Foil, of copper, of a thickness not exceeding 0.15 mm

CPC v2.1 Code: 41515

About foil, of copper, of a thickness not exceeding 0.15 mm

cpc code 41515 covers the production of thin copper foil, a critical material used in a wide range of industries. Copper foil is an essential component in the manufacture of printed circuit boards, which are the backbone of modern electronics. This industry plays a vital role in supporting the growth and development of the broader electronics and technology sectors, which are key drivers of economic progress worldwide.

Production process

The production of copper foil involves a complex process of rolling and annealing. Copper ingots or sheets are first heated and then passed through a series of rolling mills, which gradually reduce the thickness of the material to the desired specification. The rolled foil is then subjected to an annealing process, where it is heated and cooled to improve its ductility and workability. This process is repeated multiple times to achieve the final thickness of 0.15 mm or less.

Production inputs

The main inputs required for the production of copper foil under cpc code 41515 include high-purity copper as the primary raw material, as well as specialized rolling and annealing equipment. The copper used must meet strict purity standards to ensure the quality and performance of the final product. Additionally, the production process requires a significant amount of energy, primarily in the form of electricity and natural gas, to power the rolling mills and annealing furnaces.

Production outputs

The primary output of this industry is thin copper foil, which is then used in the manufacture of 32100 Electronic components and boards, such as printed circuit boards. Copper foil is also used in the production of 25930 Metal containers, 25999 Other fabricated metal products n.e.c. and various other metal products. The copper foil industry plays a crucial role in supporting the growth and development of these downstream industries, which are essential components of the broader manufacturing and technology sectors.
