Countersunk Neodymium Magnets
Using the strongest and highly cost-effective permanent magnet in the world, neodymium countersunk magnets are ideal and highly recommend on many applications around the house and industry including door closures, holding tools, hanging art on a wall, and more! N35, N42, N48, N52 are popular grades for neodymium magnets.
Samarium Cobalt Countersunk Magnets
Compared with neodymium material, smco countersunk magnet can continuous work at high temperature conditions (up to 350℃). What’s more, smco countersunk magnet has very good corrosion resistance and long-term thermal stability. No surface coating is necessary. They are more often used in industries with special requirements.
Magnetization Direction of Countersunk Rare Earth Magnets
The magnetization direction is very important thing for permanent magnet. It determines the working surface of the magnet. You can choose it according to your actual usage.
- If you use this magnet to attract to a steel surface, you can simply choose the N/S pole parallel to the countersunk hole.
- When you are planning to use these magnets to attract to each other, you need purchase the direction parallel to the countersunk hole with half N/S half S/N.
- If you plan to use these countersunk magnets to attract to your own magnets, you need buy the opposite pole to match them up.
Besides Ni+Cu+Ni triple layer plated, we can make rubber coated countersunk magnet, epoxy countersunk magnet and plastic coated countersunk magnets.
