• Thickness comparable to a sheet of paper, yet magnetically robust
• Customizable grade options (N35 to N52) to suit your specific magnetic requirements
• Various surface treatment options available for enhanced durability

A good choice for micro-robotics and miniature sensors to ultra-thin electronic devices and cutting-edge medical implants.

These tiny disc magnets open up a world of possibilities in applications where every fraction of a millimeter counts.

Explore our detailed specifications below to tailor these microscale magnetic wonders to your exact needs.

1. Material Grades

For optimal performance at this small size, we recommend:

Preferred Grades:

• N50, N52, N54
• These higher-grade options ensure sufficient pull force despite the compact dimensions

Available Grades:

• N35 to N54 (full range: N35, N38, N40, N42, N45, N48, N50, N52, N54)

Temperature Grades:

• Standard (up to 80°C)
• H (120°C): For moderate heat exposure
• SH (150°C): Suitable for automotive applications
• UH (180°C): Ideal for industrial environments
• EH (200°C), AH (220°C), TH (240°C): For extreme temperature conditions

2. Dimensions

Standard Size:

• Diameter: 5mm (±0.05mm tolerance)
• Thickness: 0.5mm (±0.05mm tolerance)

Customization Potential:

• Minimum size: 0.2mm for either diameter or thickness
• Precision tolerances available for specialized applications

3. Surface Treatments

Default:

• Nickel-Copper-Nickel (Ni-Cu-Ni) triple-layer plating

Alternative finishes:

Parylene Coating:

• Recommended for strict tolerance control
• Ultra-thin, uniform layer
• Excellent for maintaining precise dimensions

Other Surface Treatments:

• Zinc (Zn): For enhanced corrosion resistance
