Product Details

Products Introduction:

Alnico magnets are made of aluminum, nickel, cobalt, copper, iron and other materials. We can manufacture cast and sintered alnico  permanent magnets  in a variety shapes including horseshoe, U shape, bar, block, disc, ring, rod and other customized shapes, grades like FLN8-FLNGT42, LN9-LNGT72, or alnico2-alnico9,magnetized through thickness or diameter. Customers usually order uncoated alnico, several customers requested NiCuNi plating, yes, we can do it, but as it has weak adhesion to plating, NiCuNi plating might flake off if not handled properly. 


Cast Alnico Magnets 

Cast alnico magnets are made by pouring melted AlNiCo material into a mold, and then heat and cool the solidified blank. Cast AlNiCo are mainly manufactured into shapes of disc, block and ring, and are characterized by low temperature coefficient, high dampness, oxidation and temperature resistance, as well as the stability of magnetic performance..

Sintered Alnico Magnets

Sintered Alnico magnets are produced by powder metallurgy technology, which enables the production of sintered alnico into various complicated, light, thin and tiny shapes....

Production Process

Raw Materials – Burdening – Melting – Cleaning – Sorting - Grinding – Rough Inspection – Heating Treatment – Magnetic Inspection – Finish Machining – Cleaning Drying – Finishing Test – Finished Goods Inspection – Packing – Final Shipment Inspection – Shipment

Cast alnico & Sintered alnico

According to different production process, alnico magnets can be divided into sintered and cast. Compared with sintered magnets, cast alnico magnets have following advantages.

1. Cast alnico can be processed into different sizes and shape, while sintered alnico magnets are limited to small sizes.

2. Cast alnico magnet is slightly better than sintered alnico magnet in magnetic performance.

3. Cast alnico has the lowest reversible temperature coefficient.


Cast alnico magnets are mainly applied in automotive parts, instruments, electro-acoustic, electrical, teaching equipments, aviation and military areas. Sintered Alnico magnets are widely used in fields of instrumentation, communications, electronic, magnetic switches, sensors and others. 


Given the low coercive force of alnico permanent magnet, in order to avoid irreversible demagnetization or disorder of magnetic flux distribution, alnico magnets shall be strictly kept apart from other magnetic materials in actual application or shipping process, especially neodymium magnet material.
