What are friction metals, and how are they used in manufacturing?

Friction metals refer to materials that are engineered to perform under high-friction conditions, often used in applications such as brake pads, clutches, and industrial machinery. These metals or metal composites are designed to maintain strength, resist wear, and manage heat buildup during continuous contact and movement.

In welding and joining technologies like Friction Stir Welding (FSW), friction plays a central role—though the term “friction metals” is less commonly used in this context. Instead, the focus is on how metals respond to heat and pressure generated by friction. Materials like aluminum, copper, and magnesium alloys are often used in FSW because they respond well to the frictional heat and plastic deformation required to form solid-state welds.
