What Is KDM Gold? Understanding Its Composition and Uses

Learn what KDM gold is, its composition of 92% gold and 8% cadmium, and why its use has declined due to health concerns.

297 views

KDM gold refers to gold alloyed with other metals where the solder used is of the same karat (purity level), specifically 92% gold and 8% cadmium. This combination ensures consistent purity across the jewelry piece. However, due to health and environmental concerns related to cadmium, its use has been largely reduced in favor of other materials.

FAQs & Answers

  1. What does KDM stand for in KDM gold? KDM stands for a type of gold alloy where the solder used matches the karat purity of the gold, commonly 92% gold and 8% cadmium.
  2. Why is cadmium used in KDM gold? Cadmium is alloyed with gold in KDM gold to ensure soldering at the same karat level, providing consistent purity across the jewelry piece.
  3. Are there any health concerns with KDM gold? Yes, cadmium is toxic and poses health and environmental risks, leading to reduced use of KDM gold in favor of safer alternatives.
  4. What alternatives exist to cadmium in gold alloys? Jewelry makers now often use other metal alloys and solders without cadmium to avoid its harmful effects while maintaining gold purity.
