We provide extremely powerful permanent magnets of the highest quality made of neodymium rare earth alloy (Nd2Fe14B).
Neodymium is the world’s strongest magnetic material. Each magnet is nickel (Ni) plated for protection.
The nickel coating is durable, but neodymium magnets are brittle and can chip or shatter. Avoid smashing them together from some distance. If used gently, these magnets can serve you for a lifetime. These do NOT lose magnetic pull force due to time.
