The foil

The foil

Supplier — the company AvecGlob — offers at affordable prices from the manufacturer foil of niobium in a wide range of thickness and width. The supplier guarantees the timely delivery of products to any address specified by the consumer /

Technical specifications

Niobium is a silver-white metal, characterized by very high corrosion resistance due to the presence on it of a superficial strong oxide film.

The metal has superconducting properties, which is used in the technological processes of plastic deformation in the production of products of particularly complex configuration without cracking. The metal has paramagnetic properties. Production of foil from niobium is regulated by the technical requirements of GOST 16099−80 and GOST 16100−80.

Urgency of application

Niobium is used in alloys, including stainless steel. This improves the strength of the alloys, especially at low temperatures. Products from niobium foil are used in the manufacture of electronic control systems for jet engines and rockets, and for the production of building envelopes, long-term operation of which is possible at low temperatures. Body products from niobium foil are used in superconducting magnets for particle accelerators, MRI scanners and NMR equipment.

Chemical composition

GOST 16099−80 and GOST 16100−80 provide for the production of Nb-1 niobium foil. The percentage of admissible impurities is indicated in the table (niobium — the rest):

Nitrogen Oxygen Hydrogen Silicon Tantalum Iron Titanium Tungsten + molybdenum Carbon
0.01 0.01 0,001 0.005 0.1 0.005 0.005 0.01 0.01

Assortment and application features

Niobium foil is made from 0.03 to 2.5 mm thick, with a width of 20 mm and a length of 50 mm. At the request of the consumer, a niobium foil can be produced in another size range.

Supplier — the company AvekGlob — offers to purchase niobium foil in a variety of thickness and sizes. Products can be bought at a price formed on the basis of European and world standards of production. Implementation is possible in bulk and retail, for regular customers, a flexible system of discounts operates.
