Why Gold-Filled?
✔ More durable than plating
✔ Legally requires 5% 금 함량 (US FTC standard)
✔ Does not flake or wear off easily

2. Selecting Premium Brass Alloy for Base Metal

Best Brass Alloys for Gold-Filled Earrings

  1. C260 (Cartridge Brass – 70% Cu, 30% Zn)

    • Excellent malleability

    • High corrosion resistance

  2. C220 (Commercial Bronze – 90% Cu, 10% Zn)

    • Warmer gold-like hue

    • 복잡한 디자인에 더 좋습니다

Why Not Pure Copper?

  • Too soft for long-term wear

  • Prone to oxidation

3. The Role of S925 Silver in Gold-Filled Jewelry

When to Use S925 Silver as a Base

  • For hypoallergenic earrings (Nickel-sensitive customers)

  • Higher-end collections (Sterling silver adds value)

How Brass & S925 Silver Work Together

  1. Brass Core (Provides structure & 경제성)

  2. S925 Silver Overlay (Ensures skin safety)

  3. Gold-Filled Layer (Adds luxury finish)

4. Gold Bath Electroplating Process (Step-by-Step)

단계 1: Preparing the Brass/S925 Base

  • 초음파 청소 (Removes oils & debris)

  • Acid Pickling (Removes oxidation)

단계 2: Electroplating Bath Setup

  • Gold Solution: 14K-18K gold cyanide bath

  • 전류 밀도: 0.5-1 A/dm² (Controls plating thickness)

  • Temperature: 120-140° F (50-60° C)

단계 3: Plating the Earrings

  1. Initial Strike Layer (Thin gold adhesion layer)

  2. 메인 도금 (2.5-5µm 두께)

  3. Post-Plating Rinse (Removes excess chemicals)

단계 4: Post-Processing

  • 가열 냉각 (Heat treatment for durability)

  • 세련 (Mirror or matte finish)

5. 품질 관리 & 내구성 테스트

에이. 두께 테스트 (XRF Analyzer)

  • Minimum 2.5µm gold layer (FTC compliance)

비. Adhesion Testing (Tape Peel Test)

  • Gold layer should not flake off

기음. 변색 저항 (염수분무시험)

  • 24-hour exposure to check corrosion resistance

6. Design Considerations for Gold-Filled Earrings

Popular Styles

  • 후프 귀걸이 (권위 있는, high demand)

  • 스터드 귀걸이 (미니멀리스트, 가벼운 중량)

  • 귀걸이를 다해 (Luxury appeal)

사용자 정의 옵션

  • 조각 (Laser or hand-engraved details)

  • 보석 액센트 (다이아 패 한 벌, CZ, Birthstones)

7. 지속 가능한 & 윤리적 제조

✔ 재활용 황동 & 금
✔ Non-Cyanide Plating Alternatives
✔ Fair-Trade Gold Sourcing

8. Common Challenges & Solutions

Issue 해결책
Uneven Plating Adjust current density
Gold Wear Over Time Use thicker plating (5µm+)
Allergic Reactions Ensure nickel-free brass

9. Market Trends in Gold-Filled Jewelry

  • Rising Demand for Affordable Luxury

  • 사용자 정의 가능 & 개인화 된 디자인

  • Eco-Conscious Jewelry Buyers
