niobium metal foil

Product Introduction 

Niobium metal foil is a thin niobium product used in applications where corrosion resistance, high-temperature stability, and good ductility are required. It can be supplied in different thicknesses and widths according to the application and processing requirements.

Niobium foil is available in commercially pure grades and can also be supplied according to specific material specifications. For applications requiring high purity or special material properties, the required grade and chemical composition should be confirmed before production.

Located in Baoji, China's renowned "Titanium Capital," we combine decades of metallurgical expertise with state-of-the-art manufacturing capabilities. Our niobium foil products serve customers across 50+ countries, including the United States, Germany, South Korea, and Singapore.

Material Properties of Niobium Foil

Niobium is a refractory metal with a melting point of approximately 2,477°C. It has good chemical stability and corrosion resistance in many environments.

The material also has good ductility, which makes it suitable for producing thin foil and for applications where the foil needs to be formed or processed further.

Niobium becomes superconducting below its transition temperature of approximately 9.25 K. This property is relevant to superconducting and cryogenic applications.

Important properties of niobium include:

High melting point

Good corrosion resistance

Good ductility and formability

Good chemical stability

Low-temperature superconductivity

Suitable for thin and lightweight components

The actual properties of niobium foil depend on purity, thickness, material condition, and manufacturing process.
