This listing includes a top quality disc AlNico magnet which is made of AlNiCo 7 material. This magnet is 3/4" diameter x 1/4" thick and magnetized through 1/4" so the N and S poles are on flat surfaces. This magnet has a holding of 3.34 lbs.
AlNiCo magnet has extrodinary temperature stability than the other types of magnets so it is mostly used in high temperature toolings or oil field applications where high temperature is present. AlNiCo magnet is also used as guitar pickups.
Generally speaking, AlNiCo magnets are more fragile than neodymium magnets. There is no coating for this magnet.
