Neodymium Magnets are the most widely used Rare Earth magnets. Some typical applications include tape recorders, alternators, pacemakers, biasing applications, flow meters, gyroscopes, and linear actuators. We stock Neodymium blocks and plugs in a variety of sizes and grades for immediate shipment and also provide custom cutting. Corrosion-resistant nickel-plating from .0004 inch to .0008 inch thick and heat-resistant grades are available. Nickel plating helps protect against corrosion. For high-temperature service, Neodymium Grade 30SH can safely be used at operating temperatures up to 300° Fahrenheit (149° Celsius) – depending on the magnetic circuit. Call for technical advice.

Samarium Cobalt Magnets produce energy rivaling that of Neodymium. Typical uses include many hi-tech applications, such as computers, electronics, switches, and automotive “under-the-hood”
applications, where elevated temperatures apply.

Samarium Cobalt magnets are extremely hard and brittle and should be protected from shock and mechanical forces in their application when handling. They resist corrosion and retain most of their energy up to 575° Fahrenheit, making them ideal replacements for Alnico when high temperature use or miniaturization is required.

Samarium Cobalt 18 and 22 were the first Samarium Cobalt grades manufactured and are derived from nearly pure Samarium and Cobalt. Samarium Cobalt 26 has an even higher temperature stability than the 18 and 22 grades and is especially suited for applications demanding high energy in high-temperature environments.
