| Parameter | Specification | Importance to Large Companies |
|---|---|---|
| Material Composition | copper | Ensures high conductivity, durability, and resistance to arc erosion for industrial applications. |
| Contact Resistance | ≤ 0.2 mΩ (milliohms) | Minimizes energy loss and heat generation, critical for high-efficiency systems. |
| Hardness | 80-150 HV (Vickers Hardness) | Provides mechanical strength and wear resistance for long-term reliability. |
| Operating Temperature | -50°C to +200°C | Suitable for extreme environments, including automotive, aerospace, and industrial applications. |
| Electrical Life | ≥ 500,000 cycles | Ensures longevity and reliability in high-frequency switching applications. |
| Arc Resistance | High resistance to arc erosion (tested at 10A-100A) | Prevents failure in high-current applications like circuit breakers and relays. |
| Corrosion Resistance | Excellent resistance to oxidation, sulfidation, and tarnishing | Essential for harsh environments, such as marine and outdoor applications. |
| Surface Finish | Polished or coated (e.g., gold plating, rhodium plating) | Enhances conductivity, reduces wear, and prevents oxidation. |
| Compliance Standards | RoHS, REACH, UL, IEC 60664, ISO 9001 | Meets international regulatory, safety, and quality standards for global supply chains. |
| Dimensions | Customizable (e.g., diameter: 1mm-25mm, thickness: 0.3mm-6mm) | Adaptable to specific application requirements in various industries. |
| Load Capacity | 0.5A to 500A+ | Supports a wide range of applications, from low-power electronics to heavy industrial systems. |
| Packaging | Anti-tarnish packaging (vacuum-sealed or nitrogen-filled) | Protects silver contacts from oxidation during storage and shipping. |
| Testing & Certification | Third-party tested for electrical performance, durability, and environmental resistance | Ensures consistent quality and reliability for large-scale procurement. |
| Lead Time | 2-4 weeks (depending on customization and quantity) | Ensures timely delivery for large-scale production needs. |
