Definition of clad material

Clad metal refers to a material wherein the parent layer is composed of metal / nonferrous metal where other metal / nonferrous metal layers are bonded to one or two of its sides. New characteristics that differ from its parent material are added to it.

  • Clad metal can be produced through processes such as welding, rolling, casting, and pressing. The layer bonding becomes stronger with time as its base components penetrate into each other.
  • It is a new material created through atomic diffusion bonding of dissimilar metals using the rolling method. Unlike other bonded steel plates, it does not experience delamination even in deform (curve) machining or when left as is for a prolonged period.
Difference between clad and other products

not a material made through simple plating or bonding with chemical adhesives!

Clad is a material made by bonding together metals (including nonferrous metal) through a heat-rolling process. During the process, the metal layers self-destruct and penetrate into each another which, in turn, stabilizes the material itself.

Thus, compared to the existing single-component materials, clad has distinctive characteristics as outlined below.

  • Delamination Impossible
  • Bonding Becomes stronger with time as the interfaces of the metal layers penetrate into each other
  • Complementary aspect The advantages of the single-component metal are maintained, while its disadvantages are complemented by the bonded metal. Also, the advantages of the bonded metal remain as well in a complementary manner, creating a functional material with better performance.
