Tantalum Sheet Specifications

If thickness exceeds 0.1875", Tantalum Plate is generally the more appropriate product form. If width is below 6", Tantalum Foil or Strip may be more suitable.

Available Tantalum Grades

R05200 Pure Tantalum

R05200 is unalloyed tantalum produced by electron-beam or vacuum-arc melting. It is commonly selected for applications requiring excellent corrosion resistance, ductility, and high-temperature stability.

R05400 Pure Tantalum

R05400 is unalloyed tantalum produced by powder-metallurgy consolidation. It provides the characteristic corrosion resistance and refractory-metal properties of tantalum.

R05252 – Ta-2.5W

R05252 contains approximately 2.5% tungsten. It offers increased strength compared with pure tantalum while maintaining many of tantalum's corrosion and fabrication advantages.

R05255 – Ta-10W

R05255 contains approximately 10% tungsten and provides significantly higher strength than pure tantalum for more demanding structural and high-temperature applications.

R05240 – Ta-40Nb

R05240 contains approximately 40% niobium and is used in specialized applications requiring the combined characteristics of tantalum and niobium.

Tantalum Sheet Applications

Tantalum sheet is used in applications where corrosion resistance, chemical stability, high-temperature capability, or refractory-metal performance is required.

Typical applications include:

• Chemical processing equipment
• Acid-resistant liners and components
• Heat exchangers
• Semiconductor manufacturing equipment
• Vacuum furnace components
• High-temperature furnace parts
• Aerospace and propulsion components
• X-ray and specialized electronic equipment
• Medical and biomedical components
• Laboratory and research equipment
• Fabricated tantalum assemblies
• Corrosion-resistant process equipment

Tantalum Sheet vs. Tantalum Plate vs. Tantalum Foil

Selecting the correct tantalum product form depends mainly on thickness, width, mechanical requirements, and downstream fabrication.

Tantalum Sheet is suitable for general flat-product applications where moderate thickness and larger widths are required.

Tantalum Plate is typically selected for thicker structural or machined components.

Tantalum Foil or Strip is generally more suitable for very thin or narrow applications.
