Stainless Steel Bangle With 0.5 Micron TiN Layer & Hypoallergenic Properties
Product Spotlights
As a specialized jewelry manufacturer since 2010, Dongguan HonHo Jewelry leverages our 3,000-5,000 sqm facility and ISO9001-certified processes to engineer premium stainless steel bangles that merge aesthetic appeal with advanced material science. Our TiN-coated bangle delivers exceptional durability through aerospace-grade surface technology while guaranteeing hypoallergenic safety for sensitive skin – a critical solution for brands targeting quality-conscious markets across North America, Europe, and Asia.
Core Technology Breakdown:
- TiN Coating Advantage: A 0.5-micron vapor-deposited Titanium Nitride layer creates a surface hardness of 80+ HRC, significantly outperforming raw stainless steel (typically 50-55 HRC). This translates to:
- 10X greater scratch resistance vs. uncoated pieces
- Elimination of nickel leaching (primary allergen in jewelry)
- Permanent gold-toned luster unaffected by sweat or cosmetics
- Medical-Grade Substrate: Surgical 304 stainless steel core provides structural integrity and corrosion resistance, passivated to remove surface iron contaminants.
- Ergonomic Design: Seamless, rounded edges prevent skin irritation; internal curvature matches wrist anatomy.
Technical Specifications:
| Parameter | Standard Value | Customization |
| Coating Thickness | 0.5 μm ± 0.05 | 0.3-1.0 μm |
| Adhesion Strength | ISO Class 0 (No peeling) | N/A |
| Weight (6mm width) | 12-15g | Adjustable |
Commercial Benefits:
- Reduced Returns: Hypoallergenic certification lowers skin reaction complaints by 98% based on client data
- Inventory Longevity: TiN coating prevents tarnishing during storage, even in humid climates
- Brand Premium: Technical differentiation supports 20-30% higher price positioning vs. basic steel bangles

FAQ:
Q: How long does the gold color last?
A: The TiN coating is permanently bonded to the substrate through PVD (Physical Vapor Deposition), maintaining its hue for the product's lifetime under normal wear.
Q: Is it safe for people with metal allergies?
A: Yes. The combination of medical-grade 304 steel and TiN barrier prevents nickel exposure, complying with EU Nickel Directive 94/27/EC.
Q: Can you make smaller sizes for children?
A> We offer custom inner diameters from 45mm upwards. Contact us with specific measurements.
Q: What's the lead time for 2,000 pieces?
