サンギョウサプライ Product Lineup

When it comes to powerful magnets, you may be familiar with neodymium magnets, but neodymium cap magnets are powerful magnets that enhance the adhesion strength of neodymium magnets several times over. They are several times stronger than ferrite cap magnets, but the original adhesion strength can be fully realized when the thickness of the steel surface on the opposing side is greater. Conversely, if the thickness of the steel plate is thin, the magnetic force of the neodymium cap magnet may overflow from the iron plate, resulting in insufficient adhesion strength. 【Features of Neodymium Cap Magnets】 - When combined with a cap (made of iron), they have several times the adhesion strength of a standalone neodymium magnet. - The magnetic force is concentrated at the tip of the cap, so the back side is not an adhesion surface. 【Common Uses of Neodymium Cap Magnets】 - For fixing products - For lifting dropped items - Used by directly adhering to the adhesion surface without leaving a gap between them. - Use stainless steel screws that do not attract the magnet for installation. Cautions - Since they are strong magnets with high adhesion strength, they cannot be easily removed once adhered. - It is very dangerous if you are not accustomed to handling magnets, so please use them only if you are experienced. Additionally, please read the instruction manual carefully before use and prioritize safety during operation.

Shipping nationwide from just one piece, with same-day shipping on weekdays. Free shipping for orders over 3,000 yen in total with other items. The magnetic force is the strongest, and it can be miniaturized and made thinner. Neodymium magnets are over eight times stronger than anisotropic ferrite magnets, and there are types available with screw holes for mounting. Standard neodymium magnets are in stock in various sizes. A wide variety is available, and discounts are offered for bulk purchases. Neodymium magnets can be custom-made in small quantities.

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.

Shipping nationwide on the same day from just one piece. Neodymium magnets are the strongest permanent magnets, allowing for miniaturization and thin designs. They are over eight times stronger than anisotropic ferrite magnets. In terms of shape, there are types with screwable countersunk holes. Discounts for bulk purchases are available, and we can discuss pricing. Neodymium magnets can be custom-made in small quantities. As for the applications of neodymium magnets, quantitatively, they are mostly used in various motors, MRI machines, and disk drives for magnetic recording devices. However, they are also used in a wide range of situations, including for displays, golf markers, magnetic fixtures, jigs, transportation, and experiments.
