Product Introduction
Products Description
Our range of Fuse Terminal solutions, centered on Fuse Link Contact technology, includes specialized options like, End Tag Copper, and Copper Electrical Fuse Contacts-all engineered to meet the rigorous demands of modern electrical systems.
Crafted from high-purity copper materials, these components address key pain points in traditional fuse contacts, such as poor conductivity, easy oxidation, and short service life. Whether for industrial power distribution, automotive electrical systems, or household appliances, our products ensure stable current flow, fast overload response, and long-term durability. As global electrical safety standards (such as IEC 60269 and UL 248) become increasingly strict, our Fuse End Tag solutions provide manufacturers with a reliable path to compliance, helping them enhance the safety and market competitiveness of end products.
Product Features
Superior Conductivity
All our copper-based fuse contacts use 99.95% high-purity electrolytic copper, which has an electrical conductivity of ≥58 MS/m-far higher than brass (47 MS/m) or aluminum (37 MS/m) alternatives. This ensures minimal voltage drop (≤0.1V at rated current) and reduces energy loss during operation.
01
Exceptional Corrosion Resistance
Through surface treatments like tin plating, silver plating, or anti-tarnish coating, our components resist oxidation, sulfurization, and salt spray. Fuse Link Contact Copper with silver plating, for example, maintains stable Fuse Terminal resistance even after 1,000 hours of exposure to industrial exhaust environments.
02
High Mechanical Strength
The one-piece stamping and annealing process enhances the copper material's tensile strength (≥220MPa) and yield strength (≥110MPa). End Tag Copper can withstand a pulling force of 50N without deformation, ensuring it remains securely connected to fuse bodies during transportation and installation.
03
Precision Dimensional Control
Advanced manufacturing technologies-including CNC stamping (tolerance ±0.02mm) and laser cutting (tolerance ±0.01mm)-ensure consistent component dimensions. This reduces assembly errors, as Copper Sheet Fuse Parts can be seamlessly integrated into automated fuse production lines without manual adjustment.
04
Wide Temperature Adaptability
The copper material's inherent thermal stability, combined with heat-dissipating designs (such as micro-channels in Copper Electrical Fuse Contacts), allows our products to operate reliably in extreme temperatures. They maintain performance from -40°C (cold start in automotive applications) to 120°C (high-temperature industrial environments).
05
Production Process
1. Raw Material Selection & Inspection: We source 99.95% high-purity electrolytic copper coils from certified suppliers (e.g., Chilean Copper Corporation). Each batch undergoes spectroscopic analysis to verify purity and detect impurities (≤0.05%), ensuring compliance with material standards.
2. Precision Stamping/Laser Cutting: For components like End Tag Copper and Fuse Link Contact Copper, we use 200-ton CNC stamping machines to form the desired shape-with real-time monitoring of pressure (150–180kN) and temperature (≤50°C) to avoid material deformation. For miniaturized Copper Sheet Fuse Parts, we employ fiber laser cutting machines (precision ±0.01mm) to achieve complex patterns.
3. Annealing Treatment: Stamped or cut components are annealed in a nitrogen-protected furnace at 350–400°C for 1–2 hours. This process relieves internal stress, improves ductility (increasing elongation by 15%), and enhances conductivity.
4. Surface Treatment: Components undergo surface plating or coating based on application needs. Silver plating (for high-conductivity requirements) uses an electrolytic process with a thickness of 1–2μm, while tin plating (for cost-effective corrosion resistance) is applied via hot-dip plating (3–5μm). Copper Sheet Fuse Parts receive an anti-tarnish coating (silane-based) to prevent oxidation.
5. Quality Inspection: Each component undergoes 100% inspection, including:
Dimensional check (using coordinate measuring machines, tolerance ±0.02mm);
Conductivity test (using a four-point probe, ensuring ≥58 MS/m);
Corrosion resistance test (salt spray test for 480 hours, no oxidation);
Contact resistance test (using a micro-ohmmeter, ≤5mΩ).
6. Packaging & Storage: Qualified components are packaged in anti-static bags (to prevent electrostatic damage) and placed in moisture-proof cartons. Each package is labeled with batch numbers, production dates, and quality certificates for traceability.
Application Scenarios
Our Fuse Terminals are widely used across multiple industries, thanks to their versatility and performance:
Automotive Industry: Copper Electrical Fuse Contacts and End Blade Ferrules Copper are used in automotive fuse boxes (12V/24V systems) for cars, trucks, and electric vehicles (EVs). They protect critical electrical systems, such as engines, air conditioning, and EV battery management systems (BMS), from overloads and short circuits. We supply these components to leading automotive manufacturers, including Toyota and Volkswagen.
Industrial Power Distribution: End Blade Ferrules Copper is integrated into medium-voltage fuse links (600V–10kV) for industrial switchgear, transformers, and motor control centers. In a steel plant in China, our Fuse Terminals have been operating reliably for 3 years, with zero fuse-related downtime.
Household Appliances: End Tag Copper and Copper Sheet Fuse Parts are used in fuses for refrigerators, air conditioners, and washing machines (220V/110V systems). Their small size and high reliability make them ideal for miniaturized appliance designs, as adopted by LG and Samsung.
Renewable Energy Systems: Our products are used in fuses for solar inverters (DC 1,500V) and wind turbine control systems. Fuse Link Contact Copper with silver plating ensures stable performance in outdoor environments, resisting corrosion from rain, dust, and UV radiation. We supply these components to solar energy companies like JinkoSolar.
Consumer Electronics: Copper Sheet Fuse Parts are used in miniaturized fuses for smartphones, laptops, and power banks (5V–24V systems). Their thin gauge (0.1–0.5mm) and precision dimensions fit compact electronic designs, protecting devices from overcurrent damage.
