NiCr Resistance Wire - Premium Cr20Ni80 & Cr30Ni70 for Industrial Heating Elements

Products Description

Our premium NiCr resistance wires, Cr20Ni80 and Cr30Ni70, are engineered for high-performance industrial heating applications. These NiCr resistance wires, including Cr20Ni80 and Cr30Ni70, are known for their exceptional heat resistance up to 1200°C for Cr20Ni80 and 1250°C for Cr30Ni70, making them ideal for demanding environments such as furnaces, kilns, and industrial ovens. With excellent oxidation resistance and high tensile strength, these NiCr resistance wires ensure reliable and consistent performance.

Cr20Ni80 (80% nickel, 20% chromium) and Cr30Ni70 (70% nickel, 30% chromium) offer a perfect balance of durability, corrosion resistance, and cost-effectiveness in NiCr resistance wire applications. Their stable electrical resistivity ensures uniform heating, making these NiCr resistance wires, Cr20Ni80 and Cr30Ni70, a top choice for industries like metal processing, glass manufacturing, and aerospace.

Products Specification

With a tensile strength of about 650 MPa, Cr20Ni80 is tough enough to last for years, cutting down on maintenance and replacements. It’s also super versatile—we can shape it into coils, strips, or custom heating elements to fit any industrial setup. That kind of flexibility is a big deal for manufacturers needing tailored solutions.

Key Features

• High-Temperature Resistance

  The NiCr resistance wire, specifically Cr20Ni80 and Cr30Ni70, operates reliably up to 1200°C for Cr20Ni80 and 1250°C for Cr30Ni70, allowing them to withstand extreme heat conditions in industrial settings without degrading performance. This high-temperature capability in NiCr resistance wire ensures that heating elements remain functional over prolonged periods, reducing the risk of failure and enhancing overall system efficiency in applications where consistent heat is critical.

• Oxidation Resistance

  These NiCr resistance wires, Cr20Ni80 and Cr30Ni70, form a protective oxide layer that effectively withstands corrosive atmospheres, preventing material breakdown and extending the lifespan of the wire in harsh environments. This feature of NiCr resistance wire is particularly beneficial in oxidizing conditions, where it maintains structural integrity and resists scaling, ensuring long-term reliability and minimal maintenance for industrial heating systems using Cr20Ni80 or Cr30Ni70.

• High Tensile Strength

  With approximately 650 MPa for Cr20Ni80 and 700 MPa for Cr30Ni70, this NiCr resistance wire provides exceptional mechanical strength, enabling it to endure physical stresses and vibrations common in industrial operations. The robust tensile properties of NiCr resistance wire like Cr20Ni80 and Cr30Ni70 contribute to durability, allowing for repeated thermal cycling without fracturing, which ultimately lowers replacement frequency and operational costs in demanding heating applications.

• Versatility

  Available in coils, strips, or custom shapes, the NiCr resistance wire, including Cr20Ni80 and Cr30Ni70, offers flexibility for tailored heating solutions that can be adapted to various industrial setups and specific design requirements. This versatility in NiCr resistance wire makes Cr20Ni80 and Cr30Ni70 suitable for a wide array of configurations, from intricate heating coils to large-scale elements, providing manufacturers with the adaptability needed to optimize performance across diverse applications.

• Stable Resistivity

  The consistent electrical performance of NiCr resistance wire, with stable resistivity in Cr20Ni80 and Cr30Ni70, ensures precise heating control and uniform temperature distribution across the heating element. This stability in NiCr resistance wire prevents fluctuations that could lead to uneven heating, thereby improving process accuracy and product quality in industrial applications where Cr20Ni80 or Cr30Ni70 are employed for critical thermal management.
