Performance properties not available from a single metal.

VPE utilizes diffusion bonding as well as other methods to manufacture laminated & clad metal sheet.  As a result, the sheet is bonded at the atomic level.  Furthermore, it comes in a wide range of alloys as well as configurations.

Moreover, laminated & clad metal sheet provides a means of creating a composite material with performance properties not available from a single metal.  In addition, sheet properties may be tailored to a particular application, e.g. bending strength, thermal as well as electric conductivity, reduced porosity, as well as corrosion resistance.

The sheet is routinely in a tri-layer configuration.  However, also available are bi-layer as well as multiple repeating layer fabrications.

Materials bonded e.g.:

  • Aluminum
  • Bimetallic (dissimilar metals)
  • Carbon Steel
  • Composites
  • Copper
  • Nickel-based Alloys
  • Precious Metals
  • Refractory Metals
  • Stainless Steel
  • Titanium

The surfaces are generally provided in an as-bonded condition.  However, the surfaces may optionally be finished with various coatings e.g.:

  • Dark chrome oxide (for stainless steels)
  • Nickel plating
  • Copper plating
  • Polished
  • Blasted

VPE’s variety of diffusion bonding furnaces allow for various sizes of sheet e.g.:

  • Sheet sizes to 1.5 meters x 3 meters
  • Sheet thicknesses from less than 0.0004 in. to greater than 5 in.
  • Assembly weights to 60,000 lbs.

If necessary, internal features can be preserved inside the bonded part e.g.:

  • Heating elements
  • Fluidic channels

A wide variety of industries e.g.:

  • Power generation
  • Solar energy
  • Thermal transfer
  • Oil & Gas
  • Chemical processing
  • Cryogenic/refrigeration
  • Semiconductor
  • Space
  • Marine
  • Electrical
  • Structural
  • Transportation
  • Aluminum smelting
  • Desalinization
  • Food processing
  • Paper as well as Pulp
  • Cutlery
  • Jewelry

Many applications e.g.:

  • Weld transitions
  • Corrosion resistance, e.g. chemical processing
  • Corrosion resistance, e.g. galvanic
  • Maintain electrical connections
  • Reduce oxidation as well as connectivity concerns
  • Reduce structural weight
  • Maintain strength at high temperatures
  • Lower the porosity of the metal(s)
  • Solar cell cooling
  • Cold plates, as well as panels, cooling
  • Particulate matter cooling as well as heating
  • Isothermal panels
  • Sputtering targets
  • Heat pipes
  • Heat exchangers
  • Clad knives
  • Makume-gane jewelry
