Explosion-Bonded Clad Plates
Clad plates combine a corrosion-resistant or specialty-metal layer with a structural base material. Explosion cladding is a solid-state pressure-bonding process used to create a metallurgical bond between selected metals.
Cladding combinations, dimensions and composite thicknesses can be considered against project requirements and technical feasibility. Cladding on one or both sides of a base plate, including multilayer composites, may also be possible.
Clad Plate Options
Material combinations are reviewed according to the intended service, fabrication requirements and project specification.
How Explosion Cladding Works
In explosion cladding, the cladding plate is positioned above the base plate with a controlled stand-off gap. A specially designed explosive layer accelerates the cladding plate toward the base plate. The plates collide progressively at high velocity, creating a metallurgical bond across the interface.
The collision conditions are controlled to promote bonding and help remove surface contaminants such as oxides and gases from the interface. Process variables—including explosive loading, propagation characteristics, stand-off distance and collision angle—are selected to suit the materials and product design.
Process Characteristics
Clad Layer & Base Materials
A range of cladding and backing materials can be considered. Specific grades and combinations should be confirmed against service conditions, design requirements and technical review.
Available Material Families
| Component | Material Options |
|---|---|
| Clad Layer | Stainless steel, duplex, titanium, zirconium, tantalum, aluminium bronze, nickel, nickel alloys, aluminium, copper and copper alloys |
| Base Material | Carbon steel, stainless steel, alloy steel, copper and aluminium |
Other material combinations may be considered on request, subject to technical feasibility and availability.
Clad Plate Configurations
Cladding can be applied to one or both sides of a base material. The same or different cladding metals may be specified on each side. Multilayer clad composites may also be considered for suitable applications.
Certain clad products may be suitable for further rolling or extrusion into thinner gauges. This is assessed on a case-by-case basis, considering technical feasibility and required quantities.
Configuration Options
Advantages of Clad Products
Clad products combine selected properties of different metals in a single composite. The suitability and performance of each product depend on the material combination, design and service conditions.
Key Advantages
Request a Clad Plate Review
For a project enquiry, provide the required clad and base materials, plate dimensions, cladding thickness, configuration, applicable specification and intended service. Technical feasibility, processing options and delivery details can then be reviewed.
