Balanced Performance for Diverse Needs

Metal Finishing Group provides Electroless Nickel Mid-Phos plating services, applying a uniform, autocatalytic nickel-phosphorus alloy coating to a wide array of substrates. This process differs from electrolytic plating because it does not require an external electrical current, ensuring a consistent and even deposit even on complex geometries. Mid-phosphorus electroless nickel offers a balanced combination of hardness, corrosion resistance, and ductility.

Electroless Nickel Mid-Phos is chosen when components require excellent wear resistance, reliable corrosion protection, and a uniform coating thickness across all surfaces. It is ideal for parts with intricate shapes, internal diameters, or blind holes where traditional electroplating would not be effective. This versatile finish provides a consistent, high-performance layer crucial for demanding industrial, automotive, and general engineering applications.

Our Electroless Nickel Mid-Phos Capabilities: Uniformity and Versatility

We offer precise Electroless Nickel Mid-Phos plating services, ensuring a uniform and high-quality deposit for your components.

  • Autocatalytic Deposition: Ensures an even coating thickness over all surfaces, regardless of part geometry, edges, or recesses.
  • Phosphorus Content: Achieves a phosphorus content typically ranging from 5% to 9% by weight, providing a balance of hardness and corrosion resistance.
  • As-Plated Hardness: Delivers good as-plated hardness, which can be further increased with post-plate heat treatment.
  • Corrosion Resistance: Provides excellent corrosion protection, forming a robust barrier against various corrosive environments.
  • Wear Resistance: Enhances the surface’s resistance to abrasion and wear, extending component lifespan.
  • Lubricity: Offers inherent lubricity, reducing friction and galling in moving parts.
  • Diverse Substrate Compatibility: Can be applied to steel, stainless steel, aluminum, copper, brass, and other alloys.
  • Precision Thickness Control: We achieve exacting plating thicknesses to meet specific design and performance requirements.
  • In-house Quality Verification: We conduct adhesion, thickness, and hardness testing to ensure coating integrity and compliance.

Properties of Electroless Nickel Mid-Phos:

Electroless Nickel Mid-Phos imparts several key properties that enhance the performance and longevity of components:

  • Uniform Coating Thickness: Ensures consistent coverage even on complex shapes, eliminating issues common with electroplating.
  • Balanced Hardness and Ductility: Provides a good combination of hardness for wear resistance and enough ductility to prevent cracking under stress.
  • Excellent Corrosion Resistance: Forms a reliable barrier against a wide range of corrosive media.
  • High Wear and Abrasion Resistance: Protects surfaces from friction and abrasive forces.
  • Reduced Friction: Offers good lubricity, which can minimize galling and improve the performance of mating parts.
  • Magnetic Properties: The coating is generally magnetic in its as-plated condition.
  • Bright to Semi-Bright Finish: Provides an attractive appearance, ranging from semi-bright to bright depending on bath chemistry.

Applicable Specifications We Adhere To:

Our Electroless Nickel Mid-Phos processes consistently meet or exceed crucial industry standards, ensuring the quality and performance of your components. We regularly process to:

  • ASTM B733 (Standard Specification for Autocatalytic (Electroless) Nickel-Phosphorus Coatings on Metals)
  • MIL-C-26074 (largely superseded by ASTM B733, but often referenced)
  • AMS 2404 (Electroless Nickel Plating)
  • And various customer-specific requirements.

Typical Electroless Nickel Mid-Phos Applications:

Electroless Nickel Mid-Phos is widely applied across numerous industries for its balanced functional benefits:

  • Automotive Industry: Used for fuel system components, brake parts, gears, and shafts for wear and corrosion resistance.
  • Industrial Machinery: Applied to pumps, valves, molds, and tooling for enhanced durability and lubricity.
  • Electronics: Protects connectors, housings, and heat sinks, providing both corrosion resistance and conductivity.
  • Oil & Gas: Used for downhole tools and pipeline components requiring corrosion and wear protection in harsh environments.
  • Aerospace: Applied to various components where uniform coating thickness and resistance to wear are critical.
  • Textile Industry: Enhances the wear life of rollers, guides, and other machinery parts.
  • Food Processing Equipment: Provides a corrosion-resistant and easy-to-clean surface.
