Alnico Magnets, excellent temperature stability.

Ceramic Magnets, excellent in peak magnetic product and greater resistance to demagnetization.

Rare Earth Magnets, higher energy product values and greater temperature stability.

Rubber Magnets, multiple magnetization pattern concentrates magnetic strength on one face.

Neodymium Magnets, latest development in high energy magnets, less chipping and cracking than Rare Earth Magnet.
