Products Description

Our Silver Plated Copper Stamping Parts combine the electrical conductivity of high-purity copper with the surface durability of silver plating. Commonly used as Copper Stamped Electrical Contacts in relays, switches, fuses, and circuit breakers, these components are optimized for stable current transmission and long-term reliability.

Each part is manufactured using high-speed copper pressing and stamping processes, followed by electroplating silver on copper to reduce contact resistance and enhance corrosion protection.

We serve a wide range of industries, including automotive, industrial controls, smart grid components, and HVDC systems, offering custom tooling, precision forming, and post-processing.

Key Features

Superior Electrical Conductivity

Copper is renowned for its exceptional electrical conductivity, and our Electroplating Silver on Copper parts fully utilizes this property to ensure efficient current transfer. This makes them ideal for use in electrical systems where minimal resistance and optimal performance are crucial.

Enhanced Durability and Corrosion Resistance

The silver plating applied to our copper parts provides an additional layer of protection against wear and corrosion. This ensures that the Copper Stamped Electrical Contacts maintain their performance and integrity over time, even in demanding operating conditions.

High - Precision Stamping

Utilizing advanced stamping technology, we produce Copper with Silver Plating parts with high precision and consistency. The dimensions and shape of each part are controlled within tight tolerances, ensuring a perfect fit with other components in your electrical system.

Copper Stamping Parts Characteristics

Material & Plating Mastery

Conductivity benchmark

Using T2 copper (copper content ≥99.9%), the conductivity reaches 100% IACS, ensuring extremely low resistance loss (60% lower than brass), suitable for high current transmission scenarios (such as 100A + fuse contacts, high-voltage contactor conductive bridge).

Ductility and stability

Soft hardness HV 60-80, elongation ≥30%, supports deep drawing, precision bending, and other complex-forming (such as 0.3mm ultra-thin contact or R0.5mm small radius bending), stable performance in the temperature range of -40℃~+150℃.

Enhanced conductivity

5-10μm pure silver coating (purity ≥ 99.9%), contact resistance reduced by 35%, oxidation start temperature increased to 200℃, effectively cope with sulfur-containing/high humidity environments (such as outdoor distribution cabinets, marine equipment relays).

Wear resistance and life optimization

Silver coating hardness HV 110-130, no coating shedding after 1000 plug-in tests, suitable for high-frequency signal relays (operation frequency ≥ 10 times/second).

Relays and contactors

Contacts/contact bridges: Silver-plated copper parts ensure low contact resistance, reduce arc erosion and extend equipment life (suitable for 12V low-voltage relays to 1000V high-voltage DC contactors).
Armature bracket: Copper stampings provide a stable conductive circuit, support millisecond-level response (action time ≤5ms), and are used in automotive BMS battery management systems.

Switches and sockets

Conductive sheets/pins: The silver-plated surface has a 3-fold improvement in anti-sulfurization performance, suitable for humid environments such as bathrooms and kitchens for Copper Pressed Stamped Parts (such as IP66 waterproof switches).
Micro switch contacts: 0.2mm ultra-thin molding technology to meet miniaturization requirements (such as smart home appliance micro switches).

Fuse and terminals

Fuse connector: High-purity copper substrate ensures uniform heat conduction during melting, in line with IEC 60269 fast-blow standards.
High-voltage terminals: The Copper Pressed Stamped Parts reduce the risk of oxidation and are suitable for DC terminals of energy storage equipment (600V/500A high voltage and high current scenarios).
