Gold Plated Round Magnets

Gold Plated Round Magnets are sleek, durable magnetic discs coated with a thin layer of gold for enhanced aesthetics and corrosion resistance. Ideal for crafts, DIY projects, or industrial applications, these magnets combine functionality with a luxurious finish. The gold plating adds a premium touch while maintaining strong magnetic properties. Available in various sizes and strengths, they are perfect for jewelry, displays, or securing lightweight items. Their smooth, polished surface ensures scratch resistance and a refined appearance. Whether for decorative or practical use, these magnets offer versatility and elegance in one compact design.

Gold Plated Round Magnets: Premium Performance and Aesthetic Appeal

Gold plated round magnets combine superior functionality with an elegant finish, making them ideal for industrial, commercial, and decorative applications. Here are 4-6 key features with technical specifications:
1. High Magnetic Strength: These magnets typically feature neodymium (NdFeB) or samarium-cobalt (SmCo) cores, offering surface magnetic fields ranging from 3,000 to 12,000 Gauss, depending on grade (e.g., N35 to N52 for NdFeB). The gold plating doesn't compromise performance, maintaining 90-95% of the base material's flux density.
2. Corrosion-Resistant Coating: The 24K gold electroplating (2-5μm thickness) provides excellent oxidation resistance, withstanding 500+ hours in salt spray tests (ASTM B117) compared to uncoated magnets. The nickel underlayer (3-8μm) enhances adhesion and durability.
3. Precision Dimensions: Manufactured to tight tolerances of ±0.05mm on diameter and ±0.1mm on thickness, these magnets are available in standard sizes from 3mm to 30mm diameter, with axial magnetization for optimal pull force.
4. Temperature Stability: Gold plated NdFeB variants operate from -40°C to +150°C (up to +200°C with special grades), while SmCo versions extend to +250°C, with minimal flux loss (<5% at 100°C).
5. Decorative Versatility: The 0.2-0.5μm gold layer achieves a lustrous finish with 85-90 light reflectance units (LRV), suitable for jewelry displays and high-end fixtures without tarnishing.
6. Customizable Options: Available with epoxy coatings (0.1-0.3mm) beneath gold plating for enhanced impact resistance (IK08 rating), or with custom logos (50μm engraving depth) for branding applications.

Applications

1. Jewelry & Fashion Accessories

Gold plated round magnets serve as elegant closures for bracelets, necklaces, and magnetic earrings. Their luxurious appearance enhances high-end fashion items while providing secure magnetic functionality.

2. Electronics & Gadgets

Used in premium smartphone cases, wireless chargers, and magnetic mounting systems, these magnets combine aesthetic appeal with technical performance. The gold plating resists corrosion better than standard magnets.

3. Promotional Products

Ideal for luxury-branded giveaways and corporate gifts, gold plated magnets can display logos or artwork while functioning as refrigerator magnets or document holders in executive offices.

4. Industrial Applications

In specialized manufacturing, these magnets provide non-marring surfaces for delicate material handling. The gold plating prevents oxidation in cleanroom environments or medical device assembly.

5. Home Decor

Used as decorative magnetic push pins for memo boards or as invisible mounting solutions for framed artwork, the gold finish blends with upscale interior designs while maintaining strong holding power.
