We are committed to providing quality materials to our customers.
Characteristics of copper-nickel alloy: Pure copper plus nickel can significantly improve strength, corrosion resistance, hardness, electrical resistance and pyroelectricity, and reduce the temperature coefficient of resistivity. Therefore, compared with other copper alloys, white copper has excellent mechanical properties and physical properties, good ductility, high hardness, beautiful color, corrosion resistance and deep drawability.
Uses: Widely used in shipbuilding, petroleum, chemical, construction, electric power, precision instruments, medical equipment, musical instrument production and other departments for corrosion-resistant structural parts. Some white copper also has special electrical properties for making resistive components, thermocouple materials and compensating wires. Non-industrial white copper is mainly used to make decorative crafts.
