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

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.
