2.Advantage of Tantalum Foil  :


Corrosion resistance: Tantalum foil has excellent corrosion resistance to most common chemicals, including acids, alkalis and salt solutions. This makes tantalum foil ideal for use in corrosive environments such as the chemical industry, electrochemical applications and electrolysis in acidic solutions.


High Melting Point: Tantalum has a very high melting point, about 2996 degrees Celsius. Therefore, tantalum foil can maintain its structural integrity and physical properties in high temperature environments. This makes tantalum foil excellent in high temperature applications such as aerospace, nuclear industry and high temperature reactors.


Excellent conductivity: Tantalum is a good conductive material, and tantalum foil has excellent conductivity, which is higher than many other metals. This makes tantalum foil useful in applications such as electronics, circuits and electrodes.


Biocompatibility: Tantalum foil has good biocompatibility to human tissue, which makes it widely used in the medical field, such as the manufacture of artificial joints, implants and medical devices.


High strength and wear resistance: Although tantalum foil is a thin sheet material, it has good strength and wear resistance. This allows it to function in applications requiring high strength and durability.


3. Application of Tantalum Foil Tantalum Strip:

Chemical industry, Electronic industry, Aerospace industry, Aviation industry, Capacitors, High-temperature furnace parts, Semiconductor, Sputtering targets , Relative devices, And widely applied to electronics, metallurgy, chemical, pharmacy, aerospace and other fields.
