Tantalum Alloy

Tantalum Alloy Stockist and Exporter

Shree Sambhav Alloy

Tantalum is one of the rarest elements on earth. It is platinum-gray colored metal and has a density of 16.6 g/cm3 which is twice as dense as steel. Also, it is highly ductile at high temperatures, very hard and has excellent thermal and electrical conductor properties. Its melting point of 2,996°C is the fourth highest of all metals. It is Soft in its pure form.

Tantalum finds use in four areas: high-temperature applications, such as aircraft engines; electrical devices, such as capacitors; sirurgical impants and handling corrosive chemicals. It is rarely used as an alloying agent because it tends to make metals brittle. Tantalum resist corrosion and is almost impervious to chemical attack, for this reason it has been employed in chemical industry, e.g. for heat exchanger in boilers where strong acids are vaporized.

Available Forms :Rods, Bars, Plates, Flat, Sheets, Etc.
