When sourcing magnetic bracelets and necklaces, the base material is critical for durability and skin safety. 316L Stainless Steel is the industry standard for high-end pieces due to its corrosion resistance and hypoallergenic properties. For premium markets, Titanium is preferred for its lightweight nature and superior strength. Ensure the magnets used are High-Strength Neodymium (Rare Earth) magnets, typically rated at 2,000 to 3,000 Gauss per magnet for therapeutic effectiveness. Additionally, verify that any plating (such as 18K Gold or IP Black) uses Ion Plating (IP) technology, which is significantly more durable than traditional electroplating.
