Designed for heavy-duty holding, mounting, and retrieval applications, each magnet features a powerful NdFeB (Neodymium-Iron-Boron) core encased in a steel cup housing that amplifies magnetic force and shields the sides from chipping or demagnetization. With a black epoxy coating, these magnets resist moisture, oil, and chemical exposure — ideal for workshops, factories, garages, laboratories, and outdoor industrial environments where both performance and corrosion protection are essential. Built for Superior Holding Power The secret behind the strength lies in the cup design. Unlike a bare magnet, the steel pot concentrates the magnetic flux toward the open face, increasing the pulling force up to 3.5× stronger than a standard neodymium disc of the same size. Under ideal conditions — clean, flat, thick, unpainted steel — a 1.8" epoxy-coated cup magnet can deliver 90–100 pounds of direct pull strength. The steel housing also prevents lateral demagnetization and protects the magnet from mechanical stress, ensuring long-term reliability even under vibration or repeated mounting cycles. Epoxy Coating – Advanced Corrosion Defense Each cup magnet is sealed with a durable black epoxy finish — an upgrade from conventional nickel coatings. The epoxy layer forms a watertight barrier that: 🛡️ Prevents corrosion and oxidation in humid or outdoor environments. 💧 Protects against oils, salt air, and mild chemicals. ⚙️ Resists chipping and cracking during installation and use. 🎨 Provides a professional matte black finish for clean visual integration in equipment or displays. This coating is ideal for marine, industrial, or outdoor applications where typical nickel coatings can degrade. Precision Engineering and Quality Control Applied Magnets ensures that each cup magnet meets ISO-certified production standards for dimensional precision, plating thickness, and magnetic field consistency. Every 1.8" magnet undergoes: Field-strength testing to confirm consistent magnetic flux. Coating inspection for surface integrity and thickness. Pull-force validation under controlled lab conditions. The result is a magnet that performs with exceptional reliability across all environments. Technical Specifications Feature Specification Outer Diameter (OD) 1.8 inch (≈45 mm) Thickness 0.27 inch (≈7 mm) Material Neodymium-Iron-Boron (NdFeB) + Steel Cup Coating Black Epoxy Magnet Grade N35 Equivalent Pull Force (Ideal) 90–100 lbs Operating Temperature Up to 176°F (80°C) Mount Type Countersunk Hole with Screw Included 6 Magnets + 6 Screws Brand Applied Magnets How the Cup Magnet Works A bare neodymium magnet emits flux in all directions. When encased in a steel cup, the flux lines are captured and redirected to one face. This intensifies the field on the open side, producing higher surface force while minimizing stray fields on the back. This makes cup magnets perfect for: Vertical mounting applications where shear resistance is critical. Retrieval tools that need maximum grip with minimal size. Secure magnetic mounts for signs, fixtures, sensors, or cameras. Industrial & Commercial Applications Built for performance and versatility, these magnets serve hundreds of practical uses across multiple industries: ⚙️ Manufacturing & Engineering Mount or align steel fixtures and components. Secure tools, jigs, and gauges in fabrication lines. Create quick-release magnetic mounts for equipment. Replace mechanical fasteners in repetitive setups. 🧰 Workshop & Garage Organize tools, screws, and bolts with magnetic mounting. Attach LED lights, cameras, or hooks to metal beams.
