Product Description
Technical details, material information and manufacturing notes for this product.
Tantalum Plate / Sheet Overview
Tantalum plates and sheets are premium flat-rolled refractory metal products.
They are manufactured from pure tantalum or tantalum alloys.
They offer excellent corrosion resistance, ductility, and thermal stability.
Tantalum is known as a noble refractory metal.
It resists acids that can dissolve platinum.
It also provides outstanding formability at room temperature.
1. Dimensional Standards (ASTM B708)
Flat tantalum products are classified under ASTM B708 standard.
Tantalum Foil / Strip
Thickness below 0.13 mm.
Usually supplied in coil form for precision applications.
Tantalum Sheet
Thickness from 0.13 mm to 4.75 mm.
Used in industrial fabrication and chemical equipment.
Tantalum Plate
Thickness above 4.75 mm.
Used for heavy-duty structural and machining applications.
2. Key Material Properties
Corrosion Resistance
Tantalum forms a stable oxide layer (Ta2O5).
It resists hydrochloric, nitric, and sulfuric acids.
Only hydrofluoric acid can attack it effectively.
Excellent Ductility
Tantalum can be cold formed without cracking.
It is suitable for stamping, bending, and deep drawing.
High Melting Point
Tantalum has a melting point of 2,996°C.
It remains stable in vacuum and high-temperature environments.
3. Common Grades (UNS Standard)
