Tantalum Ta-7.5W Fasteners are specialized corrosion-resistant fasteners manufactured from a tantalum-tungsten alloy containing approximately 7.5% tungsten, with tantalum forming the balance. The addition of tungsten improves the strength and hardness of tantalum while retaining the excellent corrosion resistance associated with tantalum alloys.
We supply Tantalum Grade Ta-7.5W Fasteners in bolts, screws, studs, nuts, washers, threaded rods, and other customized configurations. These fasteners are suitable for demanding chemical-processing and other specialized applications where corrosion resistance, material compatibility, and reliable fastening performance are important.
What Are Tantalum Ta-7.5W Fasteners?
Tantalum Ta-7.5W Fasteners are fasteners manufactured from a tantalum-tungsten alloy containing approximately 7.5% tungsten and balance tantalum. Ta-7.5W combines tantalum's high corrosion resistance with improved mechanical strength and hardness from tungsten. It is used for specialized corrosion-resistant components and fasteners in chemical-processing and other demanding industrial environments.
Ta-7.5W is generally described in technical sources as a Ta-W alloy rather than one of the specific UNS tantalum grades listed in the current ASTM B365 rod-and-wire specification. ASTM B365 currently covers R05200, R05400, R05255, R05252, and R05240.

Ta-7.5W contains approximately 7–8.5% tungsten, with tantalum as the balance in commonly published composition data. The alloy is valued for its combination of corrosion resistance, strength, hardness, and high-temperature capability.
Published technical data identifies Ta-7.5W for corrosion-resistant elastic components and chemical equipment. Other technical references report a density of approximately 16.8 g/cm³ and a melting point around 3025–3030°C, although actual properties can vary with processing condition and product form.

- Higher hardness than commercially pure tantalum
- High melting temperature
- Good high-temperature capability
- Suitable for demanding chemical-processing environments
- Available in customized fastener configurations
- Suitable for specialized corrosion-resistant assemblies

Published Ta-W data supports the alloy's high corrosion resistance and refractory characteristics, while Ta-7.5W-specific sources identify its use in chemical corrosion equipment.
Applications of Tantalum Ta-7.5W Fasteners
ASTM B365 Ta-7.5W Tantalum Fasteners
The phrase ASTM B365 Ta-7.5W Tantalum Fasteners is commonly used commercially to describe Ta-7.5W fasteners made from material supplied in accordance with an ASTM B365-related rod or wire requirement. However, ASTM B365 itself covers tantalum and tantalum-alloy rod and wire, not finished fasteners, and its current scope does not identify Ta-7.5W as a separate UNS grade.
For this reason, we recommend specifying the Ta-7.5W composition, fastener dimensions, manufacturing condition, mechanical requirements, and applicable material documentation in the purchase order.
