Rare earth element Samarium mixed with Cobalt is an excellent magnet that found its way to magnetic jewellery decades ago. Gem & jewellery industry has pounced on it for its dual function: its magnetic capability and anti-rusting feature. Read more…
Samarium Cobalt magnet is referred to by its short form name as “SmCo Magnet” or in much more user friendly term of “Samco”. Introduced in 1970 Samco is the second powerful man- made magnet after Neodymium. It is bio-compatible despite the scare over its constituent alloy of Cobalt. The mixture of Samarium with Cobalt has all the pluses the gem & jewellery industry is looking for: Samarium is hard and brittle Cobalt is lustrous and shatter-proof. Both are hypoallergenic and have excellent anti-corrosive capability. The finished product can fit in many types of jewellery wear including bracelet, amulet, choker and anklet.
Price and performance wise Samco ranks second to Neodymium. Yet in terms usability Samco scores well over its competitors in the magnet fraternity. It is the only magnet that can balance size, performance and price at even keel. May be for this reason Samco is used in aerospace industry where performance, size and price are parts of an equation. Added feature of Samco is that it can function under adverse conditions and high operating temperature rising as much as 350 degree Celsius.
Magnetic Flux Density which is the measure that tracks the continuous production of magnetic power is ticked at 10,500 Gauss. Due to this higher performance even quarter inch thick Samco magnetic strip would be more than sufficient for a bracelet.
Naturally Samco does not lose magnetism over the years and has higher resistance to external magnetizing fields. This we call as Coercive Magnetic Field Strength. For Samco this magnetic field strength is slated high. Consequently even if Samco is exposed to other magnets it would stay intact without losing its magnetic quality. You can test this hypothesis by walking through a magnetised environment. You would be elated to observe that your Samco magnetic jewellery does not suffer any loss of magnetism.
There are few disadvantages of Samco magnet though. Due to its brittle nature it is prone to chipping on edges; however it does not fracture unless you hit with a hammer. Samco magnetic jewellery gives you positive cosmics in the form heightened awareness, increased metabolism and relief of pain in bones and joints. A major negative is that for some users it can increase toxicity. Those who suffer from eye and skin irritation are advised to wear it after consulting with a health professional.
