High Temperature Resistant Enameled Winding Wire Constantan Corrosion Resistance
0.15mm Constantan/ Manganin 1UEW/155 Enamelled Wire/ Varnished Wire
Constantan is a copper-nickel alloy that contains small amounts specific to others
elements to achieve precise values of the resistivity of the temperature coefficient. The fusion control and conversion practices bring a very low level of holes of ultra-thin thickness.
Aluminum alloy is widely used for resistors and voltage meters.
Our company produces alloy sheet, metal sheet, steel sheet with thickness 0.005mm-0.1mm (5um-100um), width 1mm-1330mm
The company also offers: cuni1 cuni2 cuni6 cuni8 cuni10 cuni19 cuni19 cuni30 cuni34 cuni44 cumn3 and constantan 6 j40 j11
Copper and nickel and purpose: according to the characteristics of low resistance alloy has good resistance to corrosion, good welding performance and machining performance, wide application and thermal overload relays, electrical elements in low-voltage circuit breaker and other low-voltage devices .
