Why Gold-Filled?
✔ More durable than plating
✔ Legally requires 5% Съдържание на злато (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)

    • Отлична ковчежност

    • High corrosion resistance

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

    • Warmer gold-like hue

    • Better for intricate designs

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 & достъпност)

  2. S925 Silver Overlay (Ensures skin safety)

  3. Gold-Filled Layer (Adds luxury finish)


4. Gold Bath Electroplating Process (Стъпка по стъпка)

Стъпка 1: Preparing the Brass/S925 Base

  • Ултразвуково почистване (Removes oils & debris)

  • Acid Pickling (Removes oxidation)

Стъпка 2: Electroplating Bath Setup

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

  • Плътност на тока: 0.5-1 A/dm² (Controls plating thickness)

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

Стъпка 3: Plating the Earrings

  1. Initial Strike Layer (Thin gold adhesion layer)

  2. Main Plating (2.5-5Дебелина на µm)

  3. Post-Plating Rinse (Removes excess chemicals)

Стъпка 4: След обработка

  • Отгряване (Heat treatment for durability)

  • Полиране (Mirror or matte finish)


5. Контрол на качеството & Изпитване на издръжливост

A. Тестване на дебелината (XRF Analyzer)

  • Minimum 2.5µm gold layer (FTC compliance)

Б. Тестване на адхезия (Tape Peel Test)

  • Gold layer should not flake off

C. Устойчивост на опетняване (Тест със солен спрей)

  • 24-hour exposure to check corrosion resistance


6. Design Considerations for Gold-Filled Earrings

Популярни стилове

  • Обеци от обръч (Classic, high demand)

  • Обеци от шпилки (Минималистичен, Лек)

  • Dangle Earrings (Luxury appeal)

Опции за персонализиране

  • Акценти за скъпоценни камъни (Диаманти, CZ, раждащи камъни)


7. Устойчив & Ethical Manufacturing

Recycled Brass & Злато
Non-Cyanide Plating Alternatives
Fair-Trade Gold Sourcing


8. Common Challenges & Решения

Issue Решение
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

  • Персонализиран & Персонализирани дизайни

  • Eco-Conscious Jewelry Buyers
