Frequently Asked Questions

Disc magnets are commonly used in motors, rotary couplings, sensors, electronics, and prototyping applications due to their compact shape and strong magnetic field.

Neodymium disc magnets offer higher magnetic strength, while samarium cobalt disc magnets are preferred for high-temperature or chemically harsh environments.

Engineers often start with small-to-medium diameters (3–12 mm) for sensor alignment, robotics, and medical device testing. Testing multiple diameters helps confirm the right “fit” and pull force before moving to production.

Yes, disc magnets can be used in compact motor designs, especially when space is limited. For rotational systems, consider both neodymium for strength and Samarium Cobalt for high-temperature stability.

We provide a wide range of coatings to match different applications. Common options include nickel, parylene and rubber. Nickel is the standard for durability, parylene are biocompatible and preferred for medical uses and rubber coatings improve grip and impact protection. Additional specialty coatings are also available depending on your requirements.

Yes. Through our engineering division, SM Magnetics, we can design and manufacture custom sizes, magnetization directions, and specialized coatings. You can either submit a custom request form or contact us directly to speak with our experts.
