Frequently Asked Questions
Q1: What is the main difference between SmCo5 and Sm2Co17?
SmCo5 is composed of one part Samarium to five parts Cobalt and offers a BHmax of 18-22 MGOe. Sm2Co17 (two parts Samarium to 17 parts Cobalt) is stronger with a BHmax of 24-32 MGOe and has better thermal stability up to 350°C.
Q2: Why choose Samarium Cobalt (SmCo) over Neodymium (NdFeB)?
SmCo magnets are chosen for their superior performance at high temperatures (above 150°C) and their excellent corrosion resistance, which often eliminates the need for coating, unlike NdFeB magnets.
Q3: Do SmCo magnets require protective coating?
Generally, SmCo magnets are highly resistant to oxidation and do not require coating. However, for specialized medical or extreme saltwater environments, nickel or gold plating can be applied.
Q4: Are SmCo magnets brittle?
Yes, like most rare-earth magnets, Samarium Cobalt is brittle. It should not be used as a structural component and should be handled carefully to avoid chipping or cracking.
Q5: What shapes can be customized for SmCo magnets?
We can manufacture SmCo magnets in various geometries including discs, blocks, rings, arcs, and intricate custom designs tailored to specific motor or sensor requirements.
Q6: Can SmCo magnets be used in a vacuum?
Yes, because SmCo magnets have high resistance to corrosion and do not outgas (especially when uncoated), they are excellent for aerospace and vacuum applications.
