Balerion Senior Associate Aidan Daoussis sits down with Vulcan Elements Co-Founder & CEO John Maslin to discuss rare earth magnet manufacturing and supply-chain security.
In this conversation, John explains Vulcan Elements’ approach to domestic manufacturing of permanent rare earth magnets. These magnets are a critical input for electric motors, defense systems, aerospace applications, and advanced industrial equipment. The discussion focuses on why magnets, rather than raw rare earth materials alone, represent the true bottleneck in the supply chain, and how Vulcan is building vertically integrated manufacturing capability inside the United States.
Aidan and John cover the technical requirements of magnet production, current global supply concentration, qualification standards for defense and aerospace customers, and how reshoring magnet manufacturing changes risk profiles for both commercial and national-security applications.
