Uniform Coating, Reliable Protection
Electroless nickel plating deposits a precise layer of nickel-phosphorous alloy onto metal parts without using electricity. This chemical process ensures a consistent coating thickness, even on complex shapes with sharp edges, threads, and deep recesses. In some cases, this uniformity eliminates the need for grinding after plating.
Key Benefits of Electroless Nickel
- Consistent Thickness: Expect an even coating across the entire part, unlike traditional plating methods.
- Excellent Corrosion Resistance: Provides robust protection against environmental factors.
- Enhanced Wear Resistance: Increases the lifespan of components exposed to friction.
- Solderability: Certain alloys offer good soldering properties for electronic applications.
- Potential Stainless Steel Replacement: In specific scenarios, it can be a cost-effective alternative.
- Lubricity: Offers similar friction-reducing properties to chromium plating.
Tailored Alloys for Specific Needs
We offer different nickel-phosphorous alloys to meet your specific performance requirements:
- High Phosphorus (10-13%): Choose this for maximum defense against corrosion, especially in acidic environments. It can achieve high hardness with heat treatment.
- Medium Phosphorus (5-9%): Ideal when appearance matters, offering a bright finish with a mix of structural properties.
- Low Phosphorus (<5%): Select this for the highest as-plated hardness, good resistance to alkaline environments, and excellent solderability.
Considerations for Optimal Results
The electroless nickel process is water-based and operates at around 200°F. While it coats evenly, proper solution flow is crucial. Complex geometries might require careful fixturing to ensure complete coverage. For certain materials like stainless steel and some non-ferrous metals, a post-plating heat treatment might be necessary to improve adhesion. Keep in mind that high-phosphorous nickel can sometimes change color after heat treatment for maximum hardness.
