Product Description

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
1.Compact crystal, high intensity, good chemistry stability, stong anti-corrosion, even elements, excelent and magnetic performance, excellent temperature stability, highest usage temperature reach 500 degree. 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.

Our Advantages

 

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.
