MetallLaminate

MetallLaminate is a laminated metal composite material formed by bonding thin metal skins to a core layer, or by assembling multiple metal sheets with an interlayer to produce a single, flat sheet. The most common configuration uses two outer metal skins—typically aluminum or stainless steel—bonded to a polymer, resin-impregnated, or foam core. This architecture yields a lightweight, rigid panel with a high-quality surface.

Manufacturing methods include adhesive bonding, diffusion bonding, roll bonding, or hot-press bonding, often under heat and pressure. The choice of core material and surface finish, as well as surface pretreatment of the metals, are critical to bond durability, dimensional stability, and resistance to moisture and chemicals.

Key properties include high bending stiffness and impact resistance for the thickness, good surface smoothness, and tunable thermal and acoustic performance. Corrosion resistance depends on the metal skins and coatings; electromagnetic shielding can be achieved with conductive metal layers. Dissimilar metal layers can introduce thermal expansion mismatches that must be managed in design.

Typical applications span architectural cladding, interior wall panels, and furniture, as well as automotive and aerospace components, consumer electronics housings, and packaging where additional protection or EMI shielding is desired.

Considerations for MetallLaminate include cost relative to solid metals, recyclability challenges due to bonded layers, and potential delamination if exposed to harsh environments or mechanical damage. Proper inspection, edge sealing, and compatible joining methods are important for long-term performance.
