Gold-Plated Material Recycling
Key Parameters of Gold-Plated Materials
Conductivity: Resistivity 1.6 μΩ·cm, ensuring high-frequency signal integrity.
Vickers hardness: 70-140 HV.
Industrial coating thickness: 5-20 μm.
High-temperature wire silver plating withstands -80℃~250℃;
Electronic coatings operate at ≤150℃.
Environmental compliance: Cyanide-free process with copper ion residue <10mg/L, RoHS certified.
The applications of gold-plated materials partially overlap with silver-plated materials. For example: in the electronics industry, USB connectors and relays use gold-plated layers to ensure high conductivity, as do gold-plated jewelry. Gold-plated materials have broader applications: semiconductor 5G chip packaging employs gold-plated silver wires; in aerospace, gold-plated materials are used for satellite sensors and avionics; in the medical field, gold-plated materials serve in pacemaker electrodes. Gold-plated material recycling prices are significantly higher than silver-plated materials.
