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.

NEOMAG

[Features]
· Neodymium magnets are the strongest magnets of all, and are ideal for reducing size and increasing the performance of devices.
· However, on its own, the material is weak to rust and so has been finished with a nickel plating. Thanks to the excellent rustproofing and durability properties of the plating technology, it should encounter no problems under normal usage conditions.
· Used widely in various cutting-edge fields such as in cell phones, HDDs, hybrid cars, etc.
