Roll Bonding
Specializing in the direct bonding of aluminum alloys
Roll bonding, also known as roll welding (ROW), is a unique welding process. Two or more metals are guided through a set of rollers that produce extreme pressure. As a result, a metallurgical bond occurs and a new material is formed by the two metals. The high pressure and reduction in thickness produces a uniform bond that is stronger than the weaker material and leaves no room for the galvanic corrosion process to start.
Designs begin by selecting the correct materials for the application. Rather than choosing just one metal with limited advantages and distinct disadvantages, Spur creates a clad with the combined advantages of multiple metals. This provides the ability to mix metals for optimal weight, conductivity, corrosion resistance and cost. Not only can Spur combine metals, but we also have the ability to put material just where it is needed through both inlay and overlay combinations. We specialize in the bonding of aluminum alloys without the need of a low strength interlayer.
Bi-Metal
Spur's roll bonding process provides a very uniform and strong connection between dissimilar metals.
Multi-Metal™
We bond two or more metals together to enable the optimal laminated metal combination for your application.
Partial-Clad™
Spur has the unique ability to bond metal just where it is needed, with both overlay and inlay metal combinations.
Applications
Enhance material properties
In many markets, the ability to create innovative solutions is heavily dependent upon materials properties. Material selection
is driven by the optimization of one material property at the trade-off of other properties. Clad materials can deliver multiple optimized
material properties for unique applications where weight, electrical conductivity, thermal conductivity and corrosion are an issue. Spur currently serves customers in
a wide range of applications and markets.

What is a metallurgical bond?
A permanent connection between metals
A metallurgical bond is a bond of metals characterized by diffusion, alloying, or intermolecular attraction caused by high pressure. This allows dissimilar metals to bond together as one without the risk of harmful galvanic corrosion. With most alloys, Spur’s roll bonding process allows this to occur all while maintaining a bond strength greater than the weaker of the two materials .
Unlike traditional adhesive and fastening methods for joining metals, clad metals have a complete metallurgical bond that results in no increase of electrical or thermal resistance and permanent high strength. In addition, parts can be fabricated utilizing standard machining methods.
- Lowest bond porosity for hermetic and vacuum applications
- Higher temperature resistance than other Bi-Clads
- Provides direct bonding of aluminum alloys without a low strength interlayer
- Greater material thickness flexibility
