Products Description
Relay Copper Stamping Parts are high-conductivity copper stampings specifically designed for the T90 general-purpose relay reed terminal structure. The surface features a 3–5 μm tin plating layer to enhance oxidation resistance and solderability. These terminals perform critical current conduction and connection functions in electrical components such as relays, switches, contactors, and fuses, requiring low contact resistance, a stable soldering window, and long-term service reliability.
Core Product Nature and Characteristics
Copper Substrate
Copper Sheet Stamping for Electric Relay utilizes high-purity electrolytic copper strip, it possesses excellent electrical and thermal conductivity, effectively reducing the current-carrying temperature rise of the relay's stationary spring circuit.
Tin Plating Engineering Value
The 3–5 μm tin layer inhibits copper surface oxidation while forming a stable solder wetting interface, suitable for wave soldering and reflow soldering processes for Copper Stamping Electrical Precision Parts.
Mechanical Stability
Through cold work hardening and geometrically reinforced design, the Copper Stamped Components' resistance to deformation during insertion and assembly is ensured.
Structural Design and Precision Control
Alignment Accuracy
The alignment accuracy of the mold is extremely high, typically controlled to ≤0.01mm. This ensures that the centerlines of each batch of Metal Stamping Parts Electric Copper are perfectly aligned.
Blanking Clearance
Based on the copper strip thickness (typically 0.1-2.0mm), the blanking clearance is set within the range of 5%-8% of the material thickness to ensure a smooth blanking process for Copper Stamped Components.
Surface Finish
Through mirror EDM, the surface finish of the cavity can reach Ra≤0.4μm. This not only improves the appearance of the finished Copper Stamping Electrical Precision Parts but also reduces subsequent cleaning processes.
