Overview & Properties

It is possible to combine multiple types of the composite materials* we manufacture.

We call these products "composite metal materials."


*Composite metal materials are materials like those below that are composed of a single metal with additional functions.

 • Clad metals — Materials composed of two or more different types of metals

 • OVIONE™ Coat — Materials with functional resin coatings

 • Molten-solder plated metals — Metal materials coated with molten solder

 • Multigage metals — Materials with surfaces that are processed to create uneven profiles

 • Plating — Materials treated with plating such as Au, Ag, Ni, Sn, and Sn reflow.

(Plating work is outsourced, but Tokkin guarantees quality from materials to the post-plating process.)



A wide range of combinations are available including:

  1. OVIONE™ Coat + plating
  2. Clad metals + molten solder
  3. Clad metals + multigage metals
  4. Clad metals + OVIONE™ Coat + multigage metals


These kinds of composite metal materials are often used in resistor materials (clad metal + molten solder plating + OVIONE™ Coat + multigage metals) and connector materials (OVIONE™ Coat + tin plating).


Recently we have been receiving more and more requests from electronic components manufacturers and other firms for materials like these that combine technological elements. Many companies are seeking to differentiate themselves technologically from their competitors.

Tokkin Advantages

 Reduce number of downstream processes

 At the time we ship materials, they have already had functions added in downstream processes, which allows you to reduce the number of process after parts have been processed.


 Reduce total costs

 We add downstream processes to the material stage, which so that you no longer have to outsource them. This allows you to reduce outsourcing costs and the hassle of managing subcontractors, and ultimately helps to reduce total costs.


 Manufacture parts with little variation in quality (Improve quality)

 Since strips are processed (given additional functions) at the material production stage, it is possible to make uniform parts with little variation.


 Differentiate your company from the competition

 Adding shapes and functions that have not been possible to achieve in downstream processes up until now enables you to differentiate your company from your competitors.
