Product Advantages
Ensure Stable Electrical Connection
The high-purity copper material and precision stamping process of Copper Sheet Stamping for Electric Relays guarantee a surface flatness of Ra≤0.4μm and a stable contact resistance at the microohm level, avoiding poor contact and heat loss caused by surface unevenness. In the application of relay shrapnels, this low-resistance characteristic ensures lossless current conduction, and the high flatness guarantees uniform contact pressure, extending the on-off service life of equipment.
Adapt to High-Frequency Application Scenarios
Cryogenic annealing and flattening treatment completely eliminate stamping residual stress. High Precision Connecting Copper Sheet Metal Stampings boast a fatigue resistance life of over one million cycles, maintaining structural stability without deformation or fracture even in high-frequency on-off or vibration scenarios. Compared with untreated Copper Part Stampings, their fatigue resistance is improved by more than 40%, meeting the long-term operation requirements of industrial automation and new energy vehicles.
Adapt to Diverse Scenarios
High-speed precision stamping presses combined with micron-level tolerance molds can process complex structures such as special-shaped holes, bends, and raised bosses, adapting to diverse demands ranging from micro connectors to large busbars. High Precision Progressive Stamping Copper Parts in the same batch feature excellent dimensional consistency, which can be directly adapted to automatic assembly equipment and improve production efficiency.
Strong Adaptability to Complex Environments
The surface can be provided with protective treatments such as silver plating, tin plating, and passivation. Silver plating enhances sulfidation and arc resistance, tin plating improves corrosion resistance, and passivation forms a dense oxide film. In complex environments such as outdoor and vehicle-mounted settings, Copper Stamping Electrical Precision Parts show no significant performance attenuation, ensuring the long-term stable operation of equipment.
Product Features
High Ductility for Complex Stamping, Crack-Free Forming
Copper Sheet Metal Stamping Bending Parts are made of high-purity electrolytic copper/oxygen-free copper base material with excellent metallic ductility, which can be easily adapted to complex processes such as special-shaped bending, micro-hole stamping, and embossing forming. There is no cracking or wrinkling during the stamping process, and the designed structure can be accurately formed without subsequent trimming. It meets the diverse precision forming requirements of micro connectors, special-shaped shrapnels, and other components.
Excellent Thermal and Electrical Conductivity for Multi-Scene Applications
Copper Sheet Stamping for Electric Relays not only features high electrical conductivity close to pure copper to ensure low-resistance and lossless current transmission, but also has outstanding thermal conductivity that can quickly dissipate the heat generated during the operation of electrical equipment, avoiding component damage caused by local overheating. With the dual functions of conduction and heat dissipation, it is suitable for scenarios requiring both thermal and electrical conductivity, such as power modules and busbars.
Environmentally Compliant for Global Procurement Standards
All High Precision Connecting Copper Sheet Metal Stampings adopt eco-friendly base materials and surface treatment processes, and strictly comply with international environmental standards such as RoHS and REACH with no residual harmful impurities. Meanwhile, they have obtained ISO9001 and IATF16949 quality certifications, which can directly meet the compliance requirements of global buyers without additional environmental testing, reducing the procurement compliance costs.
Application Scenarios
Relays and Contactors
As the core carrier of relay shrapnels, Copper Part Stampings feature high elasticity and fatigue resistance to ensure stable contact pressure, as well as low-resistance conduction to reduce energy loss, making them suitable for high-frequency on-off scenarios in industrial automation and new energy vehicles.
High-Voltage Systems of New Energy Vehicles
Applied in battery pack busbars and motor controller copper bars, High Precision Progressive Stamping Copper Parts are made of oxygen-free copper to enable high-current and low-resistance conduction, and their vibration resistance adapts to the complex working conditions of vehicle mounting, serving as key precision components for the entire vehicle power system.
PCB Connectors and Consumer Electronics
Used in PCB connectors of smartphones and tablets, Copper Stamping Electrical Precision Parts adopt a miniaturized and flat structure to fit high-density layout, and their precise dimensional control improves assembly efficiency, acting as a core support for the miniaturization of consumer electronics.
Industrial Control and Power Modules
In frequency converters and power modules, Stamped Copper Sheets with high thermal conductivity perform both heat dissipation and supporting functions. Stress relief treatment ensures long-term operational stability, adapting to the continuous working requirements of industrial equipment.
