Toyo Kohan is the world's leader in developing and utilizing "FINE CLAD" high function bimetallic lamination materials using a "surface activation sealant method", a new ambient temperature sealing technology.
"FINE CLAD" is manufactured at ambient temperatures in a vacuum and low draft pressure welding, which differs from conventional cladding materials with little effect on materials caused by heat and process stress.

Coils made of cladding materials
Copper/Nickel, Nickel/Aluminum, Aluminum/Stainless Steel Clad

Features Manufacturing Method and Specifications Mechanical Characteristics Application Examples Prizes

Features

Material sealing (pasting) available at low pressure (low load).

No material characteristics (hardness, structure, etc.) changes before or after sealing.
Superb thickness precision.
Sealant phase flatness.

Foil layer (10 µm or greater) available.

Materials with plating and difficult thicknesses can be cladded.

Various material combinations available (Cu/Ni/Cu, Al/Al, Cu/Al, Al/SUS, etc.)

Sealed in vacuum at ambient temperatures.

No alloy layer is created to sealant phase.

Toyo Kohan FINE CLAD is an all new composite (bimetal).

■ Comparison of FINE CLAD to conventional cladding
Item	Toyo Kohan FINE CLAD	Conventional Cladding
Phase Flatness	Good	Poor or bad
Phase Alloy Formation	None	Yes
Foil Sealing	Good	Bad
Thickness Reduction Rate	0.1 to 5.0%	30 to 70%

This may vary according to material combinations.
