Aluminum-Nickel-Cobalt magnets are used extensively in aerospace applications, automotive, consumer goods, and medical devices.Sintered Alnico magnets has marginally lower magnetic properties, but better mechanical properties, than cast Alnico. Both are hard and brittle materials. They require skillful machining that is best performed on specialized equipment.

Alnico  (Aluminum-Nickel-Cobalt) Magnet is high-energy permanent magnet, which posses high flux density, high coercive, high energy product and extreme stability for temperature changes. It exhibits good resistance to demagnetization, stability in high temperatures and excellent conduction.

Advantages for using Alnico:

*Excellent temperature characteristics
*Capable of working at a wide range of temperature up to 550 degrees centigrade.
*High field strengths at medium prices
*Easy of magnetizing, The lower coercive force of Alnico makes magnetizing a simple matter in most cases
*Compatible with most painting or plating systems (including nickel and copper)

Charasteristics:

*Suitable for small volume magnet with complex shape;
*Compact crystal, high intensity;
*Regular shape, precision size;
*Even elements, stable performance;
*Suitable for compound magnet;
*Excellent temperature stability (temp. coefficient of Br is the smallest among all of the other permanent magnets.)

Alnico permanent magnet have three kinds of different production process: casting , sintered , bonded.

Cast alnico magnet production process:

Incoming inspection----Mixing----Melting---Casting---Heat Treatment---Tumbling---Magnetic Inspection---Machining---Cleaning and Drving---Machining Inspection---General Inspection---Package---Storage

Sintered alnico magnet production process:

Incoming inspection---Mixing---Powder---Pressing---Sintering---Heat Treatment---Mangentic Inspection---Machining---Cleaning and Drving---General Inspection---Package---Storage

Magnetic properties:

Price Advantage:We take The centralization, scale production, reduce the cost . In the same quality products,our price is cheaper than industry average.

Export Standard Cartons are supplied with foam well protected. We can make the packages according to customer's request. Sea packages and air packages are both available
