5mm x 5mm x 1mm Neodymium Thin Square Block Magnet – N55 Grade 

Key Features:

• Dimensions: 5mm Length × 5mm Width × 1mm Thickness
• Ultra-Low Profile: Near-invisible 1mm depth for flush surface inlay and restricted-clearance applications
• Anti-Pivot Design: Square geometric profile provides excellent lateral stability and prevents twisting/pivoting
• Precision Tolerance: ±0.05mm 
• Magnet Grade: N55 – The highest commercial grade available, yielding unmatched flux density per unit volume
• Pull Force: Approx. 0.79 lb
• Coating: Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer plating for a durable, professional finish
• Magnetization: Axially magnetized (Poles on the flat square faces)

Material Description:

Our 5mm x 5mm x 1mm N55 thin square block magnets represent the absolute pinnacle of high-flux commercial rare earth engineering. Designed for tight design envelopes where space is severely limited, the premium N55 composition ensures that this micro block delivers significantly more magnetic force than standard N35 or N42 magnets of identical dimensions. The straight, square edges make them incredibly easy to align side-by-side or drop into matching chiseled channels or molded pockets. These blocks can be seamlessly embedded into shallow routed cavities, precision-molded plastics, or luxury paperboard packaging using high-performance epoxy or acrylic adhesives, providing a clean, completely concealed magnetic latching point.

Handling Advice: CRITICAL NOTICE: Elite N55 micro-thin magnets require exceptional handling care. Sintered neodymium is inherently brittle like glass, and at a mere 1mm thickness, these wafers can crack or fracture easily if subjected to bending stress, improper tool impact, or high-velocity snap collisions. The sharp corners of a square profile are especially vulnerable to chipping. Never allow these magnets to slam together freely from a distance. To minimize damage risk during assembly, always separate individual pieces by sliding them off the stack rather than pulling them apart vertically.

Warnings and Safety Information:

• Fragility Hazard: Ultra-thin profile with sharp corners. High impact from snapping together or dropped handling WILL fracture or chip the block.
• CHOKING HAZARD: Micro-sized profile poses a severe danger to children and pets. Keep strictly secured.
• Ingestion Warning: Swallowed magnets can attract through internal tissue walls, causing fatal complications. SEEK IMMEDIATE MEDICAL ATTENTION if ingested.
• Medical Safety: KEEP AWAY from pacemakers and sensitive medical implants at all times.

Applications:

• Near-invisible hidden closures for luxury cosmetic boxes, premium jewelry cases, and high-end presentation folders
• Concealed alignment closures and anti-twist tabs for high-end micro-electronics and smart wearable technology
• Precision magnetic indexing, linear track alignments, and swappable components for tabletop gaming miniatures
• Micro sensory triggers, reed switch activations, and low-clearance Hall-effect arrays in industrial automation
• Shallow flush-mount attachment points for thin 3D-printed square enclosure panels, lids, and access plates
