NdFeB Permanent Magnet

Products details:

NdFeB Permanent Magnet production process:

Neodymium magnets are actually composed of neodymium, iron and boron (they are also referred to as NIB or NdFeB magnets). The powdered mixture is pressed under great pressure into molds. The material is then sintered (heated under a vacuum), cooled, and then ground or sliced into the desired shape. Coatings are then applied if required. Finally, the blank magnets are magnetized by exposing them to a very powerful magnetic field in excess of 30 KOe.

Neodymium block magnet, also known as rectangular magnet, square magnet or bar magnet, compared with disc magnet, block magnet is not as commonly used as disc magnet, but their straight line and clean edge offer a pleasing and different visual appearance, what's more, it provides a bigger surface area than disc magnet of same diameter.

Block magnet is usually magnetized with north and south pole on opposite square faces, also a multi poles magnetized block is possible with a new magnetizer machine.

Key Advantages of Neodymium Magnet:

• Neodymium Magnet are the most powerful commercially produced magnets.
• Neodymium Magnet have a higher Maximum Energy Product, (BH).max, which can easily reach 30 MGOe and even goes up to 50 MGOe.
• Neodymium Magnet can replace SmCo magnets in most cases, especially where operating temperature is less than 80 degrees Centigrade.
• Neodymium Magnet has very high strength.
• Relatively low cost.
• Compared to Alnico and SmCo magnets, relatively easy to machine

Using:

Home Improvement, Industrial Equipment, Electronics, Healthcare & Medicine, Jewellery, Automotive, Arts & Crafts, Hobby & Science Projects etc.

Notes:

All magnets are fragile and may snap when collide into each other or a steel. If not usecarefully, they will be broken. If handled correctly, they will last for a lifetime
