Tantalum R05252 Fasteners are made from a tantalum-tungsten alloy containing approximately 97.5% tantalum and 2.5% tungsten by nominal designation. Also known as Ta-2.5W Fasteners, UNS R05252 is a refractory-metal alloy valued for its corrosion resistance and improved strength compared with unalloyed tantalum. ASTM B365 covers R05252 tantalum alloy rod and wire, while other ASTM specifications cover R05252 in forms such as plate, sheet and tube.

Tantalum R05252 Ta-2.5W Fasteners Bolts Screws
Tantalum R05252 Fasteners are specialized fastening components manufactured from Ta-2.5W, a tantalum alloy strengthened with tungsten. The UNS R05252 designation identifies a tantalum alloy containing nominally 2.5% tungsten, with tantalum making up the balance. ASTM identifies R05252 as a 97.5% tantalum–2.5% tungsten alloy produced from vacuum-arc or electron-beam melted material.
We supply Tantalum Grade R05252 Fasteners in different configurations for industrial assemblies where corrosion resistance, material purity and specialized alloy performance are important.
Our range can include Ta-2.5W bolts, UNS R05252 tantalum screws, socket head cap screws, stud bolts, nuts, washers and threaded rods. Products can be manufactured or supplied according to specified dimensions, thread requirements, drawings and applicable material documentation.
The alloy is also identified by names such as Tantalum 2.5 Tungsten Alloy, Ta-2.5W Alloy and UNS R05252 Tantalum Alloy.

ASTM B365 R05252 Tantalum Fasteners
ASTM B365 is important when specifying the raw material for R05252 components. The standard covers tantalum and tantalum-alloy rod and wire and explicitly includes R05252. It requires chemical analysis and specified mechanical properties for the covered material.
Therefore, for a fastener purchase, it is preferable to specify requirements such as:
- UNS R05252
- Ta-2.5W composition
- ASTM B365 material requirement where applicable
- Fastener dimensions
- Thread specification
- Product configuration
- Quantity
- Testing requirements
- MTC requirements
- Drawing/specification number
This approach makes the material and finished-product requirements clearer.
Advantages of Tantalum R05252 Fasteners
Applications of Tantalum R05252 Fasteners
Tantalum R05252 Fasteners can be used in specialized applications involving aggressive chemical environments and demanding material requirements.
Typical areas include:
- Chemical processing equipment

- Heat-exchanger components
- Reaction equipment
- Laboratory equipment
- Specialized industrial machinery
- High-temperature processing systems
- Acid-processing equipment
- Refractory-metal assemblies
The correct fastener grade should be selected based on the actual process environment rather than corrosion resistance alone.
