Alnico Magnets Cylindrical Rod

Alnico magnets, known for their bright red color, are made of aluminum, nickel, cobalt, and other metals. They are also known for their high magnetic properties and stability at high temperatures. Unlike rare earth magnets, Alnico Magnets are not as brittle and have a greater resistance to demagnetization; this makes them ideal for use in various industries, including aerospace, electronics, and instrumentation. They are also popular for other applications such as educational experiments, arts and crafts, and magnetic therapy.    From holding objects in place to generating electricity, Alnico Magnets are versatile and powerful tools. FIRST4MAGNETS carry various shapes and sizes, such as alnico cylinder magnets, alnico block magnets, threaded magnets, and alnico horseshoe magnets, each with their own unique properties and use. With a strong focus on quality and customer satisfaction, FIRST4MAGNETS is your go-to source for all your magnet needs.

Introduced in the 1930s, Alnico magnets were the first permanent magnets to be mass produced and very quickly surpassed steel-based ‘soft’ magnets due to their vastly superior performance. The composite elements of Alnico magnets are aluminium (Al), nickel (Ni) and cobalt (Co), hence where the term Alnico comes from, however they contain other elements including but not limited to iron, copper and titanium.

Alnico magnets have the widest spectrum of strengths of any permanent magnetic material. It is possible that the Alnico grades with the best magnetic performance in the right application can match the performance of neodymium magnets.

Cast Alnico magnets have better magnetic properties and produce stronger magnetic fields than sintered Alnico magnet, however sintered Alnico magnets have greater mechanical strength and provide a more uniform magnetic field.  We can also supply isotropic Alnico magnets, which can be re-magnetised in any direction. While isotropic magnets are weaker in magnetic performance, and therefore are less commonly used, they offer more flexibility in terms of design.
