Silver‑based materials such as pure Ag, AgNi and AgC have long been mainstream low‑voltage contact materials for relays, circuit breakers and switches, thanks to outstanding electrical and thermal conductivity. Recent sharp swings in silver and copper prices have brought profound challenges and shifts across the whole electrical‑contact industry.

Silver accounts for a large share of production costs for silver‑series contacts. When silver prices climb, manufacturers face heavy cost pressure and squeezed profit margins. Many producers have to adjust product prices or optimize internal processing to offset raw‑material risks. Copper, widely used in copper‑tungsten, copper‑chromium and other copper‑based composite contacts for medium‑ and high‑voltage applications, also sees its cost fluctuate with market quotes. Rising copper prices directly affect composite rivets and medium‑high‑voltage contact components.

Against such price turbulence, replacing partial silver‑based products with qualified copper‑based contact materials has become a major industry development direction. More customers tend to select copper‑tungsten composite rivets and copper‑chromium contacts which balance performance and cost. Manufacturers accelerate material formula upgrading and bimetal structure optimization, striving to maintain arc‑erosion resistance, breaking capacity and service life while cutting precious‑metal consumption.

Nevertheless, material substitution has technical limits. Key low‑voltage relay and circuit‑breaker contacts still rely on silver‑alloy materials to guarantee anti‑welding performance and reliable contact resistance. Market participants must closely track metal price trends, balance raw‑material inventory management and material‑scheme selection. At SHZHJ, we leverage our rich expertise in electrical contact materials to develop customized material solutions. We help our partners navigate raw‑material price volatility, achieving the optimal balance between stable product performance and controlled project costs.
