Beryllium Copper Stamped Contacts – High Reliability for Sensor & 5G Modules
Tingfeng Hardware provides beryllium copper stamped contacts, specifically designed for high-reliability applications such as sensors and 5G modules. Beryllium copper (C17200) offers excellent elasticity, fatigue resistance, and conductivity, making it ideal for high-frequency signal transmission and repeated mating scenarios. Contacts undergo precision progressive die stamping and stress relief heat treatment, ensuring force stability and signal integrity over long-term use. With 16 years of precision manufacturing experience, we provide high-reliability stamping solutions for the communication and sensing industries.
Product Description
Beryllium copper stamped contacts, with their excellent stress relaxation resistance and fatigue resistance, have become the preferred contact material in 5G communication, sensors, and high-frequency connectors. Our contacts are formed through precision progressive die stamping, with die clearance controlled at 5%-8% of material thickness, ensuring smooth sheared surfaces and precise dimensions. Gold or silver plating effectively reduces contact resistance, ensuring stable high-frequency signal transmission. Each contact undergoes 100% force testing and dimensional inspection, suitable for demanding applications requiring millions of reliable contacts.
