Extended Product Information

FAQs

What does 'Alnico' mean?

Alnico is an alloy composed primarily of aluminum, nickel, and cobalt, known for its high magnetic strength and excellent resistance to demagnetization and high temperatures.

What is the operating temperature limit?

This magnet can operate up to 500 degrees Celsius (932 degrees Fahrenheit).

What is the pull force?

The pull force is rated at 9kg (approximately 19.8 lbs).

How do I clean the magnet?

Use a soft, damp cloth. Avoid harsh chemicals or abrasive materials that could damage the epoxy coating.

Can this magnet be used underwater?

Yes, its corrosion-resistant properties make it suitable for underwater or sub-sea applications.

What are the dimensions of the magnet?

The magnet measures 40mm x 25mm x 25mm, with individual pole faces of 20mm x 10mm and a 4.5mm hole.

Are the poles clearly defined?

Yes, the North and South poles are on opposite ends, making it ideal for classroom demonstrations.

Troubleshooting

Magnet appears weak

Ensure the magnet is not placed near other strong magnetic fields. Check that the surface it is attracting to is made of a suitable ferrous material and is clean. Verify that the object's weight does not exceed the 9kg pull force.

Epoxy coating is damaged

Minor scratches may not affect performance. For significant damage, consider the magnet's suitability for the intended environment, especially if corrosion resistance is critical. Handle with extra care to prevent further damage.

Magnet is attracting unwanted items

Store the magnet separately when not in use, ideally in a container that shields its magnetic field or with a keeper bar. Keep it away from sensitive electronic equipment and magnetic media.

Pros and Cons

Pros

  • Excellent strength for its size.
  • Durable due to corrosion resistance and epoxy coating.
  • Suitable for high-temperature environments (up to 500°C).
  • Versatile for both industrial and educational use.
  • Clear pole separation for demonstrations.

Cons

  • Pull force of 9kg may be insufficient for very heavy applications.
  • Alnico magnets can be brittle and may chip if dropped.
  • Requires careful handling due to strong magnetic field.
  • Epoxy coating, while protective, can be scratched.

Setup, Compatibility & Care

Setup:

This magnet does not require any specific setup beyond its intended application. The 4.5mm hole can be used with appropriate screws or fasteners for mounting. Ensure the surface the magnet attaches to is clean and free of debris for optimal performance.

Compatibility:

  • Compatible with ferrous metals (iron, nickel, cobalt).
  • The magnetic field can affect electronic devices; keep a safe distance from sensitive equipment, credit cards, and magnetic storage media.
  • Compatible with high-temperature environments up to 500°C.

Care:

  • Clean with a soft, damp cloth. Avoid abrasive cleaners or solvents, as they may damage the epoxy coating.
  • Store magnets away from each other to prevent demagnetization and avoid potential damage from strong attraction.
  • Handle with care to avoid dropping, as Alnico magnets can be brittle.
  • Keep away from heat sources exceeding its operating temperature limit to maintain magnetic properties.
