Product Description The 18mm x 2mm Neodymium Disc Magnet is an ultra-slim, high-power magnetic solution designed for applications where space is extremely limited but a strong hold is required. With an 18mm diameter and only 2mm thickness, it offers a sleek, low-profile footprint. Each magnet features a premium Ni-Cu-Ni triple-layer coating to prevent corrosion and provide a smooth, professional silver finish.

Key Features

Ultra-Thin Profile: Only 2mm thick, making it perfect for recessed mounting and hidden closures.
High Pull Force: N35 grade neodymium provides a powerful grip despite its minimal height.
Corrosion Resistant: Triple-layer nickel plating protects the brittle core from moisture and oxidation.
Axial Magnetization: The poles are located on the flat circular faces for maximum surface contact.
Lightweight: Ideal for portable electronics, lightweight robotics, and hobbyist models.

Technical Details

Material: Sintered NdFeB.
Max Operating Temp: 80°C.
Dimensional Tolerance: ±0.1mm.

Prototyping and Engineering Tips from Robogears

Hidden Paper/Fabric Latches: Because these are so thin, they are excellent for magnetic brochures, boxes, or clothing closures. They can be glued behind a thin layer of paper or fabric and still provide a reliable "snap."
Glue Recommendations: Use a high-quality cyanoacrylate (super glue) or thin epoxy. Since the magnet is very thin, ensure the mounting surface is perfectly flat to maximize the bonding area.
Handling Brittle Materials: Neodymium magnets are fragile. Do not let them snap together from a distance; the 2mm thickness makes them particularly prone to cracking under high-impact collisions.
Mounting in 3D Prints: This 18x2mm size is a standard for 3D-printed magnetic connectors. Design a 18.2mm wide by 2.1mm deep circular pocket in your CAD model for a perfect press-fit or glue-in installation.
