eVAC Magnetics – Restoring American Dominance in Rare-Earth Magnet Technologies
National security. Economic prosperity. American innovation.
eVAC Magnetics LLC is leading the effort to re-shore critical mineral and rare-earth magnet supply chains to America.
Through our new eVAC facility in Sumter, S.C., we are leveraging 100 years of global industry knowledge, advanced technology, and key U.S. partnerships to protect America’s energy independence, strengthen America’s national security, and create good-paying jobs and career opportunities here at home.
Opened in fall 2025 and scaling to full capacity in 2026, the Sumter facility is a state-of-the-art rare earth neodymium-iron-boron (NdFeB) permanent magnet production facility. NdFeB permanent magnet solutions are essential to mission-critical industrial applications.
eVAC is a proud American company. From sourcing to production and distribution of NdFeB permanent magnet solutions, eVAC’s commitment to America is onshoring manufacturing jobs, protecting American economic and security interests, and further cementing America’s unique energy advantage.
Rare-Earth Permanent Magnets: Mission-Critical Infrastructure
Neodymium-Iron-Boron magnets made of VACODYM® have the highest energy density available today. VACODYM alloys are anisotropic material grades.
Benefits:
- Up to 10 times higher energy densities in comparison to ferrites
- Existing magnet systems can be improved
- New design principles are realized and new fields of application are opened
- New alloy classes can be used for working temperatures above 200 °C
VACODYM magnets are made using a process similar to shaping and hardening fine metal powders. Their strong performance comes from a special base material that naturally creates powerful magnetic force. A thin layer of neodymium around each grain helps the magnet hold that strength more effectively.
Depending on the shape, size, and performance requirements, these magnets are either made from large, pressed blocks or shaped directly with precision presses.
VACODYM magnets fall into three production types (HR, TP, and AP) which simply describe how the material is pressed and aligned during manufacturing.
- HR magnets are made using high-pressure, all-around pressing.
- TP and AP magnets are pressed in one direction, with particles lined up using magnetic fields.
Magnets made with all-around pressure or sideways alignment typically end up 5 to 8% stronger than magnets aligned straight along the pressing direction.
A special finishing technique called grain-boundary diffusion can boost the magnet’s ability to resist demagnetization, raising its durability and stability to very high levels
The rare-earth magnets produced at the eVAC facility can be utilized for a range of mission-critical applications. eVAC has the capacity to meet the ever-evolving needs of both government and civilian clients, which can include:
- Electric propulsion capabilities
- Motors and actuators for AI-enabled robotics
- Guidance systems
- Undulators
- Electric and internal combustion vehicle motors
- Consumer electronics and medical equipment
