Friction Extrusion (FE) Technology

Purpose-Built To Push The Envelope

Friction extrusion (FE) technology, invented in 1991 by researchers at The Welding Institute, has long been a subject of interest in materials research. However, its commercial applications were limited due to the lack of suitable equipment.

Until now.

Bond Technologies designed and built the first-ever purpose-built Friction Extrusion machine, and our FE systems are the only FE machines on the market. We have taken FE technology and put it to work for our customers.

Bond Technologies is the only supplier of FE Products.

How is Friction Extrusion superior to Conventional Extrusion?

Conventional extrusion of metals has been around for a long time. Typically, a metal billet is heated and pressed through a die with some shape, producing stock for a multitude of applications.

Extruded materials are often stretched to straighten the material and to increase the yield strength, and then aged to improve ultimate strength.

FE modifies this process by adding severe plastic deformation of the billet as it is extruded through an opening.

This additional step produces the unique advantages of FE over conventional extrusion:

  • The plastic deformation refines the grain structure of the extruded material.
  • Friction and plastic deformation generate all the heat needed for the process.
  • The extreme pressure and deformation consolidate the feed stock, making it possible to make fully dense stock from mixed powders and chips.
  • The refined microstructure has high ductility, which is not possible with other severe plastic deformation methods.

Unique Characteristics of Materials Produced by FE

Materials produced by friction extrusion exhibit unique characteristics, including very-to-ultra-fine grain size, low matrix dislocation density, and the ability to consolidate materials with high porosity. These characteristics make them suitable for a wide range of applications.

Applications of Materials Produced by FE

The applications for materials produced by FE are vast and continue to expand. These materials are used in creep-resistant structures, lightweight magnesium and aluminum components, products with enhanced thermal and electrical properties, and more.

Bond’s FE technology is driving innovation in materials processing. With Friction Extrusion, the possibilities for creating new materials with unique properties are endless, making it a valuable tool for industries such as Automotive, Aerospace, Electronics, and Energy.

How Friction Extrusion Works

Friction Extrusion is a solid-state metal joining process that does not require an external heat source. FE is similar to friction stir welding (FSW) in the way that heat and deformation are produced. FE relies on friction and plastic work produced by relative motion between a non-consumable die and a workpiece. As a result, it is undesirable to liquefy the workpiece, since the source of heating depends on resistance to relative motion. The solid-state nature of the process produces all of its desirable characteristics.

In the friction extrusion process, a rotating die with a grooved feature cut into its face is forced against a billet, which may consist of solid material, swarf, or powder. Relative motion produces friction and plastic work, heating and softening the feed stock. The features on the rotating die deform the material radially inward toward an opening through which the material is extruded. This principle may be produced by a number of tooling arrangements.

Key Advantages of Friction Extrusion Welding ​

High-speed consolidation – no vacuum evacuation required.

Energy efficiency – no auxiliary heating required

Larger extrudate materials – large enough for practical use.

Advanced FE Machines from Bond Technologies

Bond’s FE machines mark a significant advancement in friction-based metals processing. Our FE welding machines boast the extreme force and torque required to extrude feedstock into wire, rod, or tubes of a practical size, opening up new possibilities for metal shaping. Bond’s  groundbreaking machines are designed for the reprocessing of powders, chips, or bulk materials into innovative new materials with unique characteristics.

The FE Series has a wide range of commercial applications. FE has the potential to revolutionize the additive manufacturing industry by producing bar stock from engineered powder, which can then be used as weld wire or stock for a friction deposition system, creating ultra-fine-grained structures.
