The strong neodymium(NdFeB) cone magnets are special disc or cylinder magnets that the two ends have not the same size. One rare earth strong neodymium cone magnet is expressed by bottom diameter(D1)x top diameter(D2) x thickness(T).
Rare earth neodymium cone magnets: precision-engineered for versatile applications, these custom magnets redefine performance, providing unmatched reliability and efficiency in diverse industrial and creative settings.
Surface treatment for rare earth neodymium cone magnets is essential for optimal performance. Common treatments, such as coating with materials like nickel or zinc, enhance resistance to corrosion, wear, and environmental factors, ensuring prolonged effectiveness in various applications.
