Alnico magnet is an alloy composed of metal aluminum, nickel, cobalt, iron, and other trace metal elements, which is widely used in various instruments and other high-temperature applications due to its excellent properties. Although Alnico magnets are very useful, they can cause some trouble if they are not handled properly. Therefore, in this article, we’ll look at the hazards of Alnico magnets. Before using Alnico magnets, please pay attention to the following items and remember that safety first!
The Danger of Breaking or Chipping
Certain types of Alnico magnets can be very powerful. If you place two magnets close to each other, even small magnets will jump together. This is the most common cause of damage to Alnico magnets, and one or both magnets may break.
Because of the great force exerted by the Alnico magnets, chips may fly into someone’s eyes at a very high speed. Thus, we recommend that you wear protective goggles when handling multiple Alnico magnets. In addition, chips and broken Alnico magnets can also be very sharp, so we recommend that you treat them with care like broken glass.
Danger for Children
Young children should always be supervised when they are handling or playing with Alnico magnets. And those young children who might swallow magnets should always stay away from them.
If multiple magnets are swallowed, they may jam and squeeze the digestive tract, causing severe swelling and even life-threatening, requiring surgery. Since AlNiCo magnets are often large, they are more likely to cause suffocation. Since larger Alnico magnets may cause skin pinching, so always keep the magnet out of the reach of unattended children.
Crushing, Blood Blisters, and Cuts
If the larger Alnico magnets are close enough together, they can generate surprising forces. Fingers may be caught between them quickly, causing blood blistering or cuts. Therefore, we recommend that you wear gloves and take extra care when handling large magnets such as Alnico magnets.
Magnetically Sensitive Items
We suggest that you should keep a safe distance (at least 20 cm) between the Alnico magnet and all objects that may be damaged by the magnetic force. Mechanical watches, pacemakers, CRT monitors and TVs, credit cards, floppy disks, and other magnetic storage media (such as videotapes) are all susceptible to strong magnets (such as Alnico magnets).
Cutting or Drilling Alnico Magnets
Alnico magnet can be fixed with adhesive or in some cases can be fixed with countersunk screws. This kind of magnet is very hard and fragile and can be cut using abrasive wheels and carborundum grinding wheels and coolant.
