Friction Welding Applications for Bimetallic & General Use

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 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.
