Some key features of CuMn3 include:
It has low electrical resistivity of 12.5 μΩ.Cm at 20°C and a relatively low temperature coefficient of resistance (TCR) ranging from +280 to +380 ppm/K between 20 and 105°C.
The oxide film formed on the surface of CuMn3 provides good oxidation resistance, which can extend the service life of heating elements.
CuMn3 wire exhibits good mechanical properties, with a tensile strength ranging from 290 MPa for larger diameters to higher values for smaller diameters.
The density of CuMn3 is approximately 8.8 g/cm³.
The main components of CuMn3 include copper (about 85%-90%), manganese (2.5%-4%), and the remainder being nickel.
CuMn3 has good processing properties and can be made into various shapes of heating elements by various processing methods.
The low resistivity of the alloy allows for reduced resistance in resistance wire under the same length and cross-sectional area, thereby reducing heating power and increasing efficiency.
These features make CuMn3/NC012/MC012/2.1356 an important material for applications requiring efficient energy transmission, corrosion resistance, and mechanical strength.
Applications:
Due to its high electrical resistivity and low temperature coefficient, CuMn3 is used in the manufacturing of resistor elements, particularly for low-load, low-resistance resistors.
It is used in marine engineering, such as ship piping systems, offshore platforms, and seawater desalination equipment, benefiting from its excellent resistance to seawater corrosion.
CuMn3 is utilized in the chemical industry for equipment that comes into contact with acidic and alkaline media, where it provides long-term stability.
Copper-nickel tubing, including CuMn3, is used in hydraulic and instrumentation systems for marine and offshore applications due to its resistance to saltwater corrosion, ensuring reliable operation.
CuMn3 is used in intercoolers, oil coolers, and honeycomb radiators in the automotive and aerospace industries.
Some automobile manufacturers use CuMn3 for corrosion-resistant tubes in the production of automobile brake lines, and retrofit sets are available for various vehicle types.
CuMn3 is used in condenser tubes, tubes of final heaters, partition walls, and other parts of evaporator plants for fresh water production, especially where seawater is involved.
The alloy is used in vessels, pipes, and fittings for pulps and liquids in pulp and paper production.
CuMn3 is utilized in multi-stage evaporators, feedwater heaters, and processing lines in the food industry.
It is used for gas pipelines, especially for high-pressure oxygen and mobile hydrogen supplies, due to its non-permeability to hydrogen and fatigue strength.
These applications highlight the versatility and importance of CuMn3/NC012/MC012/2.1356 in industries where corrosion resistance, mechanical strength, and electrical properties are critical.
