Product Description

Electro Permanent Magnetic Chuck Square Powerful Magnet with Hole



What Is Alnico?

Excellent temperature stability, high residual induction, and relatively high energies.

Alnico is a combination of Al (aluminium), Ni (nickel), and Co (cobalt).

This development and introduction of Alnico meant that expensive electromagnets could be replaced with permanent magnets in essential devices like motors and generators.

Alnico magnets are permanent magnets that are primarily made of aluminium, nickel and cobalt.

AlNiCo magnet is composed of Aluminum, Nickel, Cobalt, and a few transition metals. They have excellent temperature stability, high residual induction, and relatively high energies. AlNiCo magnet may be manufactured in complex shapes, such as horseshoes, which is otherwise not possible with other magnet materials. They represent the most versatile magnets available.

Manufacturing Process:
Alnico magnet is manufactured through either casting or sintering processes. Cast magnet is manufactured by pouring a molten metal alloy into a mold and then further processing it through various heat-treat cycles. The resulting magnet has a dark gray exterior appearance, and may have a rough surface. Machined surfaces have a shiny appearance similar to steel. Sintered magnet is manufactured by compacting fine Alnico powder in a press, and then sintering the compacted powder into a solid magnet.


Machining & Tolerance:
Alnico magnet is hard and brittle, and prone to chipping and cracking. Special machining techniques must be used to machine this material. The Standard tolerances for Alnico magnet is +/- 0.1mm for ground dimensions, but sticter tolerances are possible if specially required.


Surface treatments:
The corrosion resistance of Alnico magnet is considered excellent , and no surface treatments are required. However, Alnico magnet is easily plated if specially required.


Magnetizing & Packing:
Alnico magnet requires magnetizing fields of about 3kOe. Because of their relatively low coercivities. Alnico magnet should be packed properly in order to assure that the magnet is not subjected to adverse repelling fields, since this could partially demagnetize the magnet.
Cast Alnico 5 is the most commonly used of all the cast Alnicos. This material is used extensively in rotating machinery, meters, instruments, sensing devices, and holding applications, to name a few.

As the magnets have strong attraction and we will use the spacer to apart the magnets each other in case people will be hurt when take it out. Then, they will be packed in a white box of pieces each, several boxes to a carton.

+By Air: If the goods will be shipped by air, all the magnetic should be degaussed and we will use Iron sheet to shield.
+By Sea: If the goods are will be shipped by sea, we will place a pallet on the bottom of cartons.



Express (TNT, DHL, FedEx, UPS, etc), Air, Ocean.
A: The weight is under 40Kgs, we recommend to send them in shielding boxes to you by Express.
B: The weight is between 40Kgs-100Kgs, it can be sent by Express or Air.
C: The weight is over 100Kgs, we recommend to send them by Ocean.
