Products Description
Custom Metal Stampings are key fundamental components of modern electrical control systems, providing precise and reliable current transmission and mechanical connection functions for electrical equipment such as relays, switches, contactors, and fuses. Our products are not merely simple metal parts, but rather optimized carriers of electrical and mechanical performance through precise design and manufacturing, ensuring stable energy transmission and durable equipment operation in harsh industrial environments.
Product Properties and Core Features
Superior Conductivity
The copper exhibits a conductivity ≥98% IACS (International Standard for Annealed Copper) and a resistivity as low as 0.0172 Ω·mm²/m, ensuring efficient current transmission in relay contacts, switch surfaces, and other applications, reducing energy loss and heat generation risks for Copper Stamp.
Combination of Mechanical Strength and Ductility
With a tensile strength of 220-260 MPa and an elongation ≥30%, it can withstand the mechanical impact of frequent switching operations and can be processed through deep drawing, bending, and other complex forming processes to meet diverse structural design requirements for Copper Stamping.
Excellent Corrosion Resistance and Thermal Stability
A dense oxide film naturally forms on the surface, maintaining long-term stability even in harsh environments such as humidity and salt spray; a melting point as high as 1083℃ makes it suitable for high-temperature applications such as fuses for Stamping Copper Sheet.
Performance Advantages
Low Contact Resistance Design
Through surface polishing (Ra≤0.8μm) and optimized plating (tin plating or silver plating optional), contact resistance is reduced to below 0.5mΩ, significantly improving the conductivity reliability of switch contacts and relay contacts for Custom Copper Stamping.
Arrow Erosion Resistance
The copper substrate forms a molten protective layer under the high temperature of an electric arc, effectively inhibiting contact ablation and extending product life to over 100,000 cycles (depending on specific operating conditions) for
Stamping Copper Sheet.
Vibration and Shock Resistance
Through structural reinforcement design (such as thickened edges and rib reinforcement), it can withstand vibration frequencies of 5-50Hz and impact accelerations of 10g, making it suitable for harsh environments such as rail transportation and industrial equipment for Copper Stamping.
Application Advantages
Relay Stamping Parts
Optimized elastic structure and fatigue life for rapid operation; optimized electromagnetic compatibility performance considering coil magnetic field effects; high-performance miniaturized design to address space constraints for Copper Stamp.
Switch and Contactor Stamping Parts
