Other characteristics of tantalum
In commonly used metal contains about 97% tantalum and up to 2.5% tungsten. This metal is used in cases where high corrosion resistance and deformability (including at low temperatures). This alloy is also higher in strength than pure tantalum while maintaining the good characteristics of workability.
Practical application is also of an alloy containing 90 percent tantalum and 10% tungsten.
This alloy is used in high temperature devices and components that require improved corrosion resistance. Tensile strength, compared with pure metal, doubled.
Tantalum (TA) is ductile, easily manufactured, has a high resistance to corrosion by acids and a good conductor of heat and electricity and has high melting point. The main use of tantalum is in the manufacture of electronic components, mainly capacitors. Main purpose of the use of tantalum elements — case of mobile phones, personal computers and automobile electronics. Tantalum is also used to make carbide tools for Metalworking and the production of hard alloys for machining of jet engines.
