Welcome to Anping County Boli Hardware Wiremesh Products Factory — a trusted manufacturer established in 1998 with over two decades of expertise in wire mesh production. Our Tungsten Wire Mesh for Vacuum Furnace Heating Elements is crafted from 99.95% pure tungsten, delivering exceptional thermal stability and durability in extreme environments. Designed specifically for vacuum furnace applications, this mesh ensures uniform heating, excellent oxidation resistance, and long service life, making it an ideal choice for high-temperature industrial processes. With annual export values exceeding US$5 million and shipments to global markets including North America, Europe, and Asia, we are committed to providing reliable, high-performance products that meet the strictest international standards.
Our tungsten wire mesh is manufactured using advanced weaving technology and strict quality control, ensuring consistent mesh opening and wire diameter. The 99.95% purity guarantees minimal impurities, which is critical for maintaining vacuum integrity and preventing contamination of heating elements. Below, we detail the key features, technical specifications, and benefits that make our product a preferred choice for vacuum furnace manufacturers and end-users.
Key Features & Technical Specifications
- High Purity (99.95%) — Minimizes outgassing and contamination in vacuum environments, ensuring stable heating performance.
- Exceptional Thermal Stability — Withstands temperatures up to 3000°C under vacuum, ideal for sintering, brazing, and heat treatment furnaces.
- Uniform Mesh Structure — Plain or twill weave options provide consistent heat distribution, reducing hot spots and extending element life.
- Customizable Dimensions — Available in various mesh sizes (10 to 200 mesh), wire diameters (0.05mm to 0.5mm), widths (1000mm to 1500mm), and lengths per your requirements.
- Excellent Oxidation Resistance — Tungsten’s natural resistance to oxidation at high temperatures minimizes degradation in partial vacuum or inert gas atmospheres.
- Low Vapor Pressure — Essential for maintaining vacuum quality and preventing contamination of furnace components.
- Easy Installation — Flexible yet strong, the mesh can be cut, shaped, and welded to fit various furnace designs.

Frequently Asked Questions
-
Q: What is the maximum operating temperature for this tungsten mesh in a vacuum furnace?
A: Tungsten mesh can operate continuously up to 2400°C under high vacuum (10⁻⁵ Torr or better), and can withstand short-term peaks up to 3000°C. Actual performance depends on furnace atmosphere and design. -
Q: Can I get custom mesh sizes and wire diameters?
A: Yes, we offer full customization for mesh size (10–200 mesh), wire diameter (0.05–0.5 mm), width, and length. Please provide your specifications for a quote. -
Q: How do you ensure the purity of 99.95%?
A: We source high-grade tungsten rods and wires from certified suppliers, and each batch is tested using optical emission spectroscopy (OES) to confirm purity. Test reports are available upon request. -
Q: Is this mesh suitable for use in inert gas atmospheres like argon?
A: Yes, tungsten mesh performs well in argon or other inert gas atmospheres, though oxidation resistance is reduced compared to vacuum. For high-temperature oxidation environments, we recommend molybdenum or TZM alloy mesh. -
Q: What is the typical lead time for orders?
A: For standard mesh sizes, lead time is 10–15 working days. Custom orders may require 20–30 working days depending on complexity. We can expedite for urgent projects. -
Q: Do you provide technical support for installation?
A: Yes, our engineering team can offer guidance on best practices for cutting, shaping, and welding tungsten mesh, as well as recommendations for supporting structures. -
Q: Can you supply samples for testing?
A: Absolutely. We provide free samples (within 300x300mm) for qualified customers. Please contact us with your shipping details and application information. -
Q: What is the minimum order quantity (MOQ)?
A: Standard MOQ is 10 square meters, but we can accommodate smaller quantities for trial orders. Contact us for details.
Note: All product specifications are subject to change without notice. For the most accurate information, please request a product data sheet. We do not claim any certifications beyond those listed on our official documentation. Always consult with our technical team for your specific application.
