Product Details

 

Custom Permanent Strong Disk NdFeb Magnet , N35 / N52 Sintered Neodymium Magnets

 

 

Product Description & Specification:

 

Sintered Neodymium (NdFeB)magnets are also referred to as “neo” magnets. They are particularly suitable for high volume production in a wide variety of shape and size. Precise dimensional control is achieved in machining processes.

 

  • Sintered NdFeB magnetic performance is widespread,and big various from different grade,Br:10.4~14.8KGs,Hci:14~35KOe,Bhmax:26~53MGOe.
  • Due to  NdFeB is corroded easily,coating is a necessary process.Electro plating,electrophoresis epoxy and Passivation are often used.Zn,Ni,Ni-Cu-Ni.
  • Salt spray testing :24~200 Hours Max.
  • Working temperature:80°C~230 °C.
  • Due to NdFeB is so brittle,wall thickness need be more than 0.8mm.
  • Max Magnetizing thickness is about 55mm.
  • Tolerance:+/-0.05mm or tighter.

  • Any other payment terms,we can talk over them.

 

2. Sample fee?Delivery date?Shipment?

  • Sample fee: If it is commonly used specifications of the products and our warehouse have inventory, we can provide you with free samples;      Customized specifications of the products, we need a certain amount of sample fee to control the cost of material.
  • Delivery Date:  It's according to the contract,If for any reason there is a delay, we will contact you with an estimate of the revised delivery date.
  • Shipment: We always use DHL Courier company.Fed Ex,EMS etc.,we can talk over this.

 

3. What’s the delivery time?

  • Small order, normally it is 7-15days.
  • If quantity  order, special products, busy production season, then please kindly contact our sales person.

 

4. Will magnets lose their power over time? 

Do lose a very small fraction of their magnetism over time. But if elect the wrong materials and exceed the max work tempreture,magnet will lose magnetism forever.
