Product Details

NdFeB Permanent Magnet

 

NdFeB Permanent Magnet Features:

 

NdFeB magnet is an alloy magnet made from Nd,Fe,B and other metal elements,which has the high remanence,high coercive force,high energy and high performance/cost ratio.The highest magnetic properties is from 33MGOe to 52MGOe,and we are able to control the magnetic properties within the range as you demanded,like SH,UH,EH such high stable properties could be produced as per your industrial application.

We focus on Sintered NdFeB magnet and develop it under experienced engineer and passionate&studious sales team.

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.

It’s not rocket science. You want strong magnets. Powerful magnets.

But you need durable magnets.

The truth is, neodymium metal is brittle. Make one mistake and SNAP, you could have dangerous shattered metal shards flying through the air.

Your safety is our top priority. So fragile N52 magnets aren’t going to cut it.

- Our N45 Neodymium Magnets are Stronger, Thicker, and Less Likely to Break -

With the perfect balance of strength and durability, our N45 industrial grade neo magnets are triple coated in Ni-Cu-Ni (Nickel-Copper-Nickel). This coating creates a lustrous, smooth, rust-resistant finish that won’t corrode or scratch your fridge.

Designed and built to last a lifetime with high resistance to demagnetization. So you can use them over and over again – for any project or need.

Popular Uses for Our Magnets:
✓ Refrigerator magnets that won’t slide down
✓ Crafts, Science experiments, DIY projects
✓ Hang tools, jars, signs
✓ Secure window or shower curtains
✓ Hold car, RV or boat cover
✓ Garage, kitchen, office organization, and More!

WARNING: Neodymium Magnets are very strong. Keep away from children and pacemakers.
