Round Magnets（Shape：Round）

Round magnets are products used to stick items to magnetic objects made of ferrous metals. Besides sticking objects together, they are also used for applications such as magnetism testing and in parts requiring magnetic attraction. Magnets are available in types such as neodymium, ferrite, cobalt and alnico. The magnetic force of neodymium magnets is one of the strongest among the available magnet products. Neodymium magnets are used in a wide range of applications. Ferrite magnets have a weak magnetic force but relatively high retentivity. Cobalt magnets are officially known as samarium-cobalt magnets. They are known for their resistance to rust and high temperatures. Alnico magnets have superior temperature resistance properties and outstanding mechanical strength. The high retentivity of industrial magnets enables even small models to emit powerful magnetic fields. Using a magnet at temperatures above its maximum operating temperature creates the risk of weakening its magnetic force.

Neodymium Magnet Bar Shape

Magna

This is a cylindrical (bar-shaped) magnet with excellent mechanical strength.

[Features]
· Rare-earth magnets are sorted into samarium-cobalt magnets and neodymium magnets.
· Samarium-cobalt magnets are known to be very powerful.
· Highly resistant to rust and high temperatures, but slightly lacking mechanical strength is slightly lacking.
· Neodymium is popular as a compact and lightweight material.
· Neodymium magnets create what is said to be the strongest magnetic field among magnets currently on the market.
· Can be machined into a round, square, or ring shape according to the application.
· With excellent mechanical strength, they are coated to prevent development of rust. Must be used at 80℃ or less.

Neodymium Magnet Round Shape

Magna

A round magnet with excellent mechanical strength.

[Features]
•Rare-earth magnets are divided into samarium-cobalt magnets and neodymium magnets.
•Samarium-cobalt magnets are known to be very powerful.
•Highly resistant to rust and high temperatures, but some issues with mechanical strength
•Like neodymium, popular as a compact and lightweight magnetic material
•Neodymium magnets are said to create the strongest magnetic field of any magnet currently on the market
•Can be machined into a round, square, or ring shape to suit the application
•Though it has excellent mechanical advantages, it must be coated to prevent rust development. Use at 80 °C or below.

Samarium-Cobalt Magnet Round Type

Magna

Ideal for medical devices and sensors thanks to good coercivity at temperatures as high as 350 ℃ and corrosion resistance. Mechanical strength can pose some issues, but product miniaturization and weight reduction can be achieved, as with neodymium magnets.

Volume Discount
Days to Ship: 9 Days or more
Alnico Magnet Bar Type

Magna

Excellent mechanical advantages such as being crack-proof and having high heat resistance. Though easily demagnetized, these magnets remain popular in metering and communications and are now finding new applications in security equipment and watt-hour meters.

Samarium-Cobalt Magnet Bar Shape

Magna

Resistance to demagnetization at temperatures as high as 350℃, as well as resistance to rust, make this a perfect component for medical devices and sensors. There are some difficulties in terms of mechanical strength, but miniaturization and weight reduction of the product can be achieved similar to neodymium products.

[Features]
· The unprecedented strength of the neodymium magnet with polyamide coating (powder coating) greatly improves the environment‐resistant characteristics compared with conventional plated products.
· Even after a 2, 000-hour salt spray test, durability is not compromised.
· Superior durability against cracks and chips thanks to the cutting-edge coating technology.
· Suitable for various applications because mold cases are not required and the design is highly flexible.
· Optimal for products that require direct contact with the skin, such as clothing, bags, toiletries, and kitchen and household products.
