Dry Pressing Ferrite powder  
UMDS series Anisotropic Strontium Dry Pressing Ferrite Magnetic Powders are suitable for producing magnets by dry pressing. According to the customers requirement , such products can be classified as isotropic powder and anisotropic powder , anisotropic powder has better orientability.

Manufacture summary:

a.  The necessary secondary additives have been added into the powder during the grinding process.Customers shall only add proper quantity of binders and lubricants.The powder must pass through 120 mesh sieve before pressing,so as binders to be uniformly distributed for better orientaton.
b .Please take care of the cleaning of the equipments.Any other materials and impurity should not be mixed into the powder.
c. During pressing,the pressure required is >=5000N/cm2,and the magnetic field density is >7000 Oe(560KA/m).
d. The sintering temperature for reference is 1220 to 1270 .Please note that the proper sintering temperature should be defined in accordance with the status of the sintered sample pill.
