Specific Applications
- Current sensors and measuring equipment: CuNi23 alloy is widely used in current sensors, transformers and other equipment due to its high resistance value and excellent corrosion resistance. In these equipment, CuNi23 alloy can accurately measure current and maintain stable performance, ensuring the safe and efficient operation of the equipment.
- Sensors and resistor cables: CuNi23 alloy is also widely used in aerospace and military fields due to its excellent corrosion resistance and mechanical strength. It is used as a key material for sensors, resistor cables and measuring devices in aerospace equipment. The high requirements for durability and environmental adaptability in military electronic equipment make CuNi23 the preferred material for key components.
- Corrosion-resistant parts: CuNi23 alloy performs well in marine environments and is suitable for manufacturing submarine cables, contact materials in ship electrical systems, etc., ensuring long-term stability in salt spray and seawater. It is not easy to form biological attachments on its surface, which greatly reduces the cost of cleaning and maintenance.
- Marine monitoring equipment: In the marine and chemical industries, due to the strong corrosiveness of the environment, CuNi23 alloy has become an important material for manufacturing key components such as anti-corrosion equipment and pipelines due to its excellent corrosion resistance.
Advantages and Characteristics
- Excellent anti-oxidation and corrosion resistance: CuNi23 alloy can effectively prevent oxidation and corrosion in wet, acidic or alkaline environments, which gives it significant advantages in applications in chemical, electric power, marine and other fields. Even in harsh industrial environments, the alloy can maintain stable resistance performance for a long time, extending the service life of the component.
- Anti-biological fouling ability: In the marine environment, the surface of CuNi23 alloy is not easy to form biological attachment, which greatly reduces the cost of cleaning and maintenance.
- High tensile strength: The yield strength of CuNi23 alloy is usually between 300-450 MPa, and the tensile strength can reach 550-750 MPa, with good ductility and fatigue resistance. The high strength characteristics of the alloy enable it to work stably under complex loading conditions, reducing the risk of equipment damage due to material failure.
- Good hardness and toughness: Due to the addition of nickel, the lattice structure of the alloy has undergone certain changes, enhancing the impact resistance of the metal matrix. Therefore, CuNi23 alloy can still maintain its good structural properties under high-frequency vibration, impact and other working conditions.
