What are the main applications of FSW in defense industry?

Friction stir welding provides an answer for optimal thermal management in the field of Defense. Liquid cold plates are used to cool embedded systems such as commercial radars or control and power electronics. Allowing the assembly of any type of aluminum alloy, FSW facilitates the fabrication of machined aluminium cold plates. FSW is also used in the manufacture of lamellar heat exchangers and heat spreaders in the defense industry.
Friction stir welding has made it possible to use aluminium grades that are shielded or have very high mechanical properties.
