Triple-Layer Protection, Bright Silver Finish, High Surface Hardness
We supply Custom Neodymium Magnets finished with the industry-standard Ni-Cu-Ni (Nickel-Copper-Nickel) plating.
This is the most popular surface treatment for general-purpose magnets.
It offers the best balance of Durability, Cost, and Aesthetics.
Nickel plating is recognizable by its bright, mirror-like silver finish,
And it is ideal for consumer electronics, luxury packaging, and clean-room environments.
For these applications, the magnet must look premium and remain dust-free.
Not Just “Nickel”
Many buyers assume “Nickel Plating” is a single dip.
Ours is a structural shield.
1. The “Triple-Layer” Difference:
The Risk:
Cheap magnets use a single layer of Nickel.
This is porous and allows moisture to reach the iron core.
And it may cause the magnet to rust from the inside out.
Our Standard: We use a strictly controlled Ni-Cu-Ni stack:
1). Base Nickel: Bonds to the magnet.
2). Copper (Critical): A soft middle layer that seals micro-pores and provides humidity resistance.
3). Top Nickel: A hard outer shell for scratch resistance and shine.
2. Surface Hardness (Wear Resistance):
The Benefit:
Nickel is a hard metal.
Unlike Epoxy or Zinc (which are softer), Nickel plating withstands the impact of magnets “snapping” together.
The Application:
Perfect for Magnetic Latches and Closures.
Their wwo magnets will repeatedly hit each other.
Nickel resists chipping better than other coatings.
3. Cleanliness:
The Benefit:
Nickel does not crumble or shed particles (unlike unplated ferrite).
It is suitable for medical offices, labs, and food-safe packaging.
They do not allow dust contamination.
Adhesion & Environment
Nickel is great for many things, but not everything.
1. The “Slippery” Factor (Gluing):
The Problem:
The mirror finish of Nickel is very smooth and has low surface energy.
Standard glues often peel off.
The Advice:
If you are gluing this magnet, you must use a high-performance adhesive (like 3M VHB or Loctite Acrylics).
For maximum bond strength, we recommend cleaning the surface with alcohol to remove manufacturing oils before gluing.
2. The Saltwater Limit:
The Warning:
Nickel slows down rust, but it is not waterproof.
If exposed to constant saltwater (marine) or outdoor rain, Nickel will eventually pit and corrode.
The Alternative:
For wet environments, please upgrade to our Epoxy or Parylene coated magnets.
Ideal Applications
Luxury Packaging: Invisible closures for rigid boxes (the clean silver look implies quality).
Consumer Electronics: Magnets used in cases, stands, and charging docks.
Holding Assemblies: Magnetic hooks and office magnets.
Sensors: Indoor automation triggers.
Ordering Guide: Cosmetic Standards
Since Nickel is often a visible part, we need to know your aesthetic requirements:
1). Dimensions: Length x Width x Thickness (or Diameter).
2). Cosmetic Grade:
– Industrial Grade: (Minor surface scratches allowed; functionality is key).
– Cosmetic Grade: (For visible consumer parts—Face A must be scratch-free).
3). Grade: N35, N42, N52?
4). Application: “Will this be glued?”
– If yes, we can advise on cleaning protocols.
