            [_data_accordion_title] => Advantages and Disadvantages of Samarium Cobalt Magnets 
            [_data_accordion_text] => Samarium Cobalt magnets (SmCo) are a type of rare earth magnet known for their high magnetic strength, high resistance to demagnetisation, and excellent temperature stability. Like all magnets, they have advantages and disadvantages that should be considered when selecting them for use in various applications. Here are some of the advantages and disadvantages of Samarium Cobalt magnets:

Advantages:

High magnetic strength: Samarium Cobalt magnets are known for their exceptional strength and magnetic properties, making them ideal for applications that require high magnetic forces.

High resistance to demagnetisation: They have high resistance to demagnetisation, meaning they can maintain their magnetic strength for long periods of time.

High-temperature stability: Samarium Cobalt magnets are highly resistant to temperature changes, and can maintain their magnetic properties at high temperatures of up to 350°C.

Wide range of shapes and sizes: These magnets can be made in a wide range of shapes and sizes to fit various applications.

Disadvantages:

Cost: Samarium Cobalt magnets are relatively expensive compared to other magnets, such as ferrite magnets.

Brittle: They are brittle and can easily crack or break if dropped or subjected to impact.

Corrosion: They are prone to corrosion and may require coating or plating to protect them from rust and degradation.

Handling: These magnets are extremely strong and can be challenging to handle, requiring care and caution when being installed or removed.

            [_data_accordion_title] => Coatings Available for Samarium Cobalt Magnets
            [_data_accordion_text] => Samarium Cobalt magnets stand out for their exceptional corrosion resistance, a characteristic often attributed to their minimal iron content, setting them apart from Neodymium magnets. Typically, these magnets do not require additional coatings or platings. It's noteworthy that while certain grades within the Sm2Co17 family do contain traces of iron, their corrosion resistance remains commendable, especially if not directly exposed to water. For the majority of applications, a coating or plating is not mandatory. However, in environments with acidic conditions, high moisture, or vacuums, it's advised. For those with specific needs, Goudsmit UK provides specialised coating solutions. Trust in our expertise for prolonged magnet lifespan and optimal performance.

Samarium Cobalt (SmCo) magnets are highlighted for their minimal environmental reactivity, making them highly suitable for sectors such as Medical and Aerospace. Before finalising any design approach, we strongly recommend a thorough empirical assessment of the magnet alloy within its intended operational environment. Notably, when deployed in medical settings, our Samarium Cobalt magnets are often fortified with a parylene coating and further enveloped in a material apt for the specific application.
