Magnete ad arco nichelato

The Nickel Plated Arc Magnet (Ni-Cu-Ni) is the industry standard and the most popular surface treatment for sintered neodymium magnets. This classic triple-coating system—comprising a layer of Nickel, a layer of Copper, and a final layer of Nickel—provides an optimal balance of cost, durability, and performance. It delivers a bright, silver finish that is clean, smooth, and dimensionally consistent.

The Ni-Cu-Ni structure is renowned for its hardness and resistance to abrasion. It effectively seals the iron-rich magnet core from atmospheric humidity, preventing rust in standard indoor environments. The smooth surface has a low coefficient of friction, which aids in the assembly process, allowing the magnets to slide easily into motor slots or housings. It is the go-to solution for general-purpose motor applications where extreme environmental conditions are not a primary concern.
