Tantalum wire is a valuable and versatile material made from the rare and dense metal tantalum. Widely used in electronics, medical, aerospace, and industrial fields.

Tantalum Tungsten Alloy Wire – On spool

Tantalum wire can remove hydrogen, oxygen and nitrogen from the atmosphere, making it ideal for vacuum applications in the lighting industry. Tantalum is corrosion-resistant and has good thermal conductivity, making it ideal for use in harsh and corrosive environments. It can also be used to make heating elements, vacuum tubes and other high-temperature parts.

Edgetech Industries LLC specializes in providing high-purity, uniformly shaped, highest-density tantalum wire for use in semiconductor, chemical vapor deposition (CVD), PVD and more. In addition to pure tantalum wire, we also offer high-quality tantalum tungsten wire and tantalum wire. Tantalum-niobium alloy wire has competitive prices.

Tantalum Niobium Alloy Wire – In coil

Tantalum wire is used in:

-Electrical: Tantalum wire is used in the electrical industry to make capacitors due to its high dielectric constant and reliability. It is also used in resistors and other electronic components.

-Aerospace: Tantalum wire is suitable for aerospace applications due to its high tensile strength and corrosion resistance. It can be used in aircraft and spacecraft components that require lightweight yet strong materials.

-Automotive: Tantalum wire is used in the automotive industry for components that require high corrosion resistance and strength, such as exhaust systems and fuel lines.

Pure Tantalum Wire – On Spool

-Oil and Gas: In the oil and gas industry, tantalum wire is used in downhole tools and other components that must withstand extreme temperatures and pressures.

-Defense: Tantalum wire is used in defense applications due to its high tensile strength, corrosion resistance and ability to withstand extreme environments. It can be used in ammunition, weapons and other military equipment.

-Medical: Tantalum wire is biocompatible and can be used in medical devices that require high strength and corrosion resistance, such as orthopedic implants and surgical tools.

 

Tantalum wire packaging

Our tantalum is clearly tagged and labeled externally to ensure efficient identification and quality control. Great care is taken to avoid any damage on items which might be caused during storage or transportation. Outer package is usually wooden crate.
