Alnico Permanent Magnetism is a permanent magnet which is made from an alloy of aluminum, nickel and cobalt and is one of the strongest permanent magnets available. Alnico 5 and Alnico 8 are the two grades of Alnico magnets normally used. They have excellent temperature stability and can be used in applications where temperatures exceed 550℃. Alnico magnets are strong and have good temperature stability. Alnico magnets have a high coercive force and good temperature stability. The tolerance of Alnico magnets is ±0.05mm and the Hcj value is ≥30 KA/m. Alnico magnets are widely used in various applications due to their high performance and reliability.

UNMAG Alnico Permanent Magnet is a kind of magnet made of alloy material with a combination of aluminum, nickel and cobalt. It is widely used in many applications and provides exceptional magnetic properties such as high magnetic flux density, strong coercivity, and excellent temperature stability. It is also resistant to corrosion and demagnetization. UNMAG Alnico Permanent Magnet is well-known for its powerful magnetic field and high magnetic flux density, which can reach up to 1.13-9MGOe. Its magnetization direction can be axial, radial, multi-poles and so on, and its tolerance level is ±0.05mm. In addition, its Hcj can reach up to 30KA/m, which makes it ideal for generator, microphone, measuring instrument and other applications. All UNMAG Alnico Permanent Magnet products are made in China with a delivery time of 25-30days.
UNMAG is proud to offer premium quality Alnico Permanent Magnetism, made with Cast Alnico from China with delivery times of 25-30 days. Our Alnico Permanent Magnetism features a tolerances of ±0.05mm and come in a variety of Permanent Magnet types including Axial, Radial, and Multi-poles, with a BHmax of 1.13-9 MGOe.
Alnico Permanent Magnet Packaging and Shipping
Alnico Permanent Magnets should be packaged in a sturdy container with cushioning material to protect and prevent them from being damaged. The container should be properly sealed to ensure that no magnets are lost during transport.
Shipping should be done through a reliable courier service, as magnets are prone to being attracted to each other and can cause damage if they are not properly separated. The magnet should also be labeled properly to avoid any confusion.
