Copper Based Nickel CuNi10 NC015 Rod Strip Wire Heating Resistance
Material
The addition of nickel to pure copper can significantly improve the
strength, corrosion resistance, hardness, electrical resistance and
thermoelectricity, and reduce the temperature coefficient of
resistivity. Therefore, compared with other copper alloys, the
mechanical and physical properties of cupronickel are extremely
good, with good ductility, high hardness, beautiful color,
corrosion resistance and deep drawing performance.
It is widely used as corrosion-resistant structural parts in
shipbuilding, petroleum, chemical, construction, electric power,
precision instruments, medical equipment, musical instruments and
other departments. Some cupronickel has special electrical
properties, which can be used to make resistance elements,
thermocouple materials and compensation wires. Non-industrial
cupronickel is mainly used to make decorative crafts.
The ductility of copper-nickel alloy is very good, so it can be
used in shipbuilding and petrochemical industry. Some electrical
appliances and meters also use the ductility of copper-nickel
alloys to manufacture parts. Copper-nickel alloys are mostly used
in industrial production. Some valves and some precision resistance
parts will be made of copper-nickel alloys.
