Stamping Beryllium Copper Forming Parts Copper
Products Description
The Stamping Beryllium Copper Forming Parts Copper, developed and manufactured based on decades of experience in power metal component processing, is the core conductive and elastic carrier inside new energy converter equipment, high-voltage relays, and power distribution socket modules. The entire component system is manufactured using a precision-bending and hollow stamping integrated molding process. It can be integrated into the assembly logic of a complete power architecture, including new energy storage PCS, vehicle-mounted electronic control systems, and DC power distribution units. As a key basic component for internal conduction, disconnection, and clamping, it undertakes multiple physical tasks such as current transmission, mechanical springback clamping, and contact closure buffering.
Material Advantages
Unique combination of high strength and conductivity
Custom Beryllium Copper Flat Spring is one of the few copper alloy materials that can maintain a 20% IACS level conductivity while achieving a tensile strength exceeding 1000 MPa. This makes it irreplaceable in scenarios requiring both structural support and current transmission.
Excellent Stress Relaxation Resistance
Under sustained or cyclic stress, beryllium copper exhibits a significantly lower stress relaxation rate than conventional elastic materials such as phosphor bronze and brass. This means that the BeCu Precision Stamping Electrical Connector Terminal Sheet can maintain its initial design contact force over a service life of several years, slowing down the increase in contact resistance.
Good Corrosion Resistance and Fatigue Resistance
Beryllium copper demonstrates excellent corrosion resistance in air, fresh water, and some weakly acidic media, superior to ordinary brass. Its high fatigue limit makes it suitable for Custom Beryllium Copper Flat Springs used in environments with frequent insertion/removal or mechanical vibration.
Main Product Features and Functions
Electrical Functions
Terminal Copper Beryllium Stamping Parts handle low-impedance current conduction within the system's internal circuits. The flat contact surface effectively reduces contact resistance, minimizing heat loss under high-current conditions and optimizing the energy conversion efficiency of the entire new energy device.
Mechanical Function
The BeCu Copper Stamping Part for Socket Accessories features a molded and bent structure that creates a stable and elastic clamping structure, providing constant positive pressure to relay contacts and socket contact points, thus mitigating contact issues caused by equipment vibration. The perforated and slotted structure optimizes stress distribution and extends the service life of the elastic reciprocating mechanism.
Structural Adaptability
The board surface has pre-set mounting holes of various sizes, allowing direct attachment to insulating bases, PCB boards, and relay plastic housings, adapting to modular assembly processes in system integration. The Custom Beryllium Copper Flat Spring, based on customized planar contours and bending shapes, can be customized in terms of size and opening positions according to integrators' system drawings, adapting to customized development projects for non-standard new energy electric control modules.
Manufacturing Process
Mold Design and Development
CAE simulation-assisted springback compensation design is used, addressing the anisotropy and springback characteristics of beryllium copper material through multi-station progressive die punch and die clearance and bending angle compensation design. Key dimension SPC control points are incorporated into the mold design stage.
01
Precision Stamping Forming
Utilizing a high-speed precision stamping press with progressive dies, multiple processes, including punching, bending, stretching, and embossing, are completed on a continuously fed strip. For the deep-drawing characteristics of Beryllium Copper Deep Drawn Stamping Parts, a multi-step deep-drawing process combined with intermediate annealing is employed to eliminate work hardening.
02
Heat Treatment
Solution treatment fully dissolves beryllium into the copper matrix, followed by rapid cooling to obtain a supersaturated solid solution. Aging treatment at 300~450℃ precipitates nanoscale strengthening phases, enabling sheet metal stamping parts such as BeCu Precision Stamping Electrical Connector Terminal Sheets to achieve final strength and elasticity, ensuring stable elasticity parameters without significant attenuation under long-term reciprocating deformation conditions in new energy systems.
03
Surface Treatment
Silver plating, gold plating, tin plating, or anti-oxidation treatments are available according to application requirements to optimize contact resistance, solderability, and corrosion resistance. The plating thickness and adhesion have been tested and verified. This standardized surface treatment process is also compatible with BeCu Copper Stamping Part for Socket Accessories, ensuring stable conductivity of the beryllium copper stamped components in high and low temperature, high current operating environments.
