I need them charged and glued to plates that we will supply. Material: Neodymium Permanent MagnetShape: Arc NdFeB Magnetic Assembly Manufacturer China Rare Earth Magnet Limited:Regarding your enquiry of the magnets, what will be the magnetization orientation of the arc magnets?Across diameter, 50% N-S and 50% S-N?Inquire Neodymium Arc Magnets with Halbach Arrays:These are Halbach arrays. So, if you numbered the magnets like a clock around the arc, every other magnet would be magnetized through the thickness.#1 would be N-S#3 would be S-N#5 would be N-S#7 would be S-N …and on and on that way.For the even numbered magnets between the magnets above, they are magnetized 90 degrees to the odd ones above, so that magnetic flux runs along the arc and not through it.#2 would be N-S through the arc#4 would be S-N through the arc#6 would be N-S through the arc#8 would be S-N though the arcWhen #1-#8 get assembled, they form a halbach array. These neodymium magnets are symmetrical. So, for manufacturing purposes, I think it is simple.HALF of the magnets are magnetized through the thickness, and HALF of the magnets are magnetized through the arc length. The orientation of the N-S poles will be organized when the magnets are glued to the back iron. Is this clear?We would like a price for the magnetized magnets, with N and S marked. We would also like a price for the magnets glued to back iron (we will supply the back iron).

Magnetoconductivity of Stainless Steel 20160614

Why stainless steel cannot be attracted by permanent magnet?In daily life, austenitic (also known as Ni steel) and martensitic referred to steel, but such name is not scientific, easy misunderstand should avoided) are the two types of which people most familiar with. The reason why attractable … Why stainless steel cannot be attracted by permanent magnet?In daily life, austenitic stainless steel (also known as Ni stainless steel) and martensitic stainless steel (also referred to as stainless steel, but such name is not scientific, easy to misunderstand and should be avoided) are the two types of stainless steel which people are most familiar with. The reason why austenitic stainless steel is not attractable to magnets is that there is high percentage of Ni and Cr in it(Cr about 18% and Ni ≥4%), which makes the internal structure of it presents a so called austenite microstructure. The austenite structure is non-magnetic, so austenitic stainless steel cannot be attracted to any strong permanent magnets like neodymium magnets , ferrite magnets. The austenitic microstructure of steel will lose its ferromagnetism at temperature above 770 degrees Celsius. Austenitic stainless steel with large proportion of alloy is also not ferromagnetic. Except for the austenitic steel, other types of stainless steel are ferromagnetic such as ferritic stainless steel, martensitic stainless steel and so on. Stainless steels that can be attracted by strong magnets are called Cr13, and stainless iron 1Cr18Ni9Ti and 0Cr18Ni9Ti, etc..People often test the quality and genuineness of stainless steel using a neodymium permanent magnet . If the stainless steel is not attractive to magnets, it is thought to be qualified. Actually, such test method is not realistic. Anyone who has rich experience in producing steel material will never apply this confusing test method to verify stainless steel.According to manufacturers of stainless steels, there is a variety of stainless steel, which can be categorized into austenitic stainless steel and martensitic stainless steel based on their structure at room temperature. Austenitic steel is no magnetic or weakly magnetic, while martensite or ferrite steel is magnetic. However, it is not necessarily the case. For an example of austenitic 304 stainless steels that are commonly used as tube plates in decoration, they are nonmagnetic, but they might appear magnetic due to fluctuations of chemical composition in melting or different processing status. So such magnetism of stainless steel is not a proof of inferior quality. Beside, the inner structure of 304stainless steel may transform to be martensitic after cold processing. The greater the degree of cold processing, the more the martensitic transformation is, and the stronger the magnetism of the steel will be. On the contrary, the 200 series stainless steel with inferior quality might probably be non-magnetic. Therefore, verifying the quality and genuineness of stainless steel by testing its magnetism is terribly wrong. View Details

Each carton may be 18-19kgs.May I know how you will ship the permanent magnets, by air or by express? In addition, please make sure that your forwarder is able to ship magnets, because there are many restrictions in shipping magnets in China.Most of the shipping companies reject shipping magnets, because they think magnets are dangerous objects.Previously, some of our customers arranged the shipment by themselves. However, their agents in China refused and returned the magnets to us.Then we have to arrange the shipment by our own finally, which waste much time and money. Above are our concerns of the shipment of your magnets. View Details

But not … Custom AlNiCo Rare Earth Permanent Magnets Sintered alnico magnets produced by powder metallurgy technology. According to comprehensive introduction to alnico in Wikipedia, material composition of alnico permanent magnet includes aluminum, nickel, cobalt, aluminum, nickel, cobalt, copper, titanium, iron, and niobium. But not every grade of alnico rare earth magnet includes all of the aforementioned materials. For example, grade Alnico 1 is usually referred to as aluminum-nickel alloy, which means it does not contain cobalt, and grades below alnico 5 do not contain titanium. Generally, alnico magnets are iron based alloy with iron taking the largest proportion of raw material, aluminum taking less than 8%, and cobalt 38% or less. Technological properties of sintered Alnico magnets: metal powder mixture is molded into blank with different sizes by press mold; the raw material blank will be sintered in vacuum or gas protection furnace; the alloyed blank will have heat treatment, thus magnetism is achieved. Magnets produced by the above technologic process are characterized by their simple shapes, which is mainly because the powder press molding is not suitable for complex shapes manufacturing. In addition, high dimensional precision is a main characteristic of powder press molding. Different from wire cutting technique for neodymium magnet , sintered alnico magnets are usually produced by single shot shaping technique which makes alnico magnets very suitable to be applied in high precision magnetic parts. The magnetic strength of sintered alnico magnets is slightly weaker than that of cast alnico permanent magnets. The strongest trait of alnico magnets is the consistency of magnetic performance. Alnico rare earth magnets are excellent high temperature resistant magnetic material with temperature coefficient -0.01%/C~-0.02%/C. Thus, they are most widely used in electric meters, motors, magnetic sensors, instruments, relays and other high temperature, high precision magnetic parts. View Details
