Expert Technical Insights & Partnership FAQ
For premium waterproof collections, we recommend Grade 5 Titanium, 316L Surgical Steel, and Tungsten Carbide. These materials are inherently non-corrosive. At Lonsin, we enhance this with horological-grade PVD Ion Plating (up to 5 microns), ensuring the finish withstands sweat, saltwater, and daily wear without fading, meeting the standards of high-end active-luxury brands.
Managing different thermal expansion rates is key. We utilize precision CNC grooving combined with a proprietary vacuum-pressure bonding process and specialized medical-grade resins. This ensures that inlays—whether natural wood, carbon fiber, or opal—remain seamlessly flush and structurally secure for the lifetime of the jewelry, even under extreme temperature changes.
It depends on your brand positioning. Grade 5 Titanium offers a higher prestige value due to its aerospace heritage and ultra-lightweight comfort (45% lighter than steel), allowing for higher retail margins. 316L Stainless Steel remains the industry standard for durable, high-volume fashion. Titanium is the preferred choice for brands targeting the "quiet luxury" modern elegance women's or high-performance men's niche.
Absolutely. Our commitment to safety begins at the source. We exclusively select materials from suppliers who provide documentation confirming compliance with global standards, including SVHC (REACH) and SGS testing protocols. By using these certified raw materials, we craft jewelry that is 100% lead-free, cadmium-free, and nickel-safe, aligning with the stringent chemical requirements of regulations like the EU REACH Regulation and California Prop 65. Furthermore, we provide complete material traceability to support your brand’s compliance efforts and ensure a confident entry into the global market.
