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.
Bi-Layer
Tri-Layer
Repeating Layer
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
