Manganese Phosphate Plating

Manganese Phosphate Plating

This process involves plating ferrous metals with manganese phosphate by immersion. The resulting coating has many benefits:

  • Reduces friction and wear on moving parts
  • Corrosion Resistance

Manganese Phosphate Plating Capabilities

Type of Plating
Manganese Phosphate Plating
Improves life of component or product by reducing coefficient of friction and wear between moving parts. Also provides corrosion resistance.
Process Approvals
For Manganese Phosphate Plating we adhere to:
  • MIL-DTL-16232 Type M (Replaces DOD-P-16232): Phosphate Coating, Heavy, Manganese or Zinc Base
MIL-DTL-16232 Type M (Replaces DOD-P-16232)MIL-DTL-16232 Type M (Replaces DOD-P-16232) (PDF - 63KB)
Manganese Phosphate
Base Materials Worked
This specification focuses on manganese phosphate plating of all ferrous metals (Iron and Steel).
Plating Type
Type M = Manganese Phosphate Base
Plating Class
The Manganese Phosphate plating should be of the following classes:
  • Class 1 = Supplementary preservative treatment or coating, as specified
  • Class 2 = Supplementary treatment with lubricating oil conforming MIL-PRF-16173, Grade 3 or MIL-PRF-3150
  • Class 3 = No supplementary treatment
  • Class 4 = Chemically converted (may be dyed to color as specified) With no supplementary coating or coating as specified
All manganese phosphate plating processes are performed manually to ensure the proper care is given to each step.
Additional Operations
We offer several additional operations that may be required for your product: Cleaning, Magnetic Particle Inspection (NDT), Penetrant Inspection (NDT), Hardness & Conductivity Testing (NDT), Dry Film/Solid Film Lubricants and Primer & Topcoat Painting.
Please let us know if you require any of these additional services.
Quality Control
All plating processes are subject to our rigorous Quality Assurance process. All work is reviewed and inspected to be in compliance with the specification (Process Approval requested).
Industries Served
We are committed to providing the aerospace and defense industries with the highest quality metal finishing, testing, and painting available.
Environmental Responsibility
As a corporate citizen, we are committed to responsibly protecting our environment. We have a state-of-the-art $2 Million Waste Prevention System in place. All hazardous waste materials are 100% recycled and rendered harmless.

We know that this is important to you, and so we maintain an open door policy concerning environmental inspections of our facility.
With over 50 years in the metal finishing industry, we have the expertise you can depend on.
Minimum Order
We can provide manganese phosphate plating for prototype to high volume runs.
