FAQs

What is Samarium Cobalt (SmCo)?

Samarium Cobalt is a type of rare-earth magnet known for its excellent high-temperature performance and strong resistance to corrosion, making it suitable for demanding environments.

Are these magnets stronger than Neodymium magnets?

No, while Samarium Cobalt magnets are very strong, Neodymium magnets generally offer higher magnetic strength for their size, but at the cost of lower temperature resistance and corrosion resistance.

What is the maximum operating temperature for these magnets?

These Samarium Cobalt magnets can withstand and operate effectively in temperatures up to 300 degrees Celsius (572 degrees Fahrenheit).

How should I store these magnets?

Store them away from electronic devices and magnetic media. It's best to keep them separated by non-magnetic material or stored with keeper bars to prevent self-demagnetization.

Can these magnets be used outdoors?

Yes, their superior resistance to corrosion makes them ideal for outdoor applications where exposure to moisture or elements is a concern.

What are the dimensions of each magnet?

Each disc magnet measures 15mm in diameter and 2mm in thickness, with a tolerance of +/-0.1mm.

How many magnets are in this pack?

This pack contains 10 Samarium Cobalt disc magnets.

Troubleshooting

Magnet loses magnetic strength over time.

Ensure the magnet is not exposed to temperatures exceeding its maximum operating temperature (300°C). Also, check that it is not stored in a way that leads to self-demagnetization; store with keepers or separated.

Magnets are difficult to separate.

Use a sliding motion to separate them rather than pulling directly apart. Use a non-magnetic tool or a piece of wood or plastic to gently lever them apart if necessary.

Magnet chipped or cracked.

Handle magnets with care, avoiding strong impacts or snapping them together. If chipped, the magnetic strength may be reduced, but it can still be functional depending on the application. Inspect for further damage.

Pros and Cons

Pros

  • Withstands very high operating temperatures.
  • Excellent resistance to corrosion and chemical attack.
  • Stable magnetic properties even in extreme heat.
  • Suitable for outdoor and demanding industrial applications.
  • Precise dimensions for consistent performance.

Cons

  • Less powerful than neodymium magnets of similar size.
  • Can be brittle and require careful handling.
  • Higher cost compared to ferrite magnets.
  • Requires specific handling to avoid demagnetization from opposing fields.

Setup, Compatibility & Care

These magnets are ready for use out of the box. Ensure correct pole orientation when integrating them into magnetic circuits.

Compatibility: Generally compatible with most ferrous metals. For electrical applications, ensure compatibility with the specific motor, sensor, or device design.

Care:

  1. Handling: Handle with care to avoid chipping or cracking, especially when separating magnets or when they are attracted to each other.
  2. Storage: Store magnets away from sensitive electronic equipment and magnetic media. It is recommended to store them with keeper bars or in a configuration that keeps them separated to avoid self-demagnetization over time, especially if stored for extended periods.
  3. Cleaning: Clean with a dry or slightly damp cloth. Avoid using harsh chemicals or abrasive materials, which could damage the surface coating or the magnet itself.
