CuNi1 alloy wires(NC003)
the characteristics of product: small resistance temperature coefficient; good stability;
high mechanical strength.
It can be used into circuit breakers,thermal overload relay.
It is one of the key materials in the low-voltage electrical products.
My company can provide good products.
Pass:ISO9001:2008 certification, DIN17471-1981 standard
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.
