High Phosphorus
Roughly 10 to 13 percent phosphorus. The most corrosion resistant option and essentially nonmagnetic, chosen for parts exposed to moisture, salt and chemicals.
When a component has bores, fine threads, deep pockets or close-fitting surfaces, coating uniformity can matter as much as corrosion and wear resistance. Electroless nickel deposits a nickel-phosphorus alloy through a controlled chemical bath, allowing the coating to build evenly on surfaces reached by the solution. Decorative Metal Coatings evaluates the part's material, dimensions and working conditions before recommending a suitable process.
Match the nickel-phosphorus deposit to the job it must do.
Electroless nickel is different from conventional electrolytic nickel because it uses a chemical reaction rather than electric current to deposit the coating. This makes it especially useful for parts with complicated geometry, where threads, bores and recessed areas need coverage alongside the outside surfaces. The resulting layer follows the part's shape and adds thickness consistently wherever the solution reaches.
Coating chemistry is selected according to performance needs, not just appearance. High phosphorus is commonly chosen when corrosion resistance is the priority. Low phosphorus offers greater hardness and wear resistance in the as-plated condition, while medium phosphorus is a balanced general-purpose option. A PTFE composite can provide a dry-lubricating, lower-friction surface, and a post-plate heat treatment may be considered when the application requires it.
The base metal determines the preparation sequence. Carbon and alloy steel, stainless steel, aluminum, copper, brass and bronze are identified on the service page, but they do not all enter the plating bath the same way. Provide the material and alloy, quantity, drawing or photos, coating thickness, finished dimensions and any masking requirements so the team can assess the part before quoting.
Send us the drawing or a few photos, the material, and what the part does in service. If your print calls out a coating specification or a finished dimension, include it. We will recommend a phosphorus range and a thickness, tell you whether masking or heat treatment makes sense, and send back a written quote.
Available services include low-, medium- and high-phosphorus electroless nickel, PTFE composite deposits, bright and satin appearances, masking, stripping and replating, controlled coating thickness and post-plate heat treatment. The specification is selected around the part's alloy, fit, wear exposure and corrosion environment.
Roughly 10 to 13 percent phosphorus. The most corrosion resistant option and essentially nonmagnetic, chosen for parts exposed to moisture, salt and chemicals.
Roughly 5 to 9 percent phosphorus. The general purpose workhorse, with a bright appearance and a balance of hardness, wear and corrosion protection that suits most industrial parts.
Roughly 1 to 5 percent phosphorus. The hardest deposit as plated, selected for sliding surfaces, tooling and components where wear resistance matters more than chemical exposure.
A bake after plating can raise hardness to a level that competes with hard chrome, or relieve hydrogen in high strength steel. The cycle is matched to the chemistry and the base metal.
Fine PTFE particles locked into the nickel matrix create a dry lubricating surface. Used on molds, fasteners, sliding mechanisms and anything that needs low friction or easy release.
Internal passages, blind holes, fine threads and deep pockets get the same coating as the outside of the part. Often the only practical choice when conventional plating cannot reach.
We run all three of these processes in house, so we have no reason to push one over another. Here is how they differ and when each one is the right call.
The plating bath is the same for every part. The preparation is not. Each substrate has its own cleaning and activation sequence, and getting it right is what keeps the coating attached.
The most common substrate we coat. After degreasing and acid activation, steel accepts every phosphorus range. High strength steels can receive a hydrogen relief bake after plating.
Its passive oxide film blocks adhesion, so it gets a nickel strike before the electroless bath. Often coated to stop galling on threads or to add surface hardness.
Aluminum oxidizes within seconds, so it receives a zincate treatment that protects the surface until the nickel takes over. The alloy matters, so tell us the grade if you know it.
Copper does not start the reaction on its own, so it is activated before plating. Electroless nickel then acts as a durable barrier against tarnish and diffusion.
Valve bodies, fittings and marine components plate cleanly once activated. The nickel layer protects against dezincification and adds a harder working surface.
Nickel alloys, tool steels and cast parts can be coated case by case. Send the exact alloy designation so we can confirm the activation sequence before you ship.
Everything we offer around electroless nickel, from the chemistry itself to masking, stripping and post plate treatment.
To start, provide the component drawing or clear photos, identify the substrate and alloy, and explain what the part does in service. Include any print specification, required thickness, finished dimension, quantity and areas to mask. The team can then recommend a phosphorus range and thickness, discuss heat treatment if relevant, and prepare a written quote before the parts are shipped.
Send photos or a drawing, the material, the quantity and any coating callout on your print.
We suggest a phosphorus range and thickness and send a written quote within 24 business hours.
Once the quote is approved, use the assigned quote number and follow the shop's receiving instructions. Bag or wrap each component separately, cap threads and ports when practical, keep parts from rubbing together and add enough padding to protect machined and sealing surfaces. Put a parts list and the quote number inside the package.
Parts are degreased, masked where needed, activated for their alloy and plated in a controlled bath.
Coverage and thickness are checked, any heat treatment is completed, and parts ship back insured.
From custom builders to industrial manufacturers, our clients trust us to deliver the same result every time.
For projects in the Akron area, possible applications include production machinery, tooling, fluid-handling components and precision-fabricated parts. A component's location does not establish its suitability: the base alloy, dimensions, surface condition and operating environment must be reviewed before a coating recommendation is made.
CNC parts with tight tolerances, where the coating has to go on evenly so the part still fits after plating.
Valves, pump housings, shafts and fixtures that need corrosion protection inside passages as well as outside.
Brackets, fuel system fittings, brake parts and engine components protected from heat, fluids and road salt.
Fittings, pump parts and deck components where high phosphorus nickel stands up to constant salt exposure.
Plastic injection molds, dies and fixtures that need a hard surface, clean release and protection from corrosion.
Threaded parts, hinges and fittings coated all the way into the threads for smooth assembly and lasting protection.
Drag the handle on any photo to compare the part as it arrived with the finished electroless nickel surface.
Before
Arrived with surface rust and a failed zinc finish. Stripped, cleaned and activated, then coated with medium phosphorus nickel for an even, corrosion resistant surface that kept the part within its fit.
Before
Dull, oxidized housings with threaded ports. Each piece went through a zincate pretreatment and received high phosphorus nickel that reached every port and internal face.
Before
Deep pockets and cross drilled passages that conventional plating could not reach evenly. Electroless nickel coated the inside and the outside at the same thickness.
Big order or a single knob, same care.
Homeowners send us one faucet. Companies in and out of state send production runs of hundreds or thousands of parts. Both get a written quote and the same inspection before anything ships back.
Functional plating only counts if the part works when it goes back into the assembly. That is the standard we inspect to on every order.
Bath chemistry, temperature and nickel content are monitored throughout the run so the deposit stays consistent from the first part to the last.
Steel, stainless and aluminum each follow their own cleaning and activation sequence, which is what keeps the coating bonded.
Coverage and coating thickness are checked against your requirement before parts are released for packing.
Finished parts are separated and packed so threads, sealing faces and machined surfaces arrive exactly as they left the tank.
Since 1989 we have plated parts for machine shops, manufacturers, restorers and builders. Decorative work and functional coatings run under the same roof, with the same inspection standard.

Protect critical surfaces from installation through service.
Electroless nickel is a functional coating, so care should reflect the component's application and the environment where it operates. Use cleaning agents and maintenance procedures approved for the equipment. Do not assume that abrasive compounds, metal polishes or aggressive chemicals are compatible with the coating or the assembled part.
Avoid scraping or striking coated threads, sealing faces and precision fits during storage and installation. The selected coating thickness contributes to the finished dimensions, including inside diameters and threaded features. Where a fit is critical, confirm dimensions and masking requirements before the parts enter production.
Thickness is the other key number. Electroless nickel builds evenly, so the coating adds the same amount to every surface, inside diameters included. On a precision fit, that growth has to be planned for. Let us know the finished dimension you need, and whether any threads, bores or sealing faces should be masked and left bare.
Finally, mention quantity and timing. A single prototype and a recurring production run are scheduled differently, and knowing what is coming next lets us hold the same settings from batch to batch.

Frequently Asked Questions
These answers explain how the coating works, what information helps with a quote and how dimensional requirements are handled.
It can coat surfaces reached by the plating solution, including bores, blind holes, internal passages and threads. This uniformity is one of the main reasons to consider electroless nickel for complex components. Areas that must remain bare can be discussed for masking.
No. High phosphorus is selected when corrosion resistance and nonmagnetic behavior are important. Low phosphorus is harder as plated and may suit wear-focused parts, while medium phosphorus balances several general-purpose needs. The service conditions should determine the choice.
Include the base metal and alloy if known, photos or a drawing, quantity, required coating thickness, finished dimensions, any specification on the print and areas that need masking. Also explain whether corrosion, wear or friction is the main concern.
These metals are listed as compatible substrates on the service page. Copper requires activation before plating, while brass and bronze also need an appropriate activation step. The exact part and its condition should be reviewed before the process is confirmed.
