Product Introduction
In electric vehicles and new energy power systems, fuse components must withstand high electrical loads, frequent thermal cycling, and harsh operating environments. This Caps For Fuse Holders is a precision-manufactured component designed for ceramic bolted fuse assemblies, providing reliable mechanical fixation and stable electrical performance in critical protection circuits.
Manufactured from high-quality H85 brass, this product combines excellent electrical conductivity, thermal conductivity, corrosion resistance, and outstanding formability. It is widely applied in fast-acting protection for overload and short-circuit conditions in EV capacitors, charging piles, battery circuits, and DC power systems.
Material Characteristics – H85 Brass
This product is manufactured using H85 brass, a copper-zinc alloy recognized for its balanced mechanical and electrical properties:
High electrical and thermal conductivity, suitable for current-carrying fuse components
Excellent corrosion resistance in atmospheric and freshwater environments
Superior plasticity, enabling complex cold and hot forming processes
Good weldability and forgeability, ensuring structural integrity during assembly
As a result, this brass end cap maintains stable performance even under continuous electrical stress and elevated operating temperatures common in new energy applications.
Nickel Plating Surface Treatment
To further enhance durability and electrical reliability, the outer cap undergoes a controlled nickel-plating process. Nickel plating is commonly used as a protective and functional coating in power electronics components.
Nickel Plating Process (10 Steps)
Electroplating pretreatment
Cleaning
Pickling
Surface activation
Nickel plating
Post-plating cleaning
Neutralization
Secondary cleaning
Dehydration
Final inspection
This process significantly improves corrosion resistance, surface hardness, and wear resistance, ensuring consistent performance over long service cycles. In demanding environments, the plated surface also enhances contact stability during repeated thermal expansion and contraction.
Product Range and Customization Options
In addition to H85 brass outer caps, we offer a comprehensive portfolio of fuse terminals and caps made from various materials, including:
T2 copper
H65 brass
H59 brass
Zinc-based aluminum alloy
Available product forms include:
Inner caps and outer caps
One-piece bolted caps
L-type terminals
Blade-shaped terminals
Sockets and clips
These products are widely used in EV, PV, and industrial fusible systems. Depending on the application context, this component may also function similarly to a brass pipe end cap or brass plumbing cap, offering both mechanical closure and conductive performance.
