Beryllium Copper Spring
Beryllium copper springs are elastic conductive contact components made from beryllium copper alloy (C17200/C17300) through precision stamping, heat treatment, and surface finishing. They offer excellent conductivity, elasticity, and fatigue resistance, with low contact resistance, stable spring force, and long service life. Ideal for battery contacts, connector terminals, switch contacts, shielding clips, and other applications.
