Neodymium Magnets Big Ring Sintered NdFeB Supermagneti Magnete Permanente
Ring magneti permanenti has three dimensions: outer diameter, inner diameter and thickness (height), so the dimension of Ring magneti permanenti is measured as "Outer Diameter" X Inner Diameter" X "Thickness (Height)".

Neodymium Magnets Big Ring Sintered NdFeB Supermagneti Magnete Permanente


Direction of Magnetization: Axially Magnetized (Magnetized through 17mm thickness).

Neodymium Magnets Big Ring Sintered NdFeB Supermagneti Magnete Permanente
Magnetic Pull Force: About 85kgs (187.7lbs)
Surface Field (on axis): About 4,982 Gauss

Alnico (Aluminum Nickel Cobalt) magnet alloy exhibits excellent temperature stability and a high Residual Induction (Br). Alnico magnets are largely comprised of Iron, Cobalt, Aluminum, and Nickel with trace amounts of other elements used to tailor the alloy's magnetic and mechanical properties. Alnico magnet alloy is a mature technology and is manufactured by casting or sintering. The Alnico magnet manufacturing process and the method used to develop anisotropy allow for geometries that are more complex compared to other magnet alloys.

Alnico magnets have a low Coercive Force (Hc) which results in this alloy being easily demagnetized. Commercially viable magnet designs with Alnico require a long magnetic length relative the magnet's pole cross-section. To counteract this necessity, Alnico magnets are usually used in conjunction with high permeability materials which act as a yoke or return path. There are grades of Alnico magnets which have higher Coercive Forces, and therefore, exhibit higher degrees of resistance to demagnetization, but the cost increases and the mechanical characteristics degrade with these grades. Alnico magnets also have a low Energy Product (BHmax) when compared to the Rare Earth magnet alloys, even though their Residual Inductions (Br) are comparable. In many applications Alnico is now being replaced with much smaller Rare Earth magnets.
