SmCo₅ (1:5 Series)

The SmCo₅ series represents the original rare-earth cobalt magnet composition, known for its excellent corrosion resistance and reliable magnetic output . With a maximum operating temperature of 250°C, these magnets offer a good balance of magnetic properties and machinability . Due to the absence of iron in their composition, SmCo₅ magnets provide superior intrinsic corrosion resistance, making them ideal for applications where protective coatings are difficult to apply . Their slightly better ductility compared to the 2:17 series allows for greater flexibility in machining complex shapes and thin-walled components . Tecomag SmCo₅ magnets are widely used in sensors, precision instruments, and magnetic couplings where long-term stability is critical .
