Product Introduction
product description
The fuse copper cap is a critical component of the fuse assembly, and it is typically made from high-quality copper material due to its excellent electrical conductivity and thermal properties. The copper cap serves as the contact point for the fuse element inside the fuse holder or fuse link. When excessive current flows through the fuse, the element inside the copper cap will melt, breaking the circuit and disconnecting the power to the protected system.

surface treatment
- Cleaning: During manufacturing, copper caps undergo cleaning to eliminate dirt, grease, and impurities from the surface, ensuring cleanliness and smoothness.
- Oxygen Removal Treatment: Vital for preventing oxidation, this step removes the oxide layer from copper surfaces to halt further oxidation.
- Pickling: A common approach involving immersion in acidic solutions to eliminate oxides and surface contaminants, resulting in improved smoothness.
- Electroplating: Often applied to enhance corrosion resistance and aesthetics, electroplating deposits a protective and decorative metal layer like nickel, tin, or chromium onto the copper surface.
- Polishing: Ensures uniformity, smoothness, and the elimination of surface defects or irregularities.
- Spraying: Occasionally used for color variety and additional protection.
- Cleaning and Drying: After preparation, copper caps are cleaned once more to eliminate chemical residues, followed by drying for packaging and shipping readiness.
