Description

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.

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.

High Speed Door

High speed shutter door is a rapid operating, anti-crash shutter door for indoor application . The most advantage of this door is that the opening/closing speed can reach to 0.6-1.8m/s, really fast action a lot than tranditional rollling shutter door. short opening and closing times reduce cooling loss, avoid airflow and enable a smooth operating procedure. They can also be designed in larger dimensions for the mining and aircraft industries.

High speed door can be easily installed, economical,quiet and efficient with electromechanical drive.

This door quickly though in/out open gate, ideal for warehouses,factories, hangars use, widths can be from 2m to 20 meters.

The material of this door are variety: PVC curtain to keep the insdie clean, heavy duty aluminum door with wind-resisitant function can wrok in heavy windy weather, and also the freezer door can be used in cold warehouse or somewhere like that.

Including models are:PVC High Speed Door, Aluminum Spiral High Speed Door, Self-Recovery repair door, Cold Storage Room Fast Door.
