Tantalum is a ductile metal. Tantalum has excellent corrosion resistance to most chemicals except hydrofluoric acid. Tantalum metal has a melting point exceeded only by tungsten & rhenium. The melting point of tantalum is approximately 3017 degrees Celsius. Tantalum’s main end uses are in capacitors, vacuum furnaces, chemical process equipment, nuclear reactors, and aircraft parts.
Advanced Refractory Metals is a leading supplier of tantalum products. We offer low pricing and great lead times on all our materials, and we’re capable of supplying custom materials per any specs/drawings you provide us with.
The tolerance of tantalum to interstitial elements and reasonable elastic modulus make it an attractive base element of the alloy. Tantalum is also easy to achieve the inert gas tungsten arc welding (GTA), so it is suitable for the manufacture of various chemical equipment to give play to its corrosion resistance, such as various heat exchangers, […]

Tantalum occurs in columbium ores. As the demand for columbium increases, increasing amounts of tantalum concentrates become available. After a difficult and complex separation and reduction process, both metals are obtained in the form of powder. The powder is pressed in dies to form bars which are vacuum sintered by passing high currents through them […]

Corrosion is the damage or qualitative change of material under the influence of the environment. The corrosion of metal and alloy is mainly caused by chemical or electrochemical damage. Common corrosion-resistant metals are austenitic stainless steel, Hastelloy, Monel alloy, titanium and titanium alloy, platinum, gold, rhodium and other precious metals. Few people know that the […]
