Samarium cobalt magnet is a type of permanent magnet made from an alloy of samarium, cobalt and iron. This makes them one of the strongest magnets that can be used for domestic and industrial applications. If you need a magnet for high temperature applications, your best choice is Samarium cobalt magnets in Brisbane because of their high magnetic performance.
Samarium cobalt magnets have high magnetic properties but it is only second to the performance of neodymium magnets. A few decades ago, samarium cobalt magnets were the best option for a little strong magnet; however, its price increased significantly. This drove scientists to discover a viable alternative to the samarium cobalt magnets.
However, science also needs to consider economics aside from its principles, laws and theories. The law of supply and demand has led scientists to undertake a research project for a strong permanent magnet that will be more affordable to the market. The rare earth neodymium magnet became a household word during the 1980’s because it packed a lot of power in a very small package. The neodymium magnets took the automotive, robotic and electronic industries by storm.
Neodymium magnets suddenly revolutionized the world of motors because a 20mm square cube has a magnetic field about half a tesla with an order of magnitude that is stronger ounce for ounce compared to the flimsy barium iron oxide magnets.
However the dream of having a perfect magnet for motors became a nightmare. In 2010, there was scarcity and other economic, geopolitical and environmental factors that caused a sudden price hike. By then, the neo-magnets have been so heavily entrenched in human life making the whole worried about the fate of their products. Today, the price of neodymium continues to go up and has skyrocketed by more than 80% since the start of 2017.
Aside from its suitability to high temperature applications, Samarium cobalt magnets in Brisbane do not require surface treatments because it is rust resistant. The Samarium cobalt magnets can maintain its magnetic performance over a wide range of temperatures from 150oC to below absolute zero (-273oC) which makes them ideal for cryogenic applications.
