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.
