Overlay cladding is a process by which dissimilar layers of
metals are bonded together. This is a metallurgical
process which uses no adhesives or filler materials.
It is accomplished through the use of extreme pressure
and, in some cases, heat. The process can produce
what are commonly called single clad (two layers),
double clad (three layers), and in some specific instances
as many as seven layers. All Clad Metal Specialties
overlays are custom made to your exact specifications.
Our processes have the capability of bonding such
dissimilar metals as nickel to gold, tin to copper,
silver to aluminum. The combinations available, limited
only by the designers imagination, can be manufactured
in widths from .100" to 6", and thicknesses
from .001" to .125".
Typical combinations for the semiconductor industry
include silver double clad on aluminum, lead and tin
alloys clad on all base metals including gold, tin,
gold silicon and gold germanium clad on nickel iron,
kovar, molybdenum and copper
Combinations produced for the switch and electro-mechanical
industries include silver and silver contact materials
clad to all available base materials (copper, kovar,
phosphor bronze and brass). Silver brazing alloys
are available clad to all base metals as discussed
