12 years professional magnet manufacturer to you explain what's the difference between the rare earths and ferrite
Now find commercialization of the highest performance magnets, known as magnetic king, has the extremely high magnetic to its maximum magnetic energy product (
Up to 10 times higher than ferrite.
Magnet manufacturer to introduce the difference between the rare earths and ferrite itself of machining performance is also quite good.
Working temperature up to 200 degrees Celsius.
And the quality of a material is solid, stable performance, good cost performance, so its application is very extensive.
But because of its chemical activity is very strong, so you have to handle with polish on the surface layer.
Such as zinc plating, Ni, electrophoresis, passivation, etc. )
According to the composition of different divided into SmCo5 and Sm2Co17.
Because its material is expensive and make its development was restricted.
Samarium cobalt (
As a rare earth permanent magnets, not only have higher magnetic energy product (
And reliable coercive force and good temperature characteristic.
Compared with the ndfeb magnets, samarium cobalt magnet is more suitable for working in high temperature environment.
Its main raw materials including BaFe12O19 and SrFe12O19.
Manufactured by ceramic technology, the quality of a material is hard, brittle material, because the magnet ferrite magnet manufacturer have good temperature resistance, low cost, moderate performance, has become the most widely applied permanent magnets.
Is made from aluminum, nickel, cobalt, iron and other trace metal elements of an alloy.
Casting process can be processed into different sizes and shapes, machinability is good.
Casting aluminum nickel and cobalt permanent magnet has the lowest temperature coefficient is reversible, working temperature can be as high as 600 degrees Celsius above.
Magnet factory products are widely used in all kinds of instruments and meters and other application fields.
