Product Description

Ualloy 35-CuNi30 Copper Nickel Low Resistance Alloy Plate

1. Description

Ualloy35 is a copper-nickel alloy (Cu70Ni30 alloy) with low resistivity for use at temperatures up to 350°C.
Ualloy35 is kind of low resistance heating alloy.It is one of the key materials of the low-voltage electrical products. It is
widely used in low-voltage circuit breaker, electric blankets.thermal overload relay, and other low-voltage electrical product.
Ualloy35 is typically used for low-temperature applications such as heating cables.
