Foil of noble metals and alloys – thin-rolled semi-finished product of rectangular cross-section of precious metals and alloys based on them.
Foil is produced by rolling and flattening precious metals with a minimum sheet thickness (from 0.005 mm to 0.90 mm).
Methods of obtaining: rolling, spraying, electrolytic method.
The chemical composition of the feedstock and the purity of the alloy is governed by quality standards.
Type of feedstock: platinum, gold, silver (platinum group metals).
The foil differs in small thickness (in several microns), excellent operational characteristics. Well stamped, amenable to pressing, forging. Excellent cut, cooked.
The high density of the material contributes to the unique performance characteristics. The foil made of precious metals does not rust or oxidize; it conducts heat and electric current well.
It differs by type of feedstock, rolling thickness, sheet parameters.
Foil is used in the chemical and jewelry industry, the production of radio components, circuit boards, contacts. It is used in medicine and dentistry, in scientific research and research.
