FAQs

Q1 How are Tantalum Tungsten Foil and Strip manufactured?
Tantalum Tungsten foil and strip are manufactured through a detailed process:

Powder Blending: Tantalum and tungsten powders are mixed in precise ratios, such as Ta2.5W (97.5% Tantalum, 2.5% Tungsten) or Ta10W (90% Tantalum, 10% Tungsten).
Compression and Sintering: The powder blend is compressed into billets and sintered in a vacuum furnace at high temperatures to achieve a homogenous alloy.
Rolling Process: The sintered billets are rolled into thin foils or strips through multiple passes, with periodic annealing to reduce stress and maintain ductility.
Final Finishing: The surface is cleaned, polished, or coated as required, ensuring uniform thickness and surface quality.

Q2. How do I choose between Ta2.5W and Ta10W?

Ta2.5W (97.5% Tantalum, 2.5% Tungsten):

Offers higher ductility and easier machinability.
Best for applications requiring forming, bending, or shaping, such as medical devices and intricate components.
Maintains excellent corrosion resistance.

Ta10W (90% Tantalum, 10% Tungsten):

Provides superior strength and wear resistance.
Ideal for high-stress or high-temperature environments, such as aerospace or chemical processing.
Offers enhanced resistance to creep deformation at elevated temperatures.

When deciding, consider whether ductility or strength is the priority for your application.

Q3. What are the advantages of Tantalum Tungsten Foil and Strip?

High Corrosion Resistance: Excellent performance in highly acidic and reactive environments.
Heat Resistance: Suitable for applications requiring stability at temperatures above 2000°C.
Strength and Durability: Tungsten enhances mechanical strength and wear resistance.
