Shenzhen ndfeb manufacturers solve size of permanent magnet magnetic ordering
Shenzhen manufacturer ndfeb magnet magnetic size is: ndfeb magnets, samarium cobalt magnet, alnico magnets, ferrite magnets.
On top of, of course, is one of the characteristics of ndfeb magnet ndfeb magnets, ndfeb permanent magnet material is based on intermetallic compounds Nd2Fe14B permanent magnet materials.
High magnetic energy product and JiaoLi, at the same time, the advantages of high energy density makes the summary in the modern industry and the wide application of electronic technology, so that the instruments and meters, electronic motor, magnetization of the magnetic separation equipment miniaturization, lightweight, thin become possible.
Material characteristics: the advantage of ndfeb is cost-effective, good mechanical properties;
Lack of Curie temperature in low point, temperature characteristic is poor, and is easy to be pulverization corrosion, must through the adjust its chemical composition and take surface treatment methods to improve, to reach the requirements of practical application.
Manufacturing process: the summary of manufacturing powder metallurgy process.
Shenzhen ndfeb manufacturers process: ingredients to smelting tableting, pulverizing to molding, sintering and tempering magnetic detection to grinding to pin cutting processing, electroplating, finished product.
Ferrite magnet ferrite magnet characteristic: it is the main raw material includes BaFe12O19 and SrFe12O19.
Manufactured by ceramic technology, the quality of a material is hard, brittle material, because of the ferrite magnets have good temperature resistance, low cost, moderate performance, has become the most widely applied permanent magnets.
Magnetic ferrite magnet properties: high, good time stability and low temperature coefficient.
Application places: ferrite magnet is widely used in electric meter, instrument, electrical, automatic control, microwave device, radar and medical equipment, etc.
Ferrite magnet magnetization direction: axial and radial or magnetization as required.
Can produce cylindrical, ferrite magnet shapes: circular, rectangular in shape, the sector, tile shape, axe.
Alnico magnet alnico magnet features: is made from aluminum, nickel, cobalt, iron and other trace metal elements constitute a kind of 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.
Alnico permanent magnet products are widely used in all kinds of instruments and meters and other application fields.
Alnico magnet classification: can be divided into casting aluminum nickel and cobalt and sintered alnico two kinds big.
Aluminum nickel and cobalt application places: casting aluminum nickel and cobalt products are mainly applied in auto parts, instruments and meters, electronic, electrical, teaching, and aerospace fields such as military, has low temperature coefficient, high temperature resistant, resistant to moisture, it is not easy oxidation and the working stability is good wait for an advantage.
Sintered alnico adopt the method of powder metallurgy production and become, is suitable for the production of complex shape, light, thin, small products, widely used in instruments and meters, communication, magnetoelectric switch and all kinds of sensors.
Can produce cylindrical, alnico magnet shape: circular, rectangular in shape, flat type, form, horseshoe.
Samarium cobalt magnet, samarium cobalt magnet is also called the samarium cobalt magnet steel, samarium cobalt permanent magnet, samarium cobalt permanent magnet, samarium cobalt magnet, rare earth cobalt permanent magnet, etc.
Consists of samarium, cobalt and other rare earth metal material proportioning, smelting alloy, after grinding, molding, sintering, made of a magnetic material, high magnetic energy product, low temperature coefficient, the highest working temperature is 350 ℃, no negative temperature, in operating temperature above 180 ℃, the maximum magnetic energy product and temperature stability and chemical stability than ndfeb permanent magnet materials.
Have strong corrosion resistance and oxidation resistance;
So is widely used in aerospace, national defense, microwave devices, communication, medical equipment, instruments, meters, all kinds of magnetic actuator, sensor, magnetic, electrical, magnetic crane processor, etc.
Shenzhen ndfeb manufacturers production process: the ingredients - melting tableting - milling to molding, sintering tempering to magnetic detection, grinding to pin cutting processing, the finished product samarium cobalt magnet shape: typical garden piece of article, circle, square, square, tile shape, special shape according to processing.
