Alnico, Ceramic, Rare Earth, Rubber and Neodymium Magnets.
Alnico Magnets, excellent temperature stability.
bullet
Ceramic Magnets, excellent in peak magnetic product and greater resistance to demagnetization.
bullet
Rare Earth Magnets, higher energy product values and greater temperature stability.
bullet
Rubber Magnets, multiple magnetization pattern concentrates magnetic strength on one face.
bullet
Neodymium Magnets, latest development in high energy magnets, less chipping and cracking than Rare Earth Magnet.
