1/4 x 1/4 Inch Neodymium Rare Earth Gold Plated Magnetic Clasp N42 (1 Pair Pack) Description

These neodymium magnetic clasps utilize sintered NdFeB alloy with a 42 MGOe energy product. Each 6.35 mm diameter clasp features a low-profile 1.8 mm thickness and a precision-engineered push-pull mechanism for single-handed operation. The triple-layer gold-nickel-copper plating ensures hypoallergenic skin contact and withstands 500+ hours of salt spray testing (ASTM B117), preventing tarnish in humid environments. The male/female pair generates a ≥1.2 kg holding force while requiring only 0.4–0.6 kg to separate, balancing security with user accessibility. Thermal stability is maintained up to 80°C, with gold plating enhancing conductivity for EMI-sensitive applications. Rounded edges and polished surfaces prevent fabric snagging.

1/4 x 1/4 Inch Neodymium Rare Earth Gold Plated Magnetic Clasp N42 (1 Pair Pack) Applications

Jewelry: Necklace closures, bracelet ends, and anklet connectors.

Medical Wearables: Secure fasteners for patient monitors and wearable sensors.

Luxury Accessories: Handbag clasps, watch bands, and eyewear retention.

Apparel: Magnetic buttons for adaptive clothing and outerwear.

Consumer Tech: Latch systems for VR headsets and travel gadgets.

1/4 x 1/4 Inch Neodymium Rare Earth Gold Plated Magnetic Clasp N42 (1 Pair Pack) Packaging

To ensure safety during transportation and compliance with shipping regulations, all magnets are securely packed with a metal shielding layer inside the box. This prevents magnetic interference with surrounding items and protects the product from external damage.

Packaging: Carton, Wooden Box, or Customized.

1/4 x 1/4 Inch Neodymium Rare Earth Gold Plated Magnetic Clasp N42 (1 Pair Pack) FAQs

Q1. Can they hold heavy pendants?

Max. vertical load: 1.2 kg. For pendants >15g, reinforce with secondary security (e.g., lobster clasp).

Q2. Do magnets interfere with pacemakers?

Maintain >15 cm distance. Field strength at 2 cm: <10 Gauss (below FDA 5 Gauss/cm threshold).

Q3. Can plating wear off with friction?

Gold layer withstands 500+ abrasion cycles (ASTM D4060). Avoid ultrasonic cleaners with abrasive solutions.

1. Common Preparation Methods

The clasps are manufactured by sintering NdFeB powder under a 1.8 T magnetic field at 1,080°C. Precision-ground discs are drilled with alignment holes for assembly. Gold plating involves electrolytic nickel-copper undercoating (5–8 μm) followed by immersion gold (0.2–0.5 μm). Male/female components are press-fitted with stainless steel spring mechanisms, then laser-welded for structural integrity. Each pair undergoes force testing (0.4–0.6 kg opening / ≥1.2 kg holding) and rotational alignment verification before encapsulation in nitrogen-flushed anti-tarnish packaging.
