Nichrome wire mesh, a high-performance alloy mesh crafted by our company, is made from premium nichrome wires—an alloy primarily composed of nickel (60-80%) and chromium (20-40%), with trace elements to optimize properties. This unique composition endows the mesh with exceptional high-temperature resistance, excellent oxidation resistance, and stable electrical resistance, making it a preferred choice for applications requiring reliable heating, filtration, or structural support in extreme thermal environments.
Material Characteristics
- Superior High-Temperature Resistance: Nichrome wire mesh can withstand continuous operating temperatures up to 1100°C, with short-term exposure to temperatures as high as 1200°C. This remarkable heat resistance ensures it remains stable and functional even in the most demanding high-heat settings, outperforming many other metal meshes in thermal durability.
- Excellent Oxidation Resistance: The chromium content in nichrome forms a dense, protective oxide layer on the mesh surface when exposed to high temperatures. This layer prevents further oxidation and scaling, significantly extending the mesh’s service life in environments with air, combustion gases, or other oxidizing agents.
- Stable Electrical Resistance: Nichrome exhibits a high and stable electrical resistance, which makes it ideal for heating applications. When an electric current passes through the mesh, it converts electrical energy into heat efficiently and uniformly, providing consistent heating performance— a key advantage in industrial heating systems and electrical appliances.
- Good Ductility and Workability: Despite its high-temperature properties, nichrome wire remains ductile, allowing for precise weaving into various mesh patterns and sizes. It can be easily shaped, cut, or welded without compromising its structural integrity, enabling customization for specific application needs.
Structural Characteristics
- Uniform and Precise Mesh Construction: Our nichrome wire mesh is produced using advanced weaving techniques, ensuring uniform mesh size, consistent opening distribution, and reliable performance under high temperatures. The tightly interwoven wires form a robust structure that maintains its shape and functionality even after prolonged exposure to heat and thermal cycling.
- High Tensile Strength at Elevated Temperatures: Nichrome wire mesh retains good tensile strength at high temperatures, minimizing deformation or sagging under thermal stress. This structural stability ensures it can withstand mechanical loads and maintain its filtration or heating efficiency in demanding industrial processes.
- Heat-Shock Resistance: The mesh is designed to resist rapid temperature changes (thermal shock), making it suitable for applications where heating and cooling cycles are frequent. It can endure sudden shifts in temperature without cracking or breaking, ensuring long-term reliability.
- Customizable Specifications: To meet diverse industrial requirements, we offer extensive customization options for nichrome wire mesh. This includes varying mesh counts (from fine meshes for precision filtration to coarse meshes for heavy-duty heating), wire diameters, mesh shapes (square, rectangular), and sheet sizes. Our technical team works closely with customers to develop tailored solutions that perfectly align with their specific application needs.

FAQ
What is nichrome wire mesh?
Nichrome wire mesh is woven from a nickel-chromium resistance alloy (Ni 80%, Cr 20%, also called Nichrome 80/20 or Cr20Ni80). It is designed for high-temperature resistance heating, with a stable electrical resistivity and oxidation resistance up to 1200°C.
Is nichrome wire mesh used for heating elements?
Yes. Nichrome is the standard alloy for resistance heating elements because it converts electrical energy into heat efficiently and uniformly. Nichrome wire mesh is used in industrial furnaces, household appliance heating grids and laboratory tube furnaces.
What temperature can nichrome wire mesh withstand?
Nichrome 80/20 wire mesh withstands continuous operating temperatures up to about 1200°C, with a melting point of about 1400°C. Its chromium content forms a protective oxide film that resists scaling at high temperatures.
What is the electrical resistivity of nichrome?
Nichrome 80/20 has an electrical resistivity of about 1.08 µΩ·m (108 µΩ·cm), much higher than stainless steel. This high resistivity is what makes it efficient as a heating element.
What is the difference between nichrome and stainless steel wire mesh?
Nichrome has a high electrical resistivity and is made for heating elements up to 1200°C. Stainless steel has low resistivity and is used for structure and filtration. Choose nichrome for resistance heating; choose stainless steel for corrosion-resistant screening.
What is the difference between Nichrome 80/20 and Cr20Ni80?
They are the same alloy. Nichrome 80/20 (or Ni80Cr20) is the Western designation, while Cr20Ni80 is the Chinese designation — both mean approximately 80% nickel and 20% chromium.
