- Immune to numerous acids and chemicals (corrosion tables)
- Better corrosion resistance than nickel alloys, titanium or zirconium
- High strength and stiffness in vacuum and inert gas up to 2000°C (3600°F)
- Can become brittle when used in oxygen above 300°C
- High purity and biocompatibilty
- Physical Properties
Tantalum fasteners are best known for its unmatched corrosion resistance and chemical inertness. Tantalum fasteners have a similar corrosion resistance to that of glass, but all of the typical mechanical and electrical properties of a metal.
Tantalum fasteners are also extremely stable at high temperatures, since tantalum has a melting point around 3000°C. High temperature applications require vaccum or inert gas since tantalum may embrittle when used in oxygen rich environments above 250°C. Tantalum fasteners are also one of the most bio-compatible metals available and is also radio-opaque due to its high density (16.68 g/cm3).
All tantalum fasteners are available in commercially pure tantalum and tantalum 2.5% tungsten (Ta-2.5%W).

Tantalum Fastener Types: Bolts, Nuts, Screws, Threaded Rods, Washers
Common Tantalum Fastener Grades
Tantalum (Commercially Pure)
Commercially pure tantalum metal is 99.95% pure tantalum has some o the best corrosion resistant properties of any metal. While its corrosion resistance is exceptional, it is relatively soft and mechanically similar in strength to copper.
Tantalum 2.5% Tungsten (Ta-2.5W)
This grade of tantalum alloyed with 2.5% tungsten provided better overall strength while maintaining its exception corrosion resistant properties. For tantalum fastener applications this is usually preferred.
