Tantalum Bolt & Fastener can provide custom tantalum fastener solutions for your unique tantalum bolt, tantalum nut & tantalum screw applications. Just let us know the requirements of your tantalum fasteners and our engineering staff will help guide you to the best solution for your tantalum fastener application. Metal King tantalum fasteners are optimized concerning chemical and mechical performance. Metal King fasteners offer the full corrosion resitance of Tantalum, but are mechanically improved due to their steel core and Tantaline's patented alloy bonding technology. Metal King tantalum fasteners offer a corrosion performance that is well beyond that of titanium or other Speciality metals like zirconium or Hastalloy.
Tantalum fasteners are also extremely stable at high temperatures, since its melting point around 3000C. Furthermore, tantalum fasteners are also one of the most bio-compatible metals around and because of is high density (16.68 g/cm3) its radio-opaque. Physical Properties
All tantalum fasteners are available in commercially pure tantalum, tantalum 2.5% tungsten (Ta-2.5%W) and tantalum 10% tungsten (Ta-10%W).
