Neodymium magnet is a permanent magnet made from an alloy of neodymium, iron and boron. NdFeB magnets are widely used in various fields, such as motors, speakers, electric generators etc. Besides, the neodymium magnet is the strongest type of permanent magnet commercially available.

Sintered NdFeB magnets are the most powerful commercialized permanent magnets available today, with maximum energy product ranging from 26 MGOe to 52 MGOe. Nd-Fe-B is the third generation of permanent magnet developed in the 1980s. It has a combination of very high remanence and coercivity, and comes with a wide range of grades, sizes and shapes. With its excellent magnetic characteristics, abundant raw material and relatively low prices, Nd-Fe-B offers more flexibility in designing of new or replace the traditional magnet materials such as ceramic, Alnico and Sm-Co to achieve high efficiency, low cost and more compact devices.

Advantages
*Extreme strong Br Resident induction.
*Excellent demagnetization resistance capability.
*Good Price relative to its high magnetic properties.

The above-mentioned maximum working temperature of magnet is changeable due to the ratio length and diameter,surface coating and environmental factors.


FAQ
1. MOQ: less quantity is acceptable for your easy start of business
2. Sample lead time: 15-20 days.
3. Port: Shanghai, Ningbo, China any port.
4. Fast Delivery: when you choose the item and decide your design, we can produce it as fast as possible.
5. If you would like to make an enquiry, how can you contact us?

6. The way of identify the pole of magnet:
The easiest way is to make a dot on the North or South or both Poles. If you need, we can make the dot as your requirement

7.Is one pole stronger than the other?
No, both poles are equally strong

8.Which is the strongest type of magnet?
Neodymium (more precisely Neodymium-Iron-Boron) magnets are the strongest permanent magnets in the world.

9.Can you supply BH Curves, or Demagnetization Curves for your magnets?
Yes, we've offered Demagnetization Curves for our most common Neodymium magnet grades right here.


10.Will my neodymium magnets lose strength over time?
Very little. Neodymium magnets are the strongest and most permanent magnets known to man. If they are not overheated or physically damaged,
neodymium magnets will lose less than 1% of their strength over 10 years - not enough for you to notice unless you have very sensitive measuring equipment.
They won't even lose their strength if they are held in repelling or attracting positions with other magnets over long periods of time.

Features

Constant speed, achieving synchronous speed.
High power factor: A well-designed motor can achieve a power factor close to the value of 1.0.

Compact size, lightweight, and low noise.

High efficiency: During normal operation, there is no copper loss in the rotor. The high power factor results in a smaller rotor current and reduced copper losses in the rotor windings.


The motor's speed is directly proportional to the frequency, simplifying the control system.

The motor can be designed with multiple stages and low-speed high-torque capabilities, eliminating the need for a gearbox and enabling gearless transmission.

Wide speed range, with a high-speed design that can reach up to 10,000 revolutions per minute (rpm).

The Incinerated scrap or E46, is the by-product derived from the reprocessing of incinerated domestic waste.
After the combustion process, the furnace output (IBA Incinerator bottom ash) is firstly washed, magnetically separated and screened to separate any no ferrous material.

At a visual inspection, the material is fragmentized, with iron and steel parts, resulting partly cut or in shredded form.
The stock appears heterogeneous and contains all kind of cut or dismantled steel parts such as sheets, bars, frames, wires, bolts and other iron/steel household residues.

The incinerated scrap is eventually oxidized, due to the thermal and cooling treatments, that the material has been submitted to. The burnt scrap also contains minor slag parts, ash and iron oxide, due to the recovery process.
Such components are inherent and adhere to the scrap surface. The total impurities, can be sorted, but not fully removed.

The consignment does not contain any type of arms, ammunition, mines, shells, cartridges, radioactive contaminated, or any other explosive material in any form either used or otherwise.

The collected stock, is stored in open air, on cemented flooring. It can be loaded loose in 20â?? heavy duty container.

Please feel free to contact us for further details.

Pularin:
Foot ball shaped 60 atoms of carbon at edges is layed in pularin.Pularin atoms are arranged in ball.
Each atom is called Bucky balls and tubes are called Bucky tubes or Nano tubes.Each nano tube is 1 to 7 nm diameter i.e 1nm=50000 part of a hair sting.
