Custom SmCo30 & AlNiCo5 Permanent Magnets

Looking for Magnets Use in Measuring Instrument :
For a measuring instrument we need a permanent magnet as illustrated in the accompanying Drawing.



The magnetic material: CoAlNi and SmCo.
The magnet should be completely magnetized in the axial direction.
We ask for an offer for Prototypes of each material.

Magnet Manufacturer China Rare Earth Magnet Limited :
Many thanks for your inquiry.
Could you specify the grades of AlNiCo and SmCo magnets?
Are they Alnico5 and SmCo28?

AlNiCo5 & SmCo28 Permanent Magnet :
Thank you for your request.
The required magnetic material has a high energy density BH, and especially a very good stability at temperature changes is necessary.
The magnet is used at 50 ° C.
Good is AlNiCo5
For the material SmCo28 I find no information on the constancy of the temperature.

AlNiCo & SmCo Manufacturer China Rare Earth Magnet Limited :
Enclosed please check the grade list of SmCo magnets .
The BH max of Alnico material is higher than that of SmCo material.
But the magnetic strength of SmCo magnet is stronger than AlNiCo material.

Magnet Specification:
Thank you for your information.
We now ask for an offer (price and delivery time) for permanent magnets:
Ring Shape, Diameter (outside), Diameter (inside), Height as per drawing
Axially magnetized
We also ask for the information about how you want to pay.
