TA0002 Tantalum Foil/Strip
Tantalum foil/strip is a thin, flexible sheet made from pure tantalum or tantalum alloys, known for its exceptional corrosion resistance, high melting point, and biocompatibility.
Descriptions of Tantalum Foil/Strip
Tantalum (Ta) is a dark blue-gray metal that is very heavy, ductile and hard and has high corrosion resistance. Tantalum is especially resistant to chemicals at temperatures below 150 °C and can only be dissolved with hydrofluoric acid. It has the fourth highest melting point of all metals and is able to form extremely thin and protective oxide layers for high-quality capacitors, making it an excellent material for foil.
Specifications of Tantalum Foil/Strip
| Product Name | Thickness (mm) | Width (mm) | Length (mm) | Material | Standard | Purity |
| Tantalum Foil | 0.03-0.07 | 30-200 | >50 | UNS R05200, UNS R05400 | ASTM B708-98 | ≥99.95% or 99.99% |
| Tantalum Strip | 0.03 | 1-1.5 | Up to 50000 | UNS R05200, UNS R05400 | ASTM B708-98 | ≥99.95% or 99.99% |
Key Properties of Tantalum Foil/Strip:
-
Corrosion-Resistant – Resists almost all acids (except HF/hot H₂SO₄).
-
High-Temperature Stable – Melts at ~3,020°C; ideal for extreme heat.
-
Biocompatible – Safe for medical implants (e.g., bone repairs).
-
Flexible & Thin – Rollable to 0.01 mm thickness.
-
Electrically Functional – Forms stable Ta₂O₅ for capacitors.
Applications of Tantalum Foil/Strip
• Tantalum foil/strip is essential for manufacturing high-performance capacitors and sputtering targets in the electronics industry.
• In the chemical industry, tantalum foil/strip provides corrosion-resistant linings for reactors and heat exchangers.
• The medical field utilizes tantalum foil/strip for implants and radiopaque markers due to its biocompatibility.
• Tantalum foil/strip serves critical functions in aerospace applications, including rocket nozzle components and radiation shielding.
• Tantalum foil/strip finds additional use in vacuum furnace components where high-temperature stability is required.
• For semiconductor manufacturing, tantalum foil/strip is employed as diffusion barrier layers in microchips.
