Sheet Metal Parts Beryllium Copper Spring Contact
Products Description
Sheet Metal Parts Beryllium Copper Spring Contacts are elastic conductive structural components made from copper-beryllium alloy as the base material, manufactured through precision stamping and aging strengthening processes.
Their core characteristics are:
Simultaneously possessing spring properties and conductive properties; Not easily subject to permanent deformation after long-term operation; Stable contact pressure; Excellent fatigue resistance; Suitable for high-frequency operating environments; Capable of complex structural designs.
Therefore, beryllium copper is considered one of the important materials for high-end elastic conductive components in relays and switches.

Key Features and Product Advantages: Infusing Precision Switches with Long-Term Certainty
Constant Contact Pressure, Eliminating Loose Connections
Extremely high anti-relaxation characteristics ensure that even after ten years of service and millions of cycles, the moving contact pressure remains above 90% of its initial value, eliminating the risk of increased contact resistance and overheating due to insufficient pressure.
High-Frequency Response, Enhancing Control Precision
Low hysteresis and high rebound characteristics result in crisp and clean switching action without "trailing" arcs, crucial for millisecond-level decision-making and protection in automotive control units.
Miniaturization and Integration, Facilitating Lightweight Design
Utilizing the high strength of Sheet Metal Parts Beryllium Copper Spring Contact, we can design thinner and narrower springs, achieving stronger contact force and current-carrying capacity within the same or even smaller volume, contributing to the miniaturization and lightweight development of modern relays and connectors.
Weather and corrosion resistant, adaptable to harsh environments
The excellent physical and chemical stability of Terminal Copper Beryllium Stamping Parts allows them to maintain stable mechanical properties in harsh industrial and automotive environments, such as high temperature and humidity, salt spray, and oil contamination, without the need for complex protective shells.
Production Process Flow
Precision Slitting and Leveling: Beryllium Copper Stamping for Electrical Connector is slitted to the designed width, and residual stress in the coil is eliminated by a precision leveling machine.
High-Speed Progressive Die Stamping: Multi-station continuous die, sequentially completing processes such as guiding, punching, blanking, and bending;
Deburring and Finishing: Removing microscopic burrs from the punched surface to ensure all edges of the spring are smooth and free of sharp corners;
In-Die Riveting Integration (Applicable Components): CCD positioning + high-speed riveting to complete the in-die assembly of contacts and armatures;
Vacuum Aging Heat Treatment: Using a protective atmosphere aging furnace, holding at 315℃±5℃ for 2~2.5 hours;
Surface Treatment: Beryllium Copper Stamped Parts Providing surface treatments such as nickel plating/silver plating/passivation according to customer requirements to improve weldability and corrosion resistance;
