Copper Nickel Alloy Wire with 10-30% Nickel Content and 0.48 Resistivity for Resistor Components with Hydrogen Annealed Surface

Product Description:

The Copper Nickel Alloy Wire is a high-quality product manufactured in Shanghai, China, known for its exceptional performance and durability in various industrial applications. This alloy wire, commonly referred to as CuNi 2 wire, CuNi resistance wire, or CuNi 19 wire, is designed to meet stringent standards required for resistance and thermal management components. Its unique composition and specialized surface treatment make it an ideal choice for applications demanding reliability and efficiency under demanding conditions.

One of the defining characteristics of this Copper Nickel Alloy Wire is its excellent resistivity, measured at 0.48 ohm·mm²/m. This property ensures that the wire performs effectively as a resistance element, providing stable and predictable electrical resistance. As a CuNi resistance wire, it is widely used in heating elements, thermocouples, and precision resistors where consistent resistance values are crucial for accurate temperature control and electrical performance.

The wire’s thermal conductivity is less than -6 W/m·K, which indicates its low thermal conductivity characteristics. This makes the CuNi 2 wire particularly suitable for applications where minimal heat transfer is desired. The ability to resist heat flow is essential in environments where maintaining specific temperature gradients is critical, such as in temperature sensors or heating components that require precise thermal regulation.

This Copper Nickel Alloy Wire is available in various temperature ratings, ranging from 130°C to 240°C, including specific ratings at 130, 155, 180, 200, 220, and 240 degrees Celsius. This wide temperature range allows it to be utilized in diverse applications, from moderate to relatively high-temperature environments without compromising its mechanical or electrical properties. Whether used in marine engineering, aerospace, or electrical heating systems, the CuNi 19 wire offers versatility and reliability across different temperature requirements.

Another significant feature of this product is its surface treatment, which involves hydrogen annealing. This process enhances the wire’s surface quality by reducing oxides and impurities, resulting in improved ductility and corrosion resistance. Hydrogen annealing also stabilizes the wire’s microstructure, ensuring consistent performance during extended use. The treated surface facilitates easier handling and better solderability, which is particularly important in manufacturing processes where precision and reliability are paramount.

Originating from Shanghai, China, this Copper Nickel Alloy Wire benefits from advanced manufacturing techniques and stringent quality control measures. The production facilities in Shanghai are equipped with state-of-the-art technology that guarantees the wire meets international standards for composition, dimensional accuracy, and performance. Customers can trust that each batch of CuNi resistance wire maintains high consistency, ensuring dependable results in their applications.

In summary, the Copper Nickel Alloy Wire, including the CuNi 2 wire and CuNi 19 wire variants, offers a combination of low thermal conductivity, stable resistivity, and excellent surface properties due to hydrogen annealing. Its adaptability to a wide temperature range and origin from a reputable manufacturing hub in Shanghai, China, makes it a preferred choice for industries requiring reliable resistance wire solutions. Whether for heating elements, temperature sensors, or other specialized electrical components, this CuNi resistance wire stands out as a durable and efficient material that meets the demanding needs of modern technology.
