Chapter 1

What is Tantalum? Why It's Special?

Tantalum, primarily used in the forms of sheets, foils, and plates, is a critical material in various industrial applications due to its unique properties. Here we dive deep into these properties, providing detailed insights that highlight why tantalum is so valuable in today’s high-tech and high-stress environments.

Physical Properties

  1. High Melting Point: Tantalum has an exceptionally high melting point of about 3,017°C (5,463°F), making it perfect for use in high-temperature applications where lesser metals would melt or degrade. This property is essential for its use in aerospace and power generation industries.
  2. Density: It has a high density of 16.65 g/cm³, comparable to that of uranium and gold. This high density makes tantalum sheets and plates particularly robust and durable, ideal for producing heavy-duty parts with relatively compact dimensions.
  3. Ductility: Tantalum is highly ductile, allowing it to be drawn into fine wires or stretched into thin foils without fracturing. This ductility facilitates the manufacturing of tantalum foils used in capacitors and other electronic components.

Mechanical Properties

  1. Tensile Strength: The tensile strength of pure tantalum is about 180 MPa, but this can increase significantly when alloyed with other metals like tungsten or niobium. Tantalum alloys are engineered to possess tensile strengths as high as 1,000 MPa, making them suitable for extreme applications.
  2. Hardness: On the Mohs scale of mineral hardness, tantalum scores between 6 and 6.5, which makes it comparable to titanium and softer than popular hard metals like tungsten. However, its Vickers hardness can be about 200 HV, indicating its suitability in wear-resistant applications.
  3. Elastic Modulus: The elastic modulus of tantalum is about 186 GPa, which is lower than that of many steels but still indicates good rigidity and resistance to deformation under stress.

Chemical Properties

  1. Corrosion Resistance: One of Tantalum’s most remarkable features is its excellent resistance to corrosion; it does not react with hydrochloric acid, concentrated nitric acid, or even aqua regia under normal conditions. This resistance makes it ideal for chemical reaction vessels, heat exchangers, and other equipment exposed to aggressive environments.
  2. Reactivity: At room temperature, tantalum is almost completely inert to chemical attack. This property makes it very useful in applications where high purity is necessary, such as semiconductor production and laboratory equipment.

Thermal Properties

  1. Thermal Conductivity: Tantalum has a thermal conductivity of 54 W/mK, which is lower than that of copper but higher than that of stainless steel. This moderate level of thermal conductivity means that it can effectively dissipate heat in applications like electronic heatsinks.

Coefficient of Thermal Expansion: Its coefficient of thermal expansion is relatively low (6.3 × 10^-6 per °C), which ensures that it remains stable under conditions of thermal cycling. This stability is crucial for applications in aerospace and electronics, where materials must maintain their shape and size despite drastic temperature changes.

It is characterized by its high ductility, making it ideal for processing into various forms like sheets, foils, and plates. It is commonly used in chemical processing equipment due to its excellent corrosion resistance.
  • R05400: Similar to R05200, this grade also features unalloyed tantalum but with slightly different mechanical properties tailored for different applications. It maintains the same high corrosion resistance and is suitable for both aerospace and medical applications.
  • R05255 (Tantalum Tungsten Alloy, Ta-10W): This alloy contains 10% tungsten and 90% tantalum, offering increased hardness and higher melting point, which makes it suitable for high-temperature applications in aerospace and military engineering.

R05252 (Tantalum Niobium Alloy, Ta-40Nb): Comprising 60% tantalum and 40% niobium, this alloy is highly resistant to corrosion and has superior mechanical properties at high temperatures, making it ideal for use in nuclear reactors and other high-stress environments.

Chapter 4

Production Standard of Tantalum Sheet, Foil and Plate

Production Standards

The production of tantalum sheets, foils, and plates is regulated by several standards to ensure quality and consistency:

  • ASTM B708: This is the primary standard for the manufacture of flat tantalum products, including sheets and plates. It specifies requirements for the mechanical properties, dimensions, and tolerances of tantalum products, ensuring they are suitable for industrial applications. The standard helps manufacturers produce consistently high-quality sheets and plates, which are crucial for applications requiring a high degree of precision and reliability.
  • ASTM F560: A standard specifically for medical-grade tantalum used in surgical implants. It ensures that the material is biocompatible and safe for human implantation.
