Technical tantalum

Technical tantalum contains about 97% Ta and up to 2.5% tungsten. Such metal is used where high corrosion resistance and deformability (including at low temperatures) are important. The alloy is also higher in strength than chemically pure tantalum while retaining good machinability characteristics.

Alloy of tantalum and tungsten

This alloy, containing 90% Ta and 10% W/, is used in high-temperature devices and assemblies where increased corrosion resistance is required. The tensile strength is doubled compared to pure tantalum.

Applications

Electronics manufacturing, mainly capacitors. Tantalum is difficult to replace in cellular phones, personal computers and automotive electronics. The metal is part of the materials for the manufacture of carbide tools, metal cutting tools, as well as the production of parts for jet engines.
