Permanent magnets are utilized in various fields by applying attraction and repulsion forces, as well as electromagnetic induction and electromagnetic forces, and further demand is expected to rise in the future. In industrial products, they are used in motors, sensors, machine tools, measuring instruments, and are also incorporated into all kinds of consumer goods such as home appliances, audio equipment, communication devices, and automobiles. (For example, nearly 100 magnets are used per car.) Additionally, they are found in over 400 types of products ranging from precision instruments like MRI (Magnetic Resonance Imaging) machines and pacemakers to stationery and toys. 【Overview of Permanent Magnets】 ■ Ferrite Magnets 　⇒ Molded and sintered products primarily made of iron oxide ■ Neodymium Magnets 　⇒ Molded and sintered products primarily made of neodymium, iron, and boron ■ Samarium-Cobalt Magnets 　⇒ Molded and sintered products primarily made of samarium and cobalt ■ Alnico Magnets 　⇒ Cast products primarily made of iron, nickel, and cobalt ■ Rubber Magnets 　⇒ Molded products made by mixing magnetic powders such as ferrite or neodymium with resin ■ Cap Magnets 　⇒ Products that combine permanent magnets with a yoke (iron material) *For more details, please contact us at the information below or download the catalog.

Ferrite magnets are sintered products made using powder metallurgy. They are inexpensive magnets used when magnetic properties are stable and a strong magnetic field is not required. Generally, they are the dark-colored magnets you commonly see and are used in a wide range of applications. Please try the stock items first. If you order in bulk, there will be a lot discount, so please consider it.

• others

Neodymium magnets are sintered products primarily composed of neodymium, iron, and boron. They have an extremely high magnetic energy, the highest among existing magnets. Due to their susceptibility to rust, they are mainly surface-treated with nickel plating. We can also accommodate the production of small quantities of prototypes through machining. Please try our stock items first. If you order in bulk, there are lot discounts available, so please consider this.

• others

Samarium-cobalt magnets are sintered products primarily composed of samarium and cobalt. They possess excellent magnetic properties, second only to neodymium magnets. They are also resistant to high temperatures, but they are brittle, so care must be taken when handling them. Please start by trying the stock items. If you order in larger quantities, there are lot discounts available, so please consider that.

• others

Alnico magnets are made by casting. They are prone to demagnetization, but they have excellent properties with respect to temperature and are often used when stability of precision is required. Dimensions and shapes can be maintained with precision through polishing processes. Please start by trying out the stock items. If you order in larger quantities, there will be a lot discount, so please consider it.

Rubber magnets have excellent flexibility. They are easy to cut, process, and print, making them suitable for a wide range of applications. For small quantities, it is economical for customers to cut stock items themselves. For mass production, we can cut them to the desired size. There are also color sheets and options with adhesive on one side. Please try starting with stock items. If you order in bulk, there are lot discounts available, so please consider this. *The magnetic strength relationships for the same size are as follows: Isotropic ferrite < Anisotropic ferrite < Neodymium We can also accommodate top and bottom NS magnetization, printing, adhesive tape, PP lamination, etc. Round, ring, and special shapes can be produced in small quantities without the need for a die.

Cap magnets are products that effectively utilize magnetic energy. They only attract to the magnetic surface, but they provide a strong adhesive force. Additionally, since the area outside the adhesive surface is made of yoke (iron material), they have excellent impact resistance. Please try the stock items first. If you order in bulk, there is a lot discount available, so please consider it. Magnetic field lines concentrate between the magnetic surface and the surrounding iron. As a result, the adhesive force becomes 3 to 4 times stronger than that of the magnet alone. However, since the magnetic field lines do not extend far, care must be taken to avoid leaving gaps between the magnet and the object being attracted. We can also provide protective films and double-sided tape. Yokes (iron materials) and various magnets can be manufactured to your desired size.

It is suitable for neodymium magnets and yokes (iron materials) that are prone to rust due to their high hardness and excellent corrosion resistance. We can also accommodate single-layer nickel plating and three-layer plating of nickel, copper, and nickel. Electrolytic nickel plating is common, but we can also produce it with electroless nickel plating, achieving a uniform film thickness.

• others

It has high hardness and excellent corrosion resistance and adhesion. It is also used for surface treatment of general industrial products (such as bolts, nuts, and washers). Neodymium magnets are very prone to rust, so nickel plating may be applied as a base layer.

• others

It has excellent electrical conductivity, corrosion resistance, and wear resistance. Additionally, due to its excellent light reflectivity, it is widely used as a decorative surface treatment. Neodymium magnets are often coated with nickel plating as a base. Note that gold plating is different from gold-colored plating.

• others

It is highly resistant to corrosion, making it suitable for easily rusting neodymium magnets. Additionally, it has high impact resistance, making it suitable for easily cracking ferrite magnets. It can be treated in various colors and is used for a wide range of applications.

• others

It has excellent heat resistance, corrosion resistance, chemical resistance, abrasion resistance, and insulation properties. Additionally, it has a high non-stick property that prevents most substances from adhering. It is commonly referred to as Teflon coating. Neodymium magnets are often nickel-plated as a base. Our company offers two types of fluoropolymer coatings (PTFE and PFA).

• others

It is suitable for rust-prone neodymium magnets and yokes (iron materials) due to its excellent corrosion resistance. Additionally, because of its high adhesion, delamination due to impact or friction is less likely to occur. Primarily, chromate treatment is performed to enhance corrosion resistance. Previously, hexavalent chromium was included, but it has now been replaced with trivalent chromium.
