Definitions

  • the invention relates to a process for the production of tinned strips or sheets made of copper or a copper alloy. Furthermore, the invention relates to the use of tinned strip-shaped semi-finished products in the construction sector, in particular for roofing or facade cladding.
  • the invention has for its object to provide a method with which the visual appearance of the surfaces of ribbon-shaped semi-finished products made of copper or a copper alloy can be improved. Furthermore, the relatively high sensitivity of the surfaces to mechanical and chemical impairments should be reduced.
  • strip-shaped semi-finished copper product is first rolled by means of a textured work roll to set an average roughness depth in the range from 3 to 12 ⁇ m and then continuously coated with tin or a tin-based alloy, and the ratio of the average roughness depth to the thickness of the Tin layer is greater than 1.2, preferably greater than 2.
  • the surface of a cold-rolled and possibly degreased strip made of SF-Cu with a thickness of 0.72 mm and a width of 670 mm was roughened on one side in a duo stand with a textured work roll.
  • the essentially regularly textured surface of the copper strip had an average roughness depth of about 5 ⁇ m after the rolling treatment.
  • the copper tape was then coated with a galvanically applied pure tin layer of 1.2 ⁇ m thick.
  • the texture of the relatively thin layer of pure tin applied to the textured strip surface is very evenly matt-glossy, insensitive to handling and also proves to be sufficiently opaque.
  • the non-textured back of the tape, which is also coated, on the other hand has a high light reflectivity. During handling, there are conspicuous fingerprints and the resulting uneven discolouration of the surface. However, these disadvantages do not disturb on the back of the tape.
  • a metallographic examination of the microstructure of the tin layer showed an even distribution of the tin particles on the textured carrier material.
  • the measurement results are summarized in the following table.
  • the average roughness (average roughness R a ) was measured both in the rolling direction (L) and transverse to the rolling direction (Q).
  • Sample Test direction Surface roughness ( ⁇ m)
