Is Tantalum More Strong Than Tungsten?

What is tantalum?

Tantalum, a metallic element, is found mainly in tantalite and is symbiotic with niobium. Tantalum is moderately hard, and ductile and can be drawn into thin foil in the form of filaments. Its coefficient of thermal expansion is very small.

Tantalum has excellent chemical properties and is extremely resistant to corrosion. Although tantalum is highly resistant to corrosion, its corrosion resistance is due to the generation of a stable protective film of tantalum pentoxide (Ta2O5) on the surface. It does not react to hydrochloric acid or concentrated nitric acid, either under cold or hot conditions.

It can be used to make evaporating vessels, etc. It can also be used as electrodes for electronic tubes, rectifiers, and electrolytic capacitors. It is also used in medical treatment to make thin sheets or threads to mend damaged tissues.

An Overview of Ta Element

Chemical symbol Ta, gray metal, in the periodic table belongs to the VB group, atomic number 73, atomic weight 180.9479, body-centered cubic crystal, common chemical compound valence +5.

What is tungsten?

Tungsten (W) is one of the so-called transition metals with the atomic number 74. The shiny gray metal is in a solid state at room temperature.

Tungsten is characterized by special physical and chemical properties:
• Heat resistance: After carbon, tungsten has the highest melting point of all elements at 3422°C. It has a boiling point of around 5,700°C. With these properties, the metal can withstand high temperatures and smelting and in addition, has a very low coefficient of thermal expansion
• Density: 19.3 g/cm³; the density of tungsten is almost as high as that of gold in its pure state.
We prepare our tungsten to perform perfectly in its specific applications. We can determine the following properties through the addition of various alloys
• Machinability (such as cutting processes, formability, weldability)
• Microstructure and recrystallization behavior (recrystallization temperature, embrittlement, aging effects)
• Resistance: Tungsten also has high resistance to acids. Even hydrofluoric acid and aqua regia are hardly able to attack tungsten at room temperature
• Physical properties (such as melting point, vapor pressure, density, electrical conductivity, thermal conductivity, thermal expansion, heat capacity, and electron work function)
• Mechanical properties (such as strength, fracture behavior, creep resistance, and ductility)
• Chemical properties (corrosion resistance)

Is tantalum more strong than tungsten?

Tantalum is highly resistant to scratches and breakage and is extremely durable. Tantalum is therefore resistant to corrosion, and only if exposed to hydrofluoric acid it can corrode.

Unlike metals, such as tungsten, it is also shatterproof. This makes it great for individuals who lead active lives with busy hands.
