Friction welding makes it possible to join metal combinations not normally considered compatible, such as aluminum to steel, copper to aluminum, titanium to copper, and nickel alloys to steel. Since dissimilar materials can be joined, a significant cost savings is possible by designing bimetallic parts that use expensive materials only where needed. MTI Friction Welding Ltd has experience with many bimetallic applications. Some include: copper to aluminum electrical connectors, aluminum to stainless steel copier fuser rollers, titanium to copper electrodes used in seawater desalinization cells, and stainless to alloy steel propeller shafts for outboard motors.

As a rule, probably all metallic engineering materials which are forgeable, are weldable by the friction welding process.

Weld integrity is a must within the oil mining industry. Proven reliability of friction welded connections, coupled with the process advantages such as being clean, fast, consistent, and free of operator-induced error, makes friction welding one of the leading methods of joining flanges to valve bodies, drill pipe, high-pressure hose couplings, and manifold tubes.
