Density, hardness and specific heat of tantalum and tantalum alloys

Are you interested in the physical and mechanical properties of tantalum from the supplier company AvecGlob? Here you will find interesting information on this topic.

General information

Tantalum (Ta) is a heavy (at least 16400 kg / m ³) metal of blue-gray color with a melting point of 2996 ° C. It has excellent corrosion resistance, good ductility and is resistant to most acids.

Tantalum has many positive physical properties — in electronics it forms the basis of high-performance capacitors used in electrical products, and when alloyed with iron provides excellent corrosion resistance. Tantalum is used in aggressive environments, such as oil and gas pipelines. In aluminum alloys, it prevents oxidation by allowing lighter components to be used safely and, thanks to its high melting point, is also used to cement tungsten carbide in machines and in alloys found in turbine blades of jet engines.

Particular interest in tantalum is due to its increasing use in capacitors in electronic equipment. The advantage of tantalum in capacitors is its high volume efficiency, which provides miniaturization, high reliability and stability over a wide temperature range (-55 ° C to 125 ° C) that do not correspond to other types of capacitor material, for example ceramics.

Alloys containing tantalum (percentage of 2 to 12%) are used in aircraft engines and in turbines used in the production of electricity.
