Product Details

Sintered AlNiCo High-Energy Permanent Magnets

We have the fixed Long-term cooperation factory. Which is mainly produce kinds magnet. We have invested much funds for some equipment, for example injection molding machine.
And Our technology is introduced from Japan and Germany. The major technical leader in our factory is from Japan and has been studying this field for over 15 years. Wish our best technology can solve your production problems.

1. Product Details

ALNiCo permanent magnetic material: ALNiCo is an alloy made from Aluminum, Nickel, Cobalt, Iron and a few other rare metal. It employes a casting process for it manufacturing , thus it has good processablity. The casting ALNiCo magnets has the lowest reversible temperature coefficient, its working temperature can be above 600. ALNiCo permanent magnets are widely used in instruments and other areas.


Material: Aluminum, Nickel, Cobalt, Iron and a few other rare metal.
 
Shape:  Cylinder, Block, Disc,Countersunk, Segment, Trapezoid, Irregular shapes and more. Customized shapes  are available

Tolerance in size: +/-0.1mm ( +/-0.05 available)
 
Type of coating: Ni-Cu-Ni, Nickel, Zn, Gold, Silver, Copper, Epoxy, Chemical, PTFE, Parylene, Everlube, Passivation and more.
 
Grade:LNG10.LNG12.LNG13.LNG18.LNG37.LNG40.LNG44.LNG52.LNG56.LNGT60.LNGT72.LNGT88.LNGT36J.LNGT52J

Direction of magnetisation: Axially magnetized or Diametrically magnetized

Quality control: ISO90001, ISO/TS16949,ISO14001,OHSAS18001,ROSE,ROHS

Features:
An ideal material in high temperature applications, which has high operating temperature up to 550°C and above, with excellent corrosion resistance. They can become partially demagnetized if they come in contact with other ferrous materials, special care is required during handling and storing. 
Usually cast and grinded during production, they are available in various grades depending on its application. Others such as sintered Alnico have lower magnetic properties but offer higher mechanical characteristics.
