Description:
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.

As a member of non-rare earth metallic permanent magnetic material. AlNiCo magnets emerged in 1931 and once dominated the permanent magnet industry due to the strongest magnetic performance before the rare earth permanent magnet was born. The composition of alloy magnets is typically 8-13wt% Aluminum, 13-28wt% Nickel, 5-24wt% Cobalt, and the balance is Iron. Furthermore, alloying element like Copper, Titanium, and Niobium is added to matrix phase to promote the enhancement of needle phase, thus improve intrinsic coercivity. AlNiCo magnets can be classified to cast magnets and sintered magnets according to the manufacturing technology. Even to this day, AlNiCo is still serving for some specialty application due to its incomparable temperature characteristics.

Packing:
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.
Shipping:
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.
