Samarium Cobalt Block Magnets
Samarium Cobalt block magnets are ideal for applications where consistent performance is required at extreme temperatures, offering excellent resistance to demagnetisation and strong magnetic force relative to their size.
Samarium Cobalt block magnets are preferred for specialised uses such as high-performance motors, where neodymium block magnets lose strength at high heat. They are also used in sensors for measuring temperature and pressure across industries like mining, refining, and agriculture. Additional applications include medical implants, tools, computer disc drives, and hobby or craft projects where smaller, durable magnets are required. If a more powerful magnetic block is needed and temperature stability is not a concern, see our Rare Earth Blocks.
FAQ
What are Samarium Cobalt block magnets used for?
Samarium Cobalt block magnets are widely used in aerospace, defence systems, medical devices, and high-temperature motors. Their strength, compact size, and stability make them ideal for demanding industrial environments.
How do SmCo block magnets perform under high temperatures?
SmCo magnets operate effectively at temperatures up to 300°C and beyond. Unlike neodymium magnets, they maintain magnetic performance without degrading in sustained heat.
Are Samarium Cobalt block magnets corrosion-resistant?
Yes. SmCo magnets are naturally corrosion-resistant and do not require coatings or plating, making them suitable for harsh or corrosive environments.
What are the advantages of using SmCo block magnets over other types?
The key advantages are thermal stability, strong magnetic force, and resistance to oxidation and demagnetisation, making them highly reliable in extreme conditions.
