Tantalum is a refractory metal, falling between tungsten and molybdenum in terms of melting point (5425 F). It is widely available in EB cast and powder metallurgy mill forms. Tantalum is best known for its unmatched corrosion resistance and chemical inertness. Tantalum has a similar corrosion resistance to that of glass, but all of the typical mechanical and electrical properties of a metal. Tantalum is also extremely stable at high temperatures, since tantalum has a melting point around 3000°C. High temperature applications require vacuum or inert gas since tantalum may embrittle when used in oxygen rich environments above 250°C. Tantalum is also one of the most bio-compatible metals available and is also radio-opaque.
Tantalum Fasteners Applications - They fall into two major categories: electronic and metallurgical. The electronics industry is the largest single user, where it is employed in capacitors, filaments and various other high temperature components. The chemical process equipment industry commonly employs tantalum in heat exchangers, heaters, vessels, etc. Tantalum is also used to produce a variety of alloys that have high melting points, strength, and ductility. It is also occasionally used in precious watches e.g. from Audemars Piguet, Hublot, Montblanc, Omega and Panerai.
