Ferrite magnets china are permanent magnets made mainly from SrO or BaO and Fe2O3-- They are electrically insulating so current does not pass through them due to their extremely high electrical resistance, hence their other name of Ceramic Magnets. Compared with other permanent magnets, ferrite magnets are hard and brittle, with lower magnetic energy. However, it is not easy to demagnetize and corrode, and the production process is simple and inexpensive. Therefore, ferrite magnets have the highest production volume in the whole magnet industry and are widely used in other industries. What Are The Differences Between Hard Magnets and Soft Magnets of Ferrite Magnets Hard Magnets The ferrite used in permanent magnets is hard ferrite, which has high coactivity and reminisces after magnetization. Iron oxide and barium carbonate or strontium carbonate are used to make hard ferrite. Because of their high coactivity, hard ferrites are not easily demagnetized, which is an important characteristic of permanent magnets. Hard ferrites can produce magnetic flux and also have a high magnetic permeability. Hard ferrites, also known as ceramic magnets, are inexpensive and are commonly used in household products (e.g. refrigerator magnets). Soft Magnets Ferrites used in transformers or electromagnet cores that include nickel; zinc or manganese compounds have a low coactivity and are generally referred to as soft ferrites. The low coactivity means that the magnetization strength of the material can be changed from positive to negative without consuming much energy (hysteresis), and the high resistivity of the material itself reduces another source of energy loss: the generation of eddy currents. Due to the low losses at high frequencies, it is commonly used in the cores of RF transformers and in the reactors used in switching power supplies. FAQs About Ferrite Magnets  What are ferrite magnets used for? Hard ferrites are used to make permanent magnets such as refrigerator magnets, speakers and small electric motors. Soft ferrites have low interactivity, so they easily change magnetization, acting as conductors of magnetic fields. Are ferrite magnets safe? Magnets are incredibly useful and fun, but they also have danger. Ferrite magnets can shatter into pieces if you apply force repeatedly. Fragments of the broken magnet may cause injury to the user or stand. How do you cut a ferrite magnet? Ferrite cannot be cut with ordinary tools. However, it is possible to use the heating ring cutting method. Specifically, a resistance wire is used to form a ring at the prepared cutting point to form a large temperature difference through a large current and then quickly cooled.

Strongest double sided fishing magnet is specifically designed for magnet fishing. You don't have to worry about the orientation of the magnet in the water as each side provides at least 70KG of pulling power. Is a double sided neodymium fishing magnet Better for Magnet Fishing? The new design provides more versatility by allowing it to be used as a double sided, or single side magnet. The eyebolt can screw into the side of the casing, or through the magnet face. Using double sided fishing magnet in the single sided configuration will provide a stronger hold since the user is pulling perpendicular to the target. Structures of double sided fishing magnets for sale Have another eyelet. Made of steel plate. Coated with Ni-Cu-Ni. NdFeB is the strongest and most durable permanent magnet available. If you need any kinds of magnetic products, please contact us, as a professional Magnetic assembly supplier, Souwest magnetech is willing to offer you high quality products.

A deep pot magnet is a type of pot magnet. The magnet is housed in a cylindrical housing, usually made of galvanized steel or copper-zinc alloy and brass. The deep pot magnets can be glued in, pressed in, or shrunk in. Types of Deep Pot Magnets Deep Pot Magnets SWN0 Deep Pot Magnets SWA1 Deep Pot Magnets SWA3 Deep Pot Magnets SWNP The magnetic core of the deep pot magnets The cores of deep pot magnets are made of neodymium (NdFeB), samarium cobalt (SmCo) or aluminum-nickel-cobalt (Alnico) alloys. Depending on the material used, deep basin magnets have different bonding forces and respond differently to high-temperature requirements. ● Although, Alnico magnets have a good suction force, NdFeB magnets have the strongest suction force. SmCo falls between the other two magnet systems. ● With regard to temperature resistance, the opposite is true. Alnico magnets tolerate the most heat and NdFeB magnets are the least heat resistant. Magnets reach the following maximum operating temperatures: NdFeB 80°C / SmCo 250°C / Alnico 450°C. What do you have to pay attention to when installing deep pot magnets? When installing a deep pot magnet -- it does not matter whether the housing is galvanized or made of brass, but it is important to ensure that it is not directly surrounded by iron. Iron reduces the suction power by 15%. So a gap of a few millimeters between the casing and the surrounding iron needs to be left to solve this problem. The pole side of the deep pot magnets should always be kept clean, which ensures maximum effectiveness when you apply or separate it from the surface. The holding power of the magnets will also be reduced if it is used on an uneven, painted surface. Souwest Magnetech is a professional deep pot magnets factory, we provide magnets material, cylinder magnet ndfeb, rare earth cylinder magnets, heavy duty magnetic hooks, etc. For more information, please feel free to contact us!

Strong NdFeB cylinder magnets, also called Round Neodymium Magnet, like our other super magnets, are made of a special NdFeB alloy, which allows Cylinder Neodymium Magnet to achieve an extreme adhesive force of up to 200 kg. Their high magnetic strength, resistance to demagnetization, low cost and versatility make them your ideal choice for applications. Advantages About Cylinder Neodymium Magnet ◆ Custom-made ◆ Good value for money ◆ High magnetic properties can reach N55 -- the most strong magnets at room temperature ◆ Maximum outer diameter(OD) can reach 150mm and special grade N35 can reach 200mm OD ◆ Axial magnetization will be cheaper than the radial magnetization ◆ Variety of surface treatments: Protective nickel coating, some with additional gold or copper plating, or epoxy resin coating Tips of cylinder magnets for sale Shipping Sea freight is recommended. As air freight requires magnetic shielding, it will increase the weight cost. Note Dangerous Adhesive force is strong, pay attention to the danger of clamping hands. Souwest Magnetech is a professional magnetic assembly factory, we provide diametrically magnetized cylinder neodymium magnet, cylinder magnet ndfeb, rare earth cylinder magnets, countersunk magnets, etc. For more information, please feel free to contact us!

Aluminium is also very light and strong. With its excellent strength-to-weight ratio, it is essential for the automotive and aerospace industries. Other advantages are that it is non-magnetic, non-combustible, increases in strength as the temperature decreases, non-toxic and an efficient conductor of heat/electricity. Aluminium is commonly used in solar technology and similar applications and can reflect light and heat. Stamped aluminium products are also used in the aerospace, industrial, marine, medical, construction, automotive, lighting and electronics industries. Aluminium can be recycled without deterioration and is therefore highly sustainable. It is corrosion resistant as it produces a natural oxide coating and is resistant to moisture and most chemicals.
