Our custom gold plated beryllium copper compression springs are precision manufactured for high-performance electrical and mechanical contact applications. Made from premium beryllium copper wire, these straight leg conductive springs combine excellent electrical conductivity, high elasticity, and fatigue resistance. The pre-nickel underlayer followed by gold plating ensures low contact resistance, superior corrosion resistance, and stable performance in demanding environments. Every electronic contact spring is produced via precision CNC spring coiling, ensuring consistent pitch, outer diameter, and spring force. The straight legs are precision formed to meet specific installation and connection requirements. After forming, each spring undergoes ultrasonic cleaning, pre-nickel plating, and gold plating to enhance conductivity and durability. As a dedicated manufacturer, we offer full OEM and custom service, allowing customization of wire diameter, coil count, outer diameter, free length, leg configuration, and plating finishes to match your exact application needs. These gold plated contact springs are ideal for creating reliable, low-resistance electrical connections in various precision assemblies.
