Aluminum Friction Welding

Make Your Parts Durable, Corrosion-Resistant, and Lightweight

Aluminum Dissimilar Metal Welding

Aluminum is a lightweight metal with great corrosion resistance and high thermal and electrical conductivity. However, aluminum is considered one of the more challenging common metals to weld because of its high heat movement and soft texture.

Through dissimilar metal welding, you can expand the possibilities for bimetallic component design and develop parts tailored to your performance, production, and application goals.

Can Your Application Be Friction Welded?

Tap into Your Part’s Potential with Aluminum Friction Welding

Aluminum can be difficult to weld with conventional welding techniques. Due to its high heat movement, it is difficult to control the weld joint when using melting-based welding processes. Furthermore, its soft texture makes it more sensitive to distortion and deformation.

However, through aluminum friction welding, aluminum is joined with dissimilar metals in a solid but plasticized state. Rather than melting them, it uses frictional heat and forging pressure to form a strong, high-quality weld.

Can You Weld Aluminum to Copper?

Yes, you can weld copper to aluminum, welding copper to aluminum creates components that are lightweight, conductive, and built for reliable performance.

Friction welding copper to aluminum electrical components, for example, does not require filler metals. With properly developed welding parameters, an aluminum-to-copper friction weld can form a high-integrity bond that supports reliable joint performance.

Common Applications:

  • Lithium battery construction
  • Electric vehicle applications
  • Aluminum components for electrical assemblies
  • Other high-conductivity electrical applications

Why Use Friction Welding for Aluminum Applications

Friction welding aluminum allows you to create bimetallic components with consistent weld joint quality, strong mechanical properties, and repeatable production results that benefit your parts project.

  • Cost-Efficient Joining: Friction welding can reduce production steps by requiring minimal joint preparation and no filler material. Unlike many traditional welding techniques, this solid-state welding process uses frictional heat and controlled pressure to create strong welded joints without added materials.
  • Lightweight Component Design: Copper-to-aluminum welding promotes weight reduction, improved conductivity, and component efficiency. This allows manufacturers to use aluminum where lightweight performance matters while placing copper where electrical or thermal conductivity is required.
  • Greater Design Flexibility: Friction welding gives manufacturers greater freedom to design aluminum, copper, and other dissimilar material components around performance, geometry, manufacturability, and application-specific requirements.
  • More Durable Components: As a controlled solid-state joining process, friction welding creates high-integrity bonds without melting the base materials. This helps preserve mechanical properties and support long-term performance in demanding environments.

Friction Welding Technologies

Friction welding processes differ from the various methods of relative motion used.

 Rotary Friction Welding

Rotary Friction Welding (RFW) is a solid-state welding process where one component rotates at high speed while being pressed against a stationary part. This can be a strong option for aluminum friction welding when the part geometry is round, cylindrical, or otherwise suited to rotation.

low force friction welding

Low Force Friction Welding

Low Force Friction Welding is MTI’s newest solid-state process. It uses an external heat source to weld components, reducing the forces required compared with traditional friction welding. It has less flash formation and shorter weld cycles, saving time and costs in the welding process.

Try It Today:

Our Weld Development 2.0 services allow you to test and compare traditional welds for your parts with Low Force Friction Welding.

Linear Friction Welding

Linear Friction Welding, or LFW, is a solid-state process that uses linear motion to join a moving component to a stationary one. This makes it useful for aluminum parts that are non-symmetrical, complex, or difficult to join with conventional friction processes.

Try It Today:

Test and produce full-scale parts with one of the largest Linear Friction Welding machines in the world with MTI’s Contract manufacturing services.

Friction stir welding

Friction Stir Welding

Friction Stir Welding (FSW) uses a rotating pin tool to move through the joint line and stir the materials together to create a watertight weld. Friction Stir Welding aluminum in the electric vehicle industry creates lightweight parts that seal out moisture and dust.
