What is Alnico?

• Alnico is an alloy containing Aluminium (Al), Nickel (Ni), Cobalt (Co) hence named Alnico.   
• Alnico alloys make strong permanent magnets, and can be magnetized to produce strong  magnetic fields .  
• Alnico magnets are characterised by excellent temperature stability, high residual induction and high energies.

• They are manufactured by either   casting or sintering  process.
• Cast magnets  can be manufactured in complex shapes, such as horseshoes, not possible with other magnet materials. 
• Sintered Alnicos  offer slightly lower magnetic properties but better mechanical characteristics than cast Alnicos.
• 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.

 

ALNICO MAGNETS
2. For optimum performance of Alnico 5, the magnetic length should be approximately 5 times the pole diameter or equivalent diameter. For example, a 0.250"" diameter magnet should be about 1.250"" long. 3. Because of its higher coercivity, Alnico 8 may be used in shorter lengths and in disc shapes. Alnico has a low coercive force, and is easily demagnetized if not handled with care.

Packing information:

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.
