Compression Bonded Magnets

Made in the U.S. with a 100% China-Free Supply Chain

As of April 4, 2025, China—supplier of over 90% of the world’s rare earth magnets—has halted magnet exports to the United States. If your business relies on bonded neodymium magnets from China, you're now facing major supply chain disruption

Magnet Applications offers a dependable, domestic solution:

Compression Bonded Neodymium Magnets manufactured entirely outside of China, with full control from powder sourcing to final magnetization and coating—right here in the U.S.

Why Magnet Applications?

The only U.S. supplier offering full-scale compression bonded Neo magnet production with zero reliance on China
100% China-free supply chain
Full in-house control: tooling, coating, magnetization
Trusted by industrial leaders
Fully compliant: ITAR, DFARS, RoHS, REACH

What Are Compression Bonded Neo Magnets?

Compression bonded magnets are produced by combining neodymium-iron-boron (NdFeB) powder with a resin binder and molybdenum lubricant. The mix is pressed into molds and oven-cured, resulting in strong, dimensionally stable magnets with excellent shape flexibility and low tooling costs.

Key Characteristics:

Made from isotropic NdFeB powder via jet casting
Mixed with resin and moly lubricant
Mold-pressed and cured under controlled conditions
Operating temperature up to 150°C (302°F)

How They Compare to Other Magnet Types

Magnet Type	Process	Strength	Shape Flexibility	Best Use Cases
Compression Bonded	Resin-bonded NdFeB powder	Medium	Moderate	Motors, sensors, encoders
Sintered Neodymium	Powder metallurgy	Very High	Low	EVs, high-performance motors
Injection Molded	Nylon-bonded powder	Low	Very High	Sensors, fluid-contact applications

Where These Magnets Perform Best

Compression bonded Neo magnets are not a one-size-fits-all solution. However, in the right application, they offer unbeatable value in cost, lead time, and design flexibility.

Ideal Applications:

Fractional horsepower motors (fans, pumps)
Rotary encoders (speed/position sensors)
Automotive subassemblies (wipers, windows, sensors)
Industrial motors (especially legacy designs)
Aerospace & defense systems (ITAR/DFARS compliant)

Key Benefits:

U.S.-based manufacturing with complete process control
No reliance on Chinese sourcing
Tooling costs as low as $4,000
Lead times as short as 4–6 weeks
Custom magnetization patterns available
RoHS, REACH, DFARS, and ITAR compliant

Important Considerations:

Max temperature: 150°C (302°F) due to resin binder
Must be coated for humid or corrosive environments
Lower strength than sintered magnets—not a 1:1 replacement

Typical Lead Times

Scenario	Lead Times
Existing tooling, no coating	~4 weeks
Magnetization + coating required	~6–8 weeks
New tooling required	~10–12 weeks
Tooling + fixture + coating	Up to 16 weeks
