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.
Electroless nickel plating deposits a nickel-phosphorus alloy through a controlled chemical reaction, not an electric current. The process can coat exposed faces, threads, bores and recessed features with a consistent layer, helping suitable components resist corrosion and wear while maintaining planned dimensions. Decorative Metal Coatings reviews the part, its base metal and its working conditions before recommending a coating approach.
Choose coating chemistry around how the part performs.
Unlike electrolytic plating, electroless nickel does not depend on electrical current to deposit metal. The chemical process can produce an even nickel-phosphorus layer on complex shapes, including internal passages and threaded areas that may receive uneven coverage with conventional electroplating. It is useful when coverage consistency, corrosion protection or controlled dimensions matter.
The phosphorus range changes the coating's properties. High-phosphorus deposits are selected when corrosion resistance and nonmagnetic behavior are priorities. Low-phosphorus deposits provide greater as-plated hardness and wear resistance, while medium phosphorus is a general-purpose balance. PTFE composite and post-plating heat treatment are additional options when the part's function calls for lower friction or a specified hardness response.
Surface preparation is specific to the substrate. Steel, stainless steel, aluminum, copper, brass and bronze require different cleaning or activation steps before plating. Send the alloy designation when known, along with a drawing or photos, the required coating thickness, finished dimensions and any areas that must be masked. These details help the team assess adhesion, fit and process suitability before work begins.
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.
Electroless nickel options include low-, medium- and high-phosphorus deposits, PTFE composite coating, bright or satin appearance, selective masking, stripping and replating, and post-plate heat treatment. The recommended combination depends on the base alloy, service environment, wear conditions and dimensional requirements.
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.
The review begins with photos or a drawing, the base metal and alloy if known, quantity, application and any coating specification. The team evaluates the required phosphorus range and thickness, discusses masking or heat treatment where appropriate, and provides a written quote. Approved parts are then cleaned, activated for their substrate, plated in a controlled bath and inspected for coverage and thickness.
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.
After the quote is approved, wait for the shop's quote number and shipping instructions before sending parts. Protect machined faces, threads and ports by wrapping components separately, preventing metal-to-metal contact and using ample cushioning. Include a parts list, contact details 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.
Projects connected with Adelanto may involve equipment maintenance, fabrication, transportation-related components or general industrial applications. Parts such as machined housings, fittings, shafts and threaded hardware can be evaluated for electroless nickel when their operating conditions call for uniform coverage or added surface protection. These are possible applications, not claims of local projects or customers.
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.

We'll tell you what the metal is, what it takes to bring it back and what it costs. A written quote usually comes back within 24 business hours, and there's no obligation.
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.

Preserve coating performance with application-aware handling.
The appropriate cleaning method depends on the coated component's use, the surrounding assembly and the chemicals or conditions it encounters. Follow the maintenance requirements for the equipment or part rather than assuming that a decorative-metal cleaner or abrasive polish is suitable for a functional nickel-phosphorus coating.
During handling and installation, protect precision surfaces, threads, sealing faces and machined dimensions from impact or abrasion. If the part operates in a corrosive, high-wear or high-temperature environment, confirm that the selected coating chemistry and any heat treatment match the service requirements.
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
Review common questions about coating chemistry, base metals, dimensional control, preparation and project timing.
The deposit forms through a chemical reaction rather than electrical current, so surfaces reached by the solution can receive a more uniform layer. Threads, bores, blind holes and recessed areas can therefore be coated more consistently than with conventional electroplating.
High phosphorus is generally selected for stronger corrosion resistance and nonmagnetic behavior. Low phosphorus is harder as plated and is often considered for wear. Medium phosphorus provides a balance for general-purpose applications. The part's operating conditions and requirements should guide the selection.
Yes, both are listed base metals, but each needs its own preparation. Aluminum receives a zincate pretreatment, while stainless steel requires a nickel strike to address its passive oxide layer. Provide the alloy grade when available so the preparation can be evaluated.
Yes. Electroless nickel builds on every surface the solution reaches, including internal diameters and threads. The required thickness must be considered against the finished dimension, and areas that must remain uncoated can be discussed for masking.
Written estimates generally take 24 to 48 business hours. Standard production is typically 3 to 5 weeks. Expedited production may be 5 to 7 business days, subject to review and availability.
It depends on the part. Older fixtures and hardware are often better made than what you can buy today, or simply can't be found anymore. Send us photos and we'll give you an honest answer, even if that answer is to buy a new one.
