Product Introduction
In electric vehicle power protection systems, fuse components must withstand high electrical loads, thermal stress, and long-term environmental exposure. Our Tin Plating Copper End Caps For Fuses are precision-manufactured components specifically developed for automotive and new energy fuse applications, combining excellent mechanical strength, stable electrical performance, and reliable solderability.
These products are widely used as End caps and Contact Welding Components in EV fuses, charging systems, battery protection units, and power distribution assemblies, ensuring secure electrical connections and consistent performance throughout the service life of the vehicle.
Material & Mechanical Properties
The core material of our fuse caps and contacts is high-quality copper alloy, selected for its outstanding conductivity and mechanical reliability.
Mechanical Properties of Tin Plating Copper End Caps for Fuse
Density: 8.9 g/cm³
Copper strip condition: M / Y4 / Y2 / Y / T
Strip thickness: ≥ 0.2 mm
Tensile strength (Rm): ≥ 195–350 MPa
Elongation after fracture: ≥ 3–30%
Hardness: HV 60–120
These parameters ensure the End Cap and Terminal maintain dimensional stability and mechanical integrity during welding, assembly, and long-term operation under vibration and thermal cycling typical of electric vehicles.
Matte Tin Plating Advantage & Specifications
Surface Appearance
The surface layer of our Matte Tin Fuse Terminals has a foggy finish with relatively rough crystals. While this finish is prone to fingerprint marks, it enhances the welding compatibility for End Cap and Terminal applications.
Plating Thickness
Available in 5um or 8um (customizable based on specific application requirements), ensuring flexibility for different fuse types.
Superior Performance
Matte Tin Fuse Terminal Contacts offer better solderability and tin resistance compared to bright tin alternatives, making them ideal for critical welding applications in Copper Cap Contact for Vehicle Fuse and Copper Cap Contact for Electric Vehicle Fuse.
Application Guidance
Matte Tin Automotive Fuse Terminal is recommended for single-use workpieces, while Bright Tin Fuse Terminal Contact is suitable for solder-required workpieces that are also appearance parts.
Welding Compatibility & Structural Design
Our products are engineered to support stable and repeatable welding performance, whether used in laser welding, resistance welding, or brazing processes.
Optimized geometry for End Cap and Terminal welding
Uniform tin layer thickness to ensure consistent electrical contact
High bonding strength at welding interfaces
Suitable for both automated and semi-automated production lines
These advantages make the components ideal as Outer Cap and Terminal solutions in demanding EV fuse assemblies.
