The Power of Composites: Bonding Dissimilar Metals for Better Results

Apr. 22, 2022

Common welding techniques include explosion welding, which joins metal sheets together in a solid state while retaining the mechanical, electrical and corrosion properties of each metal; roll welding, a solid-state welding process that passes two or more metals through a pair of flat rollers to bond the different metals; or overlay welding, which melts a cladding layer onto the surface of a similar metal to form a stronger base material. 


Composite metals usually consist of composite steel, joining steel or stainless steel with reactive metals as well as nickel, copper and aluminum alloys. The composite metal steels are then designed into cylinders, plates, tube sheets and transition joints for heat exchangers, tanks, process vessels, material handling equipment, storage equipment and other products.

Common Composite Materials

Some examples of common composite metal combinations and their many benefits include

● Copper over steel helps improve electrical conductivity, corrosion resistance and ease of soldering for immersion heaters and electrical switch components.

● Nickel on steel provides corrosion and erosion resistance for furnace components, blowers and chemical equipment. It is more durable than plating.

Titanium on carbon steel ensures resistance to high temperature corrosion, which is especially desirable for mining operations.

● Silver on copper provides oxidation resistance to conductor surfaces for high frequency electrical coils, conductors and braiding.

● Gold on copper creates chemical resistance to low-cost base metals for chemical processing equipment.
