The product is a flat copper alloy metallurgy rolling, may comprise aluminum, beryllium, cadmium, lead, chromium, zirconium, and other elements depending on the purpose of the material.
The chemical composition of bronze foil may be tin and Tinless. Bronze tin foil containing more than 4% Sn, is characterized by low shrinkage. Aluminum bronze can include up to 8% Al, is flexible, easy punching. Beryllium bronze contains up to 2% Be, has high elasticity, but somewhat higher in cost. Silicon bronze has a lower cost.
The differences are characterized by rolling method. The foil is available in two types:
? Hot, soft is indicated in the letter M mark;
? cold, hard, designated in the letter of Mark T.
Stamps bronze alloys shall comply with GOST 613, 5017 - for the bronze and tin 493, 18175 - for bronze Tinless.
Usually offered assortment - a thickness of 0.01 to 0.5 mm.
Let out on the basis of various alloys, bronze foil is an anti-friction property, wear resistance, elasticity, thermal conductivity, excellent resistance against corrosion, has good processability and biological inertness, aesthetic.
Due to its properties is widely used in engineering, typography, in electrical engineering. Bronze foil is used in the manufacture of electronic parts, components and parts requiring good thermal conductivity in printed circuit boards. Bronze foil is popular among designers and artists for the production of jewelry and art objects.
