Neodymium Magnets in Gas Applications 20161029

Neodymium Magnets in Gas Applications 20161029
Permanent Magnets Manufacturer China Rare Earth Magnet Limited


Look for High Temperature Neodymium Magnets :
We are a consultant company and we are developing a new product for a customer.
For this new product we need one or two permanent magnets.
We need a magnet with high stability also in high temperature environment; the two main applications
(and product versions) require the following two ranges of temperature:
A: -40 to +100 °C
B: -40 to +150°C
The magnets will stay in gas (Methane or LPG).
The magnets that we are testing (commercial magnets) are neodymium magnets (grade N35), and have the following dimensions: two discs / two rings
Custom Neodymium Disc MagnetsCustom Neodymium ring Magnets
Custom Neodymium Disc Magnets
Custom Neodymium ring Magnets
We are testing them to decide which kind we have to use.
Is it possible to have a quotation for big volumes?
If you need some other details please let me know.

High Temperature Permanent Magnets Manufacturer China Rare Earth Magnet Limited:
We quote the magnets based on N35 for your reference.
Unit price: **USD/pc
Remark:
Max working temperature of Grade N35 is only 80°C.
If you need the magnets work in +100 or +150°C, N35H or N35SH will be better.

Ask for the Price of N35H and N35SH:
Many thanks for your quotation.
It's very clear.
What is the difference in price for grades N35H and N35SH compared to N35?
I'll discuss all these details with the customer and I'll give you a feedback very soon.

Neodymium Magnet Manufacturer China Rare Earth Magnet Limited:
Please kindly check the quote of N35H and N35SH in attachment.
We would be much appreciated if you could give us any feedback.

Ask if the Magnets can be used in Gas Applications:

May I ask you if you can update the quotation based on the attached drawing, please?
The customer asks us to consider different grade. We need to find out a balance between performances and costs to finalize the project.
In your opinion is it possible to use this kind of magnets in gas applications (Methane and LPG)?

Neodymium Permanent Magnet  Manufacturer China Rare Earth Magnet Limited:
Our engineers inform that the magnets can work in gas application, as long as they do not expose to humid or acid environment.
Please confirm if the magnets will work in dry conditions. If not, you will have to consider changing the coating.

Neodymium Magnets for iPhone / iPad / Smart phones covers 20161013

Neodymium Magnets for iPhone / iPad / Smart phones covers 20161013
Permanent Magnets Manufacturer China Rare Earth Magnet Limited


Neodymium magnets  are more and more used in covers or housings for iPad, iPhone and other branded smart phones by manufacturers.
Neodymium Permanent Magnets for Mobile Phone Cover


Neodymium permanent magnet can be used as magnetic button on the edge of leather housing, and can be used inside the back cover to enable the back cover attach to the phone firmly.

The strong rare earth magnets don't only bring great convenience to human's work and life, but also stimulate people's innovative concept and ideas.

Smart cover designed by Apple broke through the traditional thinking mode and design of leather cover, silicon rubber case and protective jacket. This protection cover looks more like a book cover.
The 3 main special functions of Smart Cover are
(1) Automatic alignment of magnetic axis;
(2) Open the cover the device automatically activated, close the cover the device enters sleep mode automatically.
(3) The cover can be folded into a triangle, used as the support of the device.

Smart Cover

Using magnetic field viewer, many small permanent magnets  can be found at the edge of Smart cover and Ipad body. A large number of NdFeB magnets at the side of Smart Cover is to guarantee the stability of the support, and the circular magnet in the red circle is just the secret of auto sleep function.

If you put a strong neodymium magnet close to this position of iPad, the system will also self-closing screen and enter sleep mode.
Neodymium Permanent Magnets for iPad Cover

At the other side of the device, the corresponding magnets are also found. These neodymium NdFeB permanent magnets ensure the function of automatic alignment of Smart Cover. If you put Smart Cover near the iPad optionally, the cover and the iPad can self alignment automatically.

Magnetic Assemblies Manufacturer China Rare Earth Magnet Limited:
 Permanent Magnetic Assembly
Our engineers review the drawings and inform that price will be expensive, if neodymium magnets are used.
Therefore we quote both permanent magnets based on samarium cobalt magnets.

Also, on drawing of door magnets, it states that the magnets should be coated with black zinc.
But black zinc is not used in industry currently, because it is not environmental-friendly.
So we quote the magnets based on coating with black epoxy and black nickel.
Please kindly check the quote below.
