Folding NdFeB magnets - still excellent magnetic

ndfeb magnets can be divided into two kinds of sintered NdFeB and Bonded NdFeB. Injection molding is actually bonded, and sintering is heated to high temperatures by vacuum molding! Various shapes according to specific requirements of processing:, round, square, drilling, magnetic tile, magnetic, convex, trapezoidal; despite these advantages, but the surface is easy to rust, so usually require some protective surface treatment: nickel, zinc,, gold-plated, and epoxy resins. sintered ndfeb magnets applicable environmental temperature is below 200 degrees, mainly used in electronics, electrical appliances, packaging, electrical, toys, leather goods, auto mechanics, etc.

Production Process

Process: Ingredients → smelting ingot / dump-pressure belt → milling → → → sintering temper magnetic detection → grinding → pin Qiejia → plating → finished. Which is the basis of the ingredients, tempering sintering is the key. neodymium ring magnet rough production tools and performance testing tools: There melting furnace, thrown with furnace, jaw broken machine, jet mill, pressing machines, vacuum packaging machines, isostatic presses, sintering furnace, vacuum heat treatment furnace, magnetic test meter, Gauss Meter. ndfeb magnets machining tool: centerless grinding, rounded machine, double-side grinding, grinding, slicing machines, double-sided grinding, cutting lines, Tianjin Expressway, Lake bench drill, contour grinding

characteristic

neodymium block magnets are currently found in the commercialization of the highest performance magnets, known as magnetic king, we have extremely high magnetic its biggest energy product higher than the ferrite  more than 10 times. Machining performance itself is also very good. Operating temperature up to 200 degrees Celsius. And its hard texture, stable performance, good price, so its application is extremely broad. But because of its chemical activity is very strong, neodymium iron boron it must deal with its surface coating

Latest research

High iron concentration samarium cobalt heatable magnetic filter newly developed independently developed using Toshiba's heat treatment technology, so that the original magnetic force neodymium magnet is inferior to samarium cobalt magnet has a heat-resistant block neodymium magnets beyond the strong magnetic environment at 100 degrees Celsius. In order to increase the magnetic force, R & D staff will iron weight ratio increased from the original 15% to 20-25%, and adjusted when the sintering temperature, time and pressure to achieve the best state, thereby reducing the obstruction increases magnetic oxide substrates and other factors. In the 2012 annual plan of this new magnet weekend market

Performance samarium cobalt magnets

super neodymium magnets can easily peel broken. When dealing with them must wear goggles.
Let magnet magnet smash hit together may lead, which can cause potentially dangerous.
Samarium cobalt produced by a sintering process is called, and all made of sintered material, inside is very likely to crack. Does not have the mechanical integrity of the magnet, the hump magnets only has the function of preparing. Therefore, the mechanical system must be designed in particular to give sufficient mechanical reliability of the overall system

the magnetic circles known as Magneto

ndfeb magnets is the third generation of rare earth permanent magnet materials, small size, light weight and strong magnetic features, is currently the best price-performance magnet, the magnetic circles known as Magneto. The advantages of high energy density make NdFeB been widely used in modern industrial and electronic technology. In the state of bare neodymium block magnet, 3,500 gauss magnetic force can achieve

Ferrite magnet is a ferromagnetic metal oxide

Ferrite magnet is a ferromagnetic metal oxide. On the electrical characteristics, the ferrite resistivity than metal, alloy magnetic material is much greater, but also a higher dielectric properties. The samarium magnets ferrite having a high performance can be further permeability at high frequencies. Thus, a wide range of high-frequency ferrite has become weak areas of use of non-metallic material. Belongs to non-metallic magnetic material is iron oxide and one or more metal oxides other composite oxide magnetic tubes
