Anping Xinye Metal Wire Mesh Products Co., Ltd, based in Hengshui, Hebei, China, is a specialized manufacturer of high-performance metal wire mesh. Our High Toughness Pure Tantalum Support Grid Mesh is engineered specifically for demanding vacuum furnace refractory applications. This mesh combines the exceptional corrosion resistance and high melting point of pure tantalum with superior mechanical toughness, providing reliable structural support in extreme thermal environments. Whether used as a backing screen, diffusion barrier, or heating element support, our tantalum grid mesh delivers consistent performance and long service life.
The product is made from 99.95% pure tantalum wire, ensuring excellent chemical stability and resistance to attack from molten metals, acids, and alkalis. Its high toughness prevents cracking and deformation under thermal cycling, making it ideal for vacuum furnaces operating at temperatures up to 2500°C (under inert atmosphere). The precise woven structure offers uniform open area and optimal gas flow, enhancing heat transfer efficiency and process uniformity.
Below are the key technical specifications of our tantalum support grid mesh:
| Parameter | Value |
|---|---|
| Material Purity | ≥ 99.95% Ta |
| Wire Diameter Range | 0.05 – 0.50 mm |
| Mesh Opening Range | 0.1 – 10 mm |
| Open Area | 30% – 70% (customizable) |
| Maximum Service Temperature | Up to 2500°C (inert atmosphere) |
| Tensile Strength | ≥ 300 MPa (annealed condition) |
| Elongation | ≥ 20% (ensures toughness) |
| Standard Dimensions | Custom sizes up to 1200×1000 mm |
Key Features & Benefits:
- Exceptional High-Temperature Strength: Pure tantalum retains mechanical integrity at temperatures where most metals fail, ensuring reliable support in vacuum furnace hot zones.
- Excellent Corrosion Resistance: Resists attack from aggressive process gases, molten glasses, and metal vapors, reducing contamination and extending mesh life.
- High Toughness & Ductility: The material's inherent toughness prevents brittle fracture during thermal cycling, minimizing downtime and replacement costs.
- Uniform Mesh Structure: Precision woven construction guarantees consistent pore size and open area, enabling predictable gas flow and heat distribution.
- Customizable Specifications: Wire diameter, mesh opening, and sheet dimensions can be tailored to your exact furnace geometry and process requirements.
- Low Outgassing: Suitable for ultra-high vacuum environments; pre-cleaned surface reduces contamination risk.
- Long Service Life: Combined properties of high melting point, chemical inertness, and mechanical toughness result in extended operational cycles.
Common Applications:
- Backing support for refractory insulation layers in vacuum furnaces
- Diffusion barrier screens for sintering and heat treatment processes
- Heating element support grids
- Filter media for molten metal filtration in high-temperature vacuum casting
- Protective shields and baffles in vacuum brazing and annealing

Frequently Asked Questions (FAQ)
-
Q: What is the purity of your tantalum mesh?
A: Our tantalum support grid mesh is made from 99.95% pure tantalum wire, ensuring excellent chemical resistance and high-temperature stability. -
Q: Can the mesh be customized to fit my furnace dimensions?
A: Yes, we offer custom sizes up to 1200×1000 mm, and we can also cut or shape the mesh to your specific requirements. -
Q: What is the maximum operating temperature of this mesh?
A: In an inert atmosphere, pure tantalum mesh can withstand temperatures up to 2500°C. In vacuum, the recommended maximum is around 2000°C to avoid excessive vapor pressure. -
Q: How does the toughness of tantalum compare to other refractory metals like molybdenum or tungsten?
A: Tantalum is more ductile and tougher than molybdenum and tungsten at high temperatures, making it less prone to cracking under thermal cycling. -
Q: Is the mesh surface treated before shipping?
A: Our standard finish is a clean, degreased surface. Electropolishing or other surface treatments are available upon request. -
Q: What is the typical lead time for custom orders?
A: Lead time depends on the quantity and specifications. For standard sizes, it is usually 7–15 working days. Custom specifications may take longer; please inquire. -
Q: Can you provide sample pieces for testing?
A: Yes, we can provide small samples (e.g., 100×100 mm) for evaluation. Please contact us with your requirements. -
Q: Do you offer technical support for selecting the correct mesh?
A: Absolutely. Our engineers can recommend the optimal wire diameter, mesh opening, and weave pattern based on your furnace temperature, pressure, and chemical environment.
