Niobium foil Description

Niobium is a shiny grey metal that takes on a bluish tinge when exposed to air at room temperature. Roughly ninety percent of Niobium is used in the production of high-grade structural steel, a great deal in the form of the niobium sheet, followed by its use in superalloys for such applications as jet engine components, gas turbines, rocket subassemblies, turbocharger systems, and heat-resisting and combustion equipment.

Stanford Advanced Materials (SAM) is a worldwide supplier of high-quality Niobium Foil & Sheet who has over two decades of experience in the manufacture and sale of Niobium products. Our high-quality Niobium Foil is widely used in chemical anti-corrosion, capacitors, optical target materials, superconductors, medical treatment, refrigeration, etc.

Niobium Foil Applications

Niobium Foil is very stable so that it can replace stainless steel in the inorganic acid produce, machine life can improve dozens of times with it. Other applications include its use in chemical, welding, nuclear industries, electronics, optics, numismatics, and jewelry. Niobium's low toxicity and ability to be colored by anodization are particular advantages. Our high-quality niobium foil widely is used in anti-corrosion, capacitors, optical target material, superconductors, medical treatment, refrigeration, etc.

Niobium Foil Packaging

Our Niobium foil is carefully handled to prevent damage during storage and transportation and to preserve the quality of our product in its original condition.
