Samakoba magnet
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 will be a lot discount, so please consider it.
It's broken!
There is a possibility that it may break due to impacts such as suction or dropping. In particular, neodymium magnets and samarium-cobalt magnets have strong magnetic forces, and if they are attracted with too much force, there is a high risk of damage, so care must be taken when handling them. Please be careful not to attract nearby magnetic materials immediately after removal. Additionally, magnets with countersunk holes that can be fixed with countersunk screws or bolts may break if tightened too much. Please consider the optimal tightening torque that will not damage the magnet.
Utilized in various fields such as MRI, pacemakers, electronic devices, audio equipment, communication devices, and automobiles! Immediate shipping available from just one magnet, with no need to hold inventory!
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 increase 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 electrical appliances, audio equipment, communication devices, and automobiles. (For example, nearly 100 magnets are used per automobile.) 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 ⇒ Shaped sintered products mainly composed of iron oxide ■ Neodymium Magnets ⇒ Shaped sintered products mainly composed of neodymium, iron, and boron ■ Samarium-Cobalt Magnets ⇒ Shaped sintered products mainly composed of samarium and cobalt ■ Alnico Magnets ⇒ Cast products mainly composed of iron, nickel, and cobalt ■ Rubber Magnets ⇒ Molded products made by mixing magnetic powders like 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 address below or download the catalog.
Understand the basics of magnets! We are giving away a comprehensive catalog of permanent magnets featuring characteristics and product examples, along with the latest inventory list.
This is the "Permanent Magnet Products Comprehensive Catalog" from Niroku Seisakusho, which processes and sells permanent magnets and related products. It includes numerous listings of the characteristics and examples of each type of magnet. 【Featured Products (Partial)】 ◆ Ferrite Magnets These offer the best cost performance. They are brittle but resistant to rust. ◆ Neodymium Magnets These have the highest magnetic energy among existing magnets. They are prone to rust, so they are treated with nickel plating for rust prevention. ◆ Samarium Cobalt Magnets These have high magnetic energy, second only to neodymium magnets. They are brittle but can be used in high-temperature environments. ◆ Other related products/magnetic application devices, etc. For products in stock, orders placed by 5 PM can be shipped the same day with free shipping across Japan for as little as one magnet. Please consult us for custom magnets, including short lead times for basic shapes and production of special shapes. 【Stock List of Featured Products】 We have a wide range of ferrite magnets, neodymium magnets, samarium cobalt magnets, alnico magnets, rubber magnets, cap magnets, and related products listed by various shapes and sizes. For more details, please check with us.

Shipping nationwide on the same day from just one piece. Neodymium magnets are permanent magnets with the strongest magnetic force, allowing for miniaturization and thinness.
Shipping nationwide on the same day from just one piece. Neodymium magnets are the strongest permanent magnets, allowing for miniaturization and thin designs. They are over eight times stronger than anisotropic ferrite magnets. In terms of shape, there are types with screwable countersunk holes. Discounts for bulk purchases are available, and we can discuss pricing. Neodymium magnets can be custom-made in small quantities. As for the applications of neodymium magnets, quantitatively, they are mostly used in various motors, MRI machines, and disk drives for magnetic recording devices. However, they are also used in a wide range of situations, including for displays, golf markers, magnetic fixtures, jigs, transportation, and experiments.
Easy-to-use magnet! Twist to turn ON/OFF.
Ideal for loading and unloading workpieces for machine tools! ● Easy on/off switching with just a 45° twist ● Long lifespan achieved with a magnet shaft equipped with ball bearings and a corrosion-resistant surface ● Optional handles sold separately, with choices for hold grips and extended long handles *For more details, please feel free to contact us.
Supplies high-quality electricity through a continuous combustion method using direct turbine rotation.
It is anticipated that sudden power outages due to natural disasters such as earthquakes, thunderstorms, and typhoons, as well as fires and equipment failures, may render fire protection systems, communication systems, and evacuation facilities in buildings, hospitals, factories, department stores, hotels, and underground shopping areas inoperable. The Fire Service Act mandates the installation of self-generating power systems that comply with fire safety regulations, along with fire protection equipment such as small rivers, sprinklers, and pneumonia equipment. These power generation systems are essential for protecting vital lifelines.

It is a magnet with excellent temperature characteristics, strong magnetic force, and resistance to rust.
This is a rare earth magnet composed of samarium and cobalt. It has excellent temperature characteristics and stability even in high-temperature working environments. In working environments ranging from 250°C to 350°C, the maximum energy value reaches 29-32 MGOe. It also has high corrosion resistance, so surface treatments such as plating are unnecessary. 【Features】 ● It is ideal for applications requiring temperature stability and high-temperature conditions (250-350°C) due to its excellent temperature characteristics. ● It is more resistant to thermal demagnetization compared to neodymium magnets, demonstrating its superiority in high-temperature working environments. ● It is resistant to rust, so surface treatments such as plating are generally unnecessary. ● There are Sm2Co5 and Sm2Co17 systems with different composition ratios; the latter has better heat resistance and magnetic strength and can be adapted for machining. The former is relatively unsuitable for special shapes. ● It is widely used in precision instruments for special applications, aerospace and military parts, as well as medical devices like MRI machines, radar equipment, high-precision electronics, and stirrers.
