Product Description

Ferrite(Ceramic) Magnet is manufactured from oxide materials using powder metallurgical process. Ceramic magnet is most widely used because of its low cost, high-energy, good electric insulation and excellent resistance to demagnetization. The most common type of ceramic magnets are anisotropic strontium, anisotropic barium and isotropic barium magnet.There are two manufacturing process for ferrite magnets:
Dry Process&Wet Process.By dry process, can produce isotropic & anisotropic magnets;by wet process, only anisotropic magnets can be produced.
Isotropic ferrite magnets are not oriented and can be magnetized in any direction;anisotropic ferrite magnets are different, they are all oriented in the manufacturing direction, and should be magnetized in the direction of orientation. For dry process,the tool can be changed and developed easily,while for wet process,it is complicated to change the tool and the tooling charge is much higher. At present, we have put our emphasis on arc segment magnets for electric motors,disc magnets and block magnets for special applications .

Product overview:

Permanent ferrite magnet shape:
 

Sintered ferrite (ceramic) magnets are also available in forms of isotropic and an-isotropic. The magnetic properties

of isotropic ferrite are the same in all directions, therefore they can be magnetized in any pole arrangements.

An-isotropic ferrite magnets, on the other hand, can only be magnetized in the direction they are oriented during production,but they have much higher magnetic strength than isptropic ones.

FAQ:

1. Do SCG Company supply permanent magnets with standard sizes?

No. SCG accept OEM considering our many years experience in serving our customers, because different have different requirement in grade, size, coating, tolerance etc.

 

2. Can I have a free sample of your magnets?

SCG will provide free sample if the sizes in stock, otherwise, we will charge the sample cost which will be returned to our clients after the order confirmed.

 

3. How long will it take to receive your price quotation?

Usually it takes 1- 2working days.

 

4. What is your lead-time after I place a purchase order?

Usually take 1 week for usual size. If it is needed to make a mould, it may take a little longer.

 

5. What kind of payment do you accept?

Company's checks, TT, LC, Paypal, Western Union
