Product Description
Manganin Hlau yog tooj liab-nickel alloys uas yog siv rau kev siv hluav taws xob thiab kev tswj xyuas kev ua haujlwm. Cov alloys no muaj qhov kub tsis tshua muaj coefficient ntawm kev ua haujlwm, thiab muaj cov hluav taws xob tsis zoo nyob rau lub sijhawm ntev. Tsis tas li ntawd, lawv muaj tsawg heev thermal electromotive force (EMF) tiv thaiv tooj liab. Cov hlau no muaj kev ua haujlwm zoo, tuaj yeem ua tau zoo, thiab welded.
