Neodymium magnet with four-layer special anti-rust coating.
Rust-resistant neodymium magnets!! There are still no places that can handle them!!
Neodymium magnets are very prone to rust. Therefore, they are generally plated in three layers (nickel-copper-nickel). Our rust-resistant neodymium magnets have an additional layer, resulting in a four-layer plating (nickel-copper-nickel-electroless nickel). Please refer to the enlarged diagram below. You should be able to confirm the thickness of the plating. There are products that seem to accept that neodymium magnets will rust. Especially for items used outdoors, it may be said that they should be replaced once they rust. However, if an expensive product rusts quickly, consumers may not buy it again. In such cases, please use our neodymium magnets with a special four-layer plating. Features: ◎ With a four-layer structure that has a thick three-layer plating topped with pinhole-free plating, it is resistant to rust and can be used in water and outdoors. ◎ The intermediate layer of copper plating is thick and evenly applied, enhancing the shielding effect. ◎ Despite being metal-plated, it has a rust prevention effect lasting over 120 hours in salt spray tests (standard plating typically rusts after about 24 hours). ◎ We can accommodate small lot orders as well.
