Tantalum profile

Tantalum (Ta) has the features of ductile, easily fabricated, highly resistant to distortion by high temperature and corrosion by strong acids, and a good conductor of heat and electricity and has a high melting point. The major use for tantalum, as tantalum metal powder, is in the production of electronic components, mainly tantalum capacitors. Major end uses for tantalum capacitors include portable telephones, pagers, personal computers, and automotive electronics. Alloyed with other metals, tantalum is also used in making carbide tools for metalworking equipment and in the production of super alloys for jet engine components.
SinoDevices have the following Tantalum products:
Capacitor Grade Tantalum Wire
Tantalum Furnace Parts
Tantalum Crucible / Tray
Tantalum fittings / fasteners
Tantalum bar
Tantalum Alloy Tubing
Tantalum alloy plate / strip
Tantalum metal has for decades been acknowledged as the metal with the highest corrosion in hot acids. In most acidic media no significant corrosion rates of tantalum can be measured. We supply premium grade tantalum parts and we have solved many of the problems typically are involved when working in tantalum.

Tantalum Furnace Parts

Tantalum is highly resistant to distortion by high temperature,  therefore it is widely used for high-temperature applications, such as sintering, sputtering, melting of refractory, rare and noble metals, to be heating elements, shield and Tantalum Furnace Parts.

  Tantalum Furnace

We can make the Tantalum Furnace Parts by customized.


Tantalum Crucible / Tray

Tantalum crucible (tray) is widely used in sintering of capacitor anode, sputtering equipment, melting of refractory, rare and noble metals.

Tantalum Crucible Tray

We can make the Tantalum Crucible / Tray by customized.


Tantalum fittings / fasteners

Tantalum fittings / fasteners are optimized concerning chemical and mechanical performance. Due to its melting point of 2996, density of 16.68g/cm3, heat transfer coefficient of 54W/M.K @ 25,  high conduction, high heat stability and high anti-corrosion, tantalum has versatile functions in many mechanical manufacturing applications.

SinoDevices Tantalum offers the advantage of:

Enhanced Mechanical Stability
Composed with a pure c.p. tantalum surface supported by strong steel based core, the tantalum components  are mechanically more stable than solid c.p. tantalum. 

Overcomed the Hydrogen Embrittlement phenomena, more safe
Our tantalum is supported by core that is not sensitive to hydrogen embrittlement, it is safe in situations where normal tantalum components will fail due to hydrogen embrittlement. 

Cost efficient production of using tantalum components
Due to our highly efficient production procedures we can offer tantalum products with most competitive price.
