OEM kumush zargarlik buyumlari: Nikohsiz, Qattiq, Tarnish & Suvga chidamli tugaydi

Kirish

In today’s jewelry market, iste'molchilar nafaqat estetik joziba, balki xavfsizlikni ham talab qiladi, chidamlilik, va hipoalerjenik xususiyatlari.

Anti-Tarnish Silver Alloys (Kumush) Germanium reduces sulfur reaction Tabiiy ravishda tarashga chidamli, no coating needed
Benzotriazole (BTA) Pazasi Chemical dip forms a protective molecular layer Extends shine between cleanings

3.3 Testing Tarnish Resistance

  • Tuz püskürtülen testi (ASTM B117) – Simulates years of wear in 24–48 hours.

  • Sulfur Chamber Test – Accelerates tarnish formation for quality checks.

4. Water-Resistant Jewelry

4.1 Why Water Resistance Matters
