Strong Samarium Cobalt disc magnets (SmCo). We offer a wide selection of samarium cobalt discs, ranging from 2 mm to 25mm in circumference and height. These samarium cobalt magnetic discs are made of an alloy of samarium and cobalt. Their strength is similar to neodymium magnets. But what really makes Samarium Cobalt Magnets one of the best options for use in appliances is their ability to retain their magnetic strength. For example, samarium cobalt disc magnets can function in applications that run on extreme high or low high temperatures.
If you need magnetic discs that aren’t prone to corrosion or oxidation, then these rare earth magnets will deliver. There is no need to add a protective coating. However, we advise you to be very careful with them because they are brittle and can easily crack or chip. We provide magnets in various custom grades and sizes.
