In modern industry, long-term operation of equipment in high-temperature, high-friction, and corrosive environments has become the norm. To ensure the stability and safety of critical components such as cables, hoses, and sensors in these conditions, it is crucial to select a protective material that combines high-temperature resistance with wear resistance. Among these, Ni80Cr20 (80% nickel, 20% chromium) wear-resistant alloy braided sleeves have become a preferred material in many industrial systems due to their superior comprehensive performance.

Ni80Cr20, also known as Nichrome 80/20, is a typical nickel-chromium high-temperature resistant alloy. Composed primarily of 80% nickel and 20% chromium, this material exhibits excellent electrical conductivity, high-temperature oxidation resistance, and good mechanical strength. Due to its dense structure and uniform composition, it is widely used in heating elements, resistance wire, heating cables, and high-temperature protective components.

Ni80Cr20 braided sleeving is constructed from multiple strands of this alloy wire, maintaining the strength of the metal while also providing flexibility and sheathing properties, effectively protecting the cables within from external environmental influences.

The greatest advantage of Ni80Cr20 alloy braided sleeving lies in its exceptional wear resistance. Under conditions of frequent vibration, friction, or contact with rough surfaces, ordinary metal or fiber materials are susceptible to wear and even fracture. However, the tough and high-hardness of the Ni80Cr20 alloy surface significantly prolongs its service life.

Furthermore, this alloy boasts an extremely high operating temperature limit (up to 1200°C), maintaining stable mechanical properties and electrical resistance even in sustained high-temperature environments, and resisting oxidation or deformation. This characteristic makes it ideal for high-temperature applications in industries such as metallurgy, aviation, petrochemicals, heat treatment, and power generation equipment.

The addition of chromium to Ni80Cr20 alloy significantly enhances the density of its surface oxide film, effectively preventing flaking and further corrosion. Furthermore, the presence of nickel ensures the alloy maintains excellent chemical stability in acidic, alkaline, and sulfur-containing atmospheres.
This means that Ni80Cr20 braided tubing maintains excellent resistance to carburization, sulfidation, and corrosion in high-temperature, oxygen-rich, sulfur-containing, or carbon-containing environments.

Ni80Cr20 alloy boasts excellent ductility and weldability, allowing for flexible braiding and customization to suit the shape and size of various equipment. Its smooth surface resists snagging, making it suitable for wrapping cables, sensor wires, hoses, and heating lines.

Furthermore, due to its low temperature coefficient of resistance and high resistivity, it is often used in the manufacture of heating elements or resistors, finding widespread application in electronics, laboratory equipment, and industrial furnaces.

Overall, Ni80Cr20 wear-resistant alloy braided tubing combines high strength, high-temperature stability, corrosion resistance, and abrasion resistance, making it an ideal solution for cable protection in extreme environments. It not only extends equipment life and reduces maintenance costs, but also provides solid protection for industrial automation and high-temperature processes. In the modern industrial system that pursues efficiency and reliability, Ni80Cr20 is gradually becoming a benchmark material in the fields of high-temperature protection and wear resistance, providing strong support for the continuous upgrading of the manufacturing industry.
