Product Introduce
🔹 Magnetic Core – Neodymium Iron Boron (NdFeB)
The magnetic core is made of high performance NdFeB material, compact yet providing powerful attraction. N35 to N52 grades are available to suit different tensile strength and temperature requirements.
🔹 Steel Cup – Stainless Steel
The precision machined steel cup concentrates magnetic flux on a single surface, enhancing tensile strength while protecting the delicate NdFeB core from cracking or breakage.
🔹 Black Coating – Epoxy Plating
The entire surface of the high strength pot magnet is covered with a black epoxy coating, offering excellent water and corrosion resistance and a clean, matte finish. Suitable for humid or mildly corrosive environments.
🔹 Countersunk Hole Design – Screw Holes
Countersunk screws can be used for flush mounting, ensuring a secure and stable installation without easy displacement.
🔹 Available Models – SNA/LNA Series

Usage & Applications
🔹 Three ways to use this pot magnet:
1️⃣ Screw Mounting for Permanent Installation – Use the countersunk hole with screws to securely attach the magnet to metal or non metal surfaces for a long-lasting, permanent setup.
2️⃣ 3M Adhesive Mounting for Rotation Prevention – Apply the built in 3M adhesive to metal or non metal surfaces to fix the powerful round pot magnet in place, preventing rotation while keeping installation quick and easy.
3️⃣ Temporary Use on Metal Surfaces – Place the magnet directly on metal surfaces for short term applications. The strong magnetic force holds it in place without leaving marks or residue.
🔹 These black epoxy resin pot magnets feature 3M adhesive backing and are versatile enough for various applications:
• Industrial and workshop: Secure tools, jigs, fixtures, or machine parts during assembly, maintenance, or production.
• Commercial and retail: Mount signage, display boards, or promotional materials on metal or non-metal surfaces.
• Home and office: Quickly and cleanly install hooks, storage shelves, boards, or decorative panels.
• Rotation sensitive applications: Secure round magnets with the adhesive backing to prevent accidental rotation or displacement.
