome lossis constantan zoo dua?
Nichrome, uas tsis yog-sib nqus 80/20 alloy ntawm npib tsib xee thiab chromium, yog cov hlau tsis zoo tshaj plaws rau lub hom phiaj cua sov vim tias nws muaj kev tiv thaiv siab thiab tiv thaiv oxidation ntawm qhov kub thiab txias. …Constantan [Cu55Ni45] muaj qhov kub tsis tshua muaj coefficient ntawm resistivity thiab raws li cov tooj liab alloy, yog yooj yim soldered.
