Product Description
| AlNiCo magnets are composed of Aluminum, |
| Nickel,Cobalt, and a few transition metals. They |
| have excellent temperature stability, high residual |
| induction, and relatively high energies. AlNiCo |
|
magnets may be manufactured in complex shapes, |
| such as horseshoes, not possible with other |
| magnet materials. They represent the most |
| versatile magnets available. |
|
Manufacturing Process |
|
Alnico magnets are manufactured through either |
| casting or sintering processes. |
| Cast magnets are 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 magnets are manufactured by compacting |
| fine Alnico powder in a press, and then sintering |
| the compacted powder into a solid magnet. |
|
Machining & Tolerance |
|
Alnico magnets are hard and brittle, and prone to |
| chipping and cracking. Special machining techniques |
| must be used to machine this material. |
| The Standard tolerances for Alnico magnets are |
| +/- 0.1mm for ground dimensions, but sticter |
| tolerances are possible if specially required. |
|
Surface treatments |
| The corrosion resistance of Alnico is considered |
| excellent , and no surface treatments are required. |
| However, Alnico magnets are easily plated if |
| specially required. |
| Magnetizing & Packing |
| Alnico magnets require magnetizing fields of about |
| 3 kOe. Because of their relatively low coercivities, |
| Alnico magnets should be packed properly in order |
| to assure that these magnets are not subjected to |
| adverse repelling fields, since these could partially |
| demagnetize the magnets. |
