Thermal-based low resistance alloy imagwiritsidwa ntchito kwambiri mu low-voltage circuit breaker, thermal overload relay, ndi zinthu zina zamagetsi zotsika. Ndi chimodzi mwazinthu zofunikira kwambiri zamagetsi zamagetsi zotsika kwambiri. Zida zopangidwa ndi kampani yathu zimakhala ndi mawonekedwe abwino otsutsa komanso kukhazikika kwapamwamba. Titha kupereka mitundu yonse ya waya wozungulira, lathyathyathya ndi pepala zipangizo.
CuNi40(6J40)
Constantanndi CuNi40, yomwe imatchedwanso 6J40, ndi aloyi yotsutsa yomwe imapangidwa makamaka ndi mkuwa ndi faifi tambala.
Ili ndi kutentha kocheperako kukana, kuchuluka kwa kutentha kogwira ntchito (500 pansipa), makina abwino opangira, odana ndi dzimbiri komanso kuwotcherera mosavuta.
Aloyiyo si maginito. Imagwiritsidwa ntchito pamagetsi osinthika a regenerator ndi resistor strain,
potentiometers, mawaya otentha, zingwe zotenthetsera ndi mphasa. Ma riboni amagwiritsidwa ntchito kutenthetsa ma bimetals. Ntchito inanso ndikupanga ma thermocouples chifukwa imapanga mphamvu yamagetsi yamagetsi (EMF) polumikizana ndi zitsulo zina.
Copper nickel alloy series:Constantan CuNi40 (6J40), CuNi1, CuNi2, CuNi6, CuNi8, CuNi10, CuNi14, CuNi19, CuNi23,CuNi30, CuNi34, CuNi44.
