Product Description

Product Description:

Tantalum mental powder is used to produce a variety of strong, high melting point, alloys. Alloyed with other metals,
tantalum powder is also used to manufacture carbide tools for metalworking equipment and in the production of superalloys.
It is also used in the production of electronic components, such as capacitors and high power resistors. 

Its atomic number is 73. Tantalum is a silvery metal that is soft in its pure form. It is a strong and ductile metal and at
temperatures below 150°C (302°F), this metal is quite immune to chemical attack. It is known to be resistant to corrosion
as it displays an oxide film on its surface.
