Overview of ASTM B708 R05200 annealed Tantalum Foil Ta sheets plate tantal strip for lab use

Tantalum (Ta) is a chemical element with the atomic number 73 and is symbolized as Ta on the periodic table. It is a dense, blue-gray, hard, and ductile transition metal. Discovered in 1802 by Anders Gustaf Ekeberg, tantalum is renowned for its high resistance to corrosion and its ability to store and release electrical charges efficiently, making it a critical material in various high-tech applications.

Feature of ASTM B708 R05200 annealed Tantalum Foil Ta sheets plate tantal strip for lab use

  1. Exceptional Corrosion Resistance: Tantalum forms a protective oxide layer that shields the metal from most acids, even at high temperatures, and is virtually impervious to chemical attacks.

  2. High Melting Point: With a melting point of approximately 3,017°C (5,462°F), tantalum ranks among the metals with the highest melting points, enabling its use in extreme temperature environments.

  3. Biocompatibility: Tantalum is well-tolerated by living tissue, making it suitable for biomedical implants such as bone replacements and surgical sutures.

  4. Electrical Conductivity: Although not the best conductor, tantalum has a high capacitance per volume, making it ideal for manufacturing compact capacitors used in electronic devices.

  5. Ductility: It can be drawn into fine wires and fabricated into various shapes without fracturing, a feature that enhances its versatility in manufacturing.

Parameters of ASTM B708 R05200 annealed Tantalum Foil Ta sheets plate tantal strip for lab use

ASTM B708 R05200 annealed Tantalum Foil is a type of metal foil that has undergone a series of heat treatments, includingannealing and heating up to high temperatures.
The specific parameter values for this material may vary depending on the intended application, but some general guidelines can be provided:

* Annealing temperature: The standard annealing temperature for Tantalum foil is typically around 1,600°F (740°C) for a period of at least one hour, followed by a slow cooling phase. This process helps to improve the metal’s strength, durability, and electrical conductivity.
* Heat treatment sequence: The order in which the various heat treatments are performed can affect the final properties of the material. In general, a typical annealing sequence would include heat treatment at a higher temperature and lower rate than the subsequent heating step, such as a rapid cooling phase.
* Annealing time: The duration of each heat treatment can also impact the performance of the material. For example, a shorter Annealing time may result in a more brittle material, while a longer Annealing time may lead to a more ductile material.

It’s important to note that these are just general guidelines, and the specific parameters used for a particular application will depend on factors such as the intended usage of the material, the environmental conditions, and the desired level of performance.
