Bronze strips

Laminated bronze strip in coil for industrial applications. Wide variety of sizes adapted to the needs of our customers.

Data sheet: Bronze strips

Copper strips are used in a wide variety of industrial applications and are characterised by high electrical and thermal conductivity – ideal for use in electrical components such as connectors, terminals, and conductors in electrical and electronic devices.

Copper is a highly malleable and ductile material, which allows copper strip to be bent and formed into complex shapes without breaking, and has very good corrosion resistance in most environments, including marine and polluted air. This extends the life of copper strip products, especially in outdoor applications or in harsh conditions.
