Beryllium Copper Stamping Services
Products Description
Beryllium copper stamping services refer to the professional manufacturing services that use beryllium copper alloy strip as raw material and process it into precision electrical connection structural components such as relay moving springs, elastic contacts, and conductive springs through high-precision progressive die stamping technology. Its most typical application scenario is the moving spring in industrial control relays, which determines whether the relay can maintain stable contact resistance and operating force in hundreds of thousands of opening and closing operations.
Technical Features
Performance-Oriented Customized Heat Treatment
We not only perform standard heat treatments but also customize under-aging, peak-age, or over-aging processes based on the final service conditions of the beryllium copper sheet metal forming (such as operating temperature and stress state), finding the optimal balance between strength, conductivity, and relaxation resistance.
Residual Stress Management and Optimization
Stamping and heat treatment introduce residual stress. We adjust residual stress to a favorable state (such as surface compressive stress) through special vibration aging, low-temperature heat treatment, or shot peening processes, thereby significantly improving the fatigue strength and stress corrosion resistance of BeCu components.
Functional Electroplating and Coating
We provide differentiated surface treatments for different functional areas for beryllium copper parts. For example, thick gold or palladium-nickel alloy plating is used on contact areas to ensure low contact resistance and corrosion resistance; tin or tin-lead alloy plating is used on solder areas; and low-cost passivation is performed on non-functional areas. We also ensure that the plating adheres firmly to bending and harsh environments.
Material Properties and Advantages
High Strength and Hardness
After aging for High conductivity copper stamping, the tensile strength can reach 1000-1500 MPa, and the hardness reaches HV 350-420, which is the strength level of spring steel, but with lower density and no magnetism.
Excellent Elastic Properties
Extremely high elastic limit and extremely low elastic hysteresis ensure that Conductive copper alloy stamping hardly undergoes permanent deformation during repeated deformation, resulting in low energy loss.
Excellent Resistance to Stress Relaxation
Under long-term stress or high temperatures (such as 150°C), the copper alloy precision stamping's elastic force decay rate is extremely low, which is key to ensuring long-term contact reliability.
Frequently Asked Questions
Can Beryllium copper stamping process customize non-standard sizes of moving springs?
Yes. We can customize the bending angle, contact position, thickness, and mounting structure according to the customer's specific relay drawings to achieve precise fit.
Must beryllium copper sheet metal forming undergo precious metal plating?
Silver plating is an option for signal control scenarios. Gold plating is recommended for high-power loads or high-humidity salt spray environments. Passivation treatment is available for ordinary operating conditions.
Can this BeCu components stamping service meet the needs of large-scale automated assembly overseas?
Yes. The batch of finished products exhibits high consistency in size, elasticity, and plating, with a clean, burr-free surface, fully compatible with fully automated assembly lines.
