Clad Metals
│A composite of two or more dissimilar metals

Overview

Clad Metals are the materials consisting of two or more different metals bonded together.
It is a highly functional metal material with composite properties that cannot be obtained with a single material. In Clad Metals, the boundary surfaces between dissimilar metals are diffusion bonded (alloyed by elemental diffusion), so there is less concern about delamination as in plating. Clad Metals can help reduce total costs by reducing processes and lead time and improving quality.
clad shapes

Double-sided inlay (edge inlay) cladding and double-sided edge inlay cladding is also available upon request.

Advantages of TOKKIN

We manufacture custom clad materials in overlay, inlay, edgelay, and stripe designs according to your desirable width, thickness, distance away from the edge, and numbers of strip.


  • Good Bonding Surface Condition
    The bonding surface is in good condition due to metallic bonding. Multi-component alloys can be bonded.
  • Utilization of the Characteristics of Different Metals
    Electrical conductivity, strength, weldability and thermal expansion, etc can be utilized.
  • Multi-layer Cladding
    Multi-layer lamination is possible, not limited to two layers.
  • High Flexibility in Adjusting Thickness Ratio
    Thickness ratio can be adjusted on request for all materials. For example, the cladding layer can be made thicker (several hundred microns, etc.), allowing large currents to flow.
  • Adjustable Hardness
    Hardness can be adjusted by rolling and heat treatment.
  • Various Inlay Claddings
    Striped inlay cladding and Inlay cladding metal with wide width (over 50 mm) is also available.
  • Various Combinations
    There are limitations on base metals and coated metals for plating , but cladding allows a diverse range of materials.
  • Quantity
    Prototype available from 50kg upon request.
    (Lead time and availablity may vary. Please get a quote first.)

Clad metals offer the opportunity to combine desirable properties and/or characteristics of individual metals and alloys into a composite materials “system” that brings infinite possibility!

CS Clad Material

This is a new cladding method that forms a Layer on a base material using the "Cold spray (CS: low-temperature thermal spraying)" technology, in which metal powder is accelerated to supersonic speeds and sprayed in a solid state.
It can be applied to resin and ceramics.
