Small Block AlNiCo Permanent Magnets 20180206

Inquire Small Block Magnets:
Magnet specification:

Parameter
a: 4mm
b: 4mm
L: 1.5mm
Magnet Parameter:
Br: 1220 mT
Temp. Coeff. of Br: -0.11 %/°C @20~100°C
Could you check the manufacturing feasibility of this magnet?
If yes, please update us with quotes.

Small  Permanent Magnet  Manufacturer China Rare Earth Magnet Limited: 
Thanks a lot for your inquiry.
There are some points I would like to confirm with you.
What's the material of this magnet? Is that NdFeB material? If yes, could you please advise us what's the grade of this magnet?
In addition, in your drawing, the size of L should be the longest, but its size is 1.5mm. Could you please confirm it?
By the way, could you please tell us which quantity you need?
After receiving the information, I will inquiry our related dept if it can be produced or not.

Magnetic Materials: 
Basically we are looking for magnet with better temperature coefficient. If we go for NdFeB we will have -0.12 %/°C temperature coefficient.
Alnico and Smco is having better temperature coefficient, as shown below. So, better you suggest us magnet in Alnico or Smco material.

Though size of L is long in drawing, but its actual value is 1.5mm.
Initial volume will be 10,000pcs per year and the mature volume over 3 years will be 25000pcs.

AlNiCo Magnets   Manufacturer China Rare Earth Magnet Limited: 
We provide quotation based on Alnico permanent magnets which have a better temperature coefficient. Please check it.
