Tantalum Ingot Supplier
Talk To Us – We’re Here To Help
Tantalum Ingots (Ta Ingots) of top quality are available at Solitaire Steel. Made from Tantalum (Ta), this dark blue-gray metal is known for being heavy, ductile, and hard, with exceptional corrosion resistance. It stands up well to chemicals, especially at temperatures below 150°C, and can only be dissolved by hydrofluoric acid. Tantalum has a high melting point and forms extremely thin, protective oxide layers, making it ideal for a wide range of applications.
As a leading global supplier, Solitaire Steel offers Tantalum Ingots at competitive prices. We also provide custom tantalum products tailored to your specific requirements.

FAQs
Tantalum ingot is a solid piece made from tantalum (Ta), a dark blue-gray metal known for its heaviness, ductility, and hardness. It exhibits excellent corrosion resistance, particularly against chemicals at temperatures below 150 °C, and can only be dissolved in hydrofluoric acid.
Tantalum ore is primarily used in the production of electronic components. The oxide layer that forms on tantalum acts as an insulating dielectric, enabling high capacitance in small volumes, especially for capacitors and resistors in electronics.
