Silver Contact Materials Guide 2026: AgSnO2 vs AgNi Performance & Selection

Chapter 1: The Invisible Heart of Power Systems

At CD Silver (cdsilver.com), we ensure reliability in 1500V PV systems and High-Current relays through precision engineering.

Chapter 2: AgSnO2 - The Superior RoHS Replacement

Silver Tin Oxide (AgSnO2) is the definitive successor to AgCdO. Our internal oxidation process prevents contact welding in extreme DC loads.

Chapter 3: AgNi - Precision for Control & Signal

For high-frequency switching and low contact resistance, Silver Nickel (AgNi) is the benchmark material.
