1. What is Tantalum Wire Mesh?

Tantalum Wire Mesh is a woven mesh manufactured from tantalum wire. It combines the mechanical structure of a precision mesh with tantalum's exceptional corrosion resistance and high-temperature capability.

2. Why is tantalum used for wire mesh?

Tantalum is highly resistant to chemical attack and performs exceptionally well in many aggressive environments. This makes tantalum mesh useful where conventional stainless steel, nickel, or other alloys may not provide sufficient corrosion resistance.

3. What mesh sizes are available?

REG Metals can supply a broad range of mesh counts, including fine and coarse mesh configurations, with custom mesh counts and opening sizes available.

4. What weave patterns are available?

Common configurations include:

• Plain weave
• Twill weave
• Custom woven configurations

The appropriate weave depends on the required opening size, strength, and application.

5. Can Tantalum Wire Mesh withstand high temperatures?

Yes. Tantalum has a melting point of approximately 3,020°C, making it suitable for many high-temperature applications. Actual service temperature depends on the environment, particularly the presence of oxygen and other reactive gases.

6. Is Tantalum Wire Mesh corrosion resistant?

Yes. Tantalum is exceptionally resistant to corrosion and chemical attack in many aggressive chemical environments.
