Custom Nickel Silver EMI RFI Shielding Parts

Nickel silver, also known as German silver or NS alloy, is a non-magnetic metal composed primarily of copper, nickel, and zinc. It is widely favored for EMI/RFI shielding applications due to its unique balance of electrical, mechanical, and corrosion-resistant properties.

Key Benefits of Nickel Silver Shields:

1. Excellent Shielding Effectiveness:
   Nickel silver provides strong attenuation of both electric and magnetic fields, making it ideal for shielding high-frequency signals in compact electronic assemblies.

2. Corrosion Resistance:
   The presence of nickel enhances the metal’s resistance to oxidation and environmental degradation, ensuring long-term durability in various operating environments.

3. Non-Magnetic Properties:
   Because it is non-ferromagnetic, nickel silver does not interfere with magnetic components, which is critical for shielding sensitive electronic systems.

4. Solderability and Workability:
   Nickel silver is easy to form, stamp, and solder, allowing for precise fabrication and reliable integration into PCB assemblies.

5. Aesthetic Appearance:
   With its clean, silver-like surface finish, nickel silver provides a professional appearance and does not require additional plating for most indoor applications.

Our Manufacturing Capabilities

At TMN Metal Parts Fabrication Factory, we use advanced fabrication technologies and high-precision tooling to produce nickel silver shielding parts in a variety of shapes and sizes. Our production process is designed for efficiency, repeatability, and customization.

Capabilities include:

• Progressive stamping and deep drawing

• CNC machining and laser cutting (for prototypes or low volumes)

• In-house tool and die development for complex part geometries

• High-speed production for large volume orders

• Spot welding and assembly of multi-part shields

• Surface treatment and optional plating (tin, nickel, etc.)

• Shield design consulting and engineering support

Our skilled engineering team works closely with each client to develop shielding components that fit their unique PCB layouts and performance requirements. Whether you need a simple one-piece can or a complex multi-cavity shielding cage, we deliver with accuracy and consistency.

Types of Nickel Silver Shields We Manufacture

We offer a comprehensive range of standard and custom EMI/RFI shielding components using nickel silver. These include:

1. One-Piece Shield Cans

These are single-piece metal enclosures that cover sensitive circuit areas. They can be attached via soldering or through press-fit pins. One-piece cans are cost-effective and easy to install for high-volume applications.

2. Two-Piece Shields (Cover and Frame)

A two-piece shield includes a base frame that is soldered to the PCB and a removable cover. This design allows easy rework or testing of components during prototyping, assembly, or repair. It is particularly popular in RF and wireless module applications.

3. Multi-Cavity Shields

For densely populated PCBs with multiple noise-sensitive zones, we produce multi-cavity shields that isolate several areas within one integrated component. These are ideal for advanced communication and signal processing devices.

4. Custom Shields

Our factory specializes in custom shielding designs to meet non-standard form factors or unique shielding challenges. We can accommodate irregular PCB layouts, heat dissipation requirements, and grounding needs.
