Product Detailed
6J40 constantan films 1.good resistance temperature linear relation; 2.small quantity accepted; 3.fine after-sale services.

6J40 constantan films

Copper has better heat resistance alloy corrosion resistance, good welding properties and processing performance, widely used in thermal overload relays, low-voltage low-voltage circuit breakers and other electrical appliances in the heating element.

The resistance temperature linear relationship of Copper is better than MnCu.

It mainly contains CuNi alloy.
