Anping County Boli Hardware Wiremesh Products Factory has been a trusted manufacturer of high-quality wire mesh since 1998. Our Tungsten Wire Mesh for Vacuum Furnace Heating Elements is engineered to meet the demanding requirements of high-temperature industrial applications. Featuring a 0.2mm wire diameter and a 50x50 mesh count, this product delivers excellent electrical conductivity, uniform heat distribution, and outstanding durability in vacuum environments. With annual export values reaching US$5-10 million and shipments to over 15 major markets worldwide, our tungsten mesh is the preferred choice for furnace builders and replacement parts suppliers.
Product Overview: This tungsten wire mesh is specifically designed for use as heating elements in vacuum furnaces. The 0.2mm thin wire allows for rapid heating and precise temperature control, while the 50x50 mesh provides a balanced combination of structural strength and open area. Manufactured from high-purity tungsten (99.95% min), it offers excellent resistance to thermal shock, oxidation, and creep at elevated temperatures, ensuring long service life even in cyclic heating conditions.
Key Features & Benefits
- High Purity Tungsten: 99.95% pure tungsten ensures optimal electrical and thermal performance, minimizing contamination in vacuum environments.
- Precise Wire Diameter: 0.2mm wire size offers low resistance and uniform heating across the entire mesh surface.
- 50x50 Mesh Count: Provides adequate mechanical support while allowing efficient heat dissipation and gas flow.
- Plain Weave Construction: Stable structure with consistent opening size, reducing hot spots and extending element life.
- Excellent High-Temperature Resistance: Operates reliably up to 3000°C (5432°F) in inert or vacuum conditions.
- Customizable Dimensions: Available in various widths and lengths; cut-to-size options available upon request.
- Corrosion & Oxidation Resistance: Suitable for use in reducing atmospheres and high-purity vacuum furnaces.

Frequently Asked Questions
-
Q: What types of vacuum furnaces are suitable for this tungsten mesh?
A: This mesh is ideal for high-temperature vacuum furnaces used in sintering, brazing, annealing, and heat treatment of advanced materials. It works well in both hot-zone and heating element configurations. -
Q: Can the mesh be cut to specific dimensions?
A: Yes, we offer custom cutting to your required width and length. Please provide your exact specifications when ordering, and we will prepare the mesh accordingly. -
Q: What is the maximum operating temperature in a vacuum?
A: The tungsten mesh can withstand temperatures up to 3000°C (5432°F) in high vacuum or inert gas atmospheres. However, actual performance depends on furnace design and heating rate. -
Q: How does the 0.2mm wire diameter affect heating performance?
A: The 0.2mm wire offers a higher surface-to-volume ratio, leading to faster heat-up and more uniform temperature distribution. It also reduces overall mass, which is beneficial for rapid thermal cycling. -
Q: Is the mesh resistant to oxidation?
A: Tungsten oxidizes rapidly above 500°C in air. Therefore, this mesh is designed for use in vacuum or inert/reducing atmospheres. It is not recommended for oxidizing environments. -
Q: What is the typical lifespan of this heater mesh?
A: Lifespan varies with operating conditions, but with proper handling and controlled heating cycles, our tungsten mesh can last thousands of hours. The 50x50 mesh design provides good mechanical stability, reducing sagging and deformation. -
Q: Can you provide samples for testing?
A: Yes, we offer sample rolls of small size (e.g., 100mm x 100mm) for evaluation. Please contact our sales team to discuss sample availability and shipping costs. -
Q: What are the packaging and shipping options?
A: The mesh is carefully rolled with protective layers and packed in sturdy cartons or wooden crates. We ship from Tianjin, Qingdao, Shanghai, and Foshan ports. Express delivery (DHL, FedEx) is available for urgent orders.
