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.
Successful project planning starts with the information that defines the component: alloy, geometry, quantity, target thickness, tolerances and intended use. These details let DMC assess the process before parts are shipped.
Bring function, dimensions and chemistry into one clear plan.
The process review should identify where solution access is clear and where it is uncertain. This is especially important for enclosed channels, blind holes and closely nested features.
The most useful coating selection is the one that fits the part's documented needs. Provide the expected environment, contact conditions, thickness and substrate so available options can be reviewed.
Include any customer approval sample, inspection report or documentation requirement in the initial request. These details can affect how the project is planned and quoted.
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.
Before production, align the part drawing, coating callout and purchase requirements. Conflicting thickness or treatment notes should be resolved before the order is scheduled.
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.
A clear process route follows from a clear specification. Confirm alloy, drawing revision, quantity, thickness, critical features and intended service before approving production.
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.
Send parts only after receiving details are confirmed. Keep different alloys and part numbers organized, protect delicate features and attach the packing list. Use protective separators between custom components and confirm the shipment contents against the approved order.
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.
An application review should connect custom industrial components built to drawing to actual operating demands. Corrosion, wear, lubricity and fit are separate concerns, and their importance varies by component and service. Custom parts benefit from a drawing package that clearly separates critical dimensions from general dimensions.
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.
Not sure what your part needs? Send us a photo.
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.
Send a photo or drawing and receive a no obligation quote within 24 hours.
Every part leaves our shop backed by our craftsmanship guarantee. If you are not satisfied, we make it right.
Single prototypes or full production runs, shipped to us from any state and returned insured.
Most projects are completed within 3 to 5 weeks. Expedited Orders: 5 to 7 business days. Contact us for availability.
Avoid unnecessary damage to functional coating areas.
Avoid stacking precision components directly against one another. Protect contact faces and threaded areas so handling does not damage the finished surface. Compare the unpacked component with the drawing before assembly begins.
Where the part sees repeated sliding contact or chemical exposure, maintenance intervals should reflect those conditions. Seek a technical review if actual service differs from the original specification. Keep the current drawing and inspection requirements with the component's maintenance records.
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 cover coating chemistry, substrate review, dimensions and practical details that can help define a plating request.
Documentation requirements should be stated in the quote request. Identify any thickness readings, test reports, certificates or customer forms required for the order.
Yes. The deposit adds material to coated surfaces. Identify bores, threads, mating faces and all critical tolerances, and clarify whether dimensions apply before or after plating.
Standard production is generally 3 to 5 weeks after the order is approved and scheduled. Confirm the current schedule with the quote because process scope and shop capacity can affect timing.
Copper alloys such as brass and bronze can be evaluated, but the specific alloy and surface condition must be reviewed. Preparation is not assumed to be identical across copper-alloy grades.
Include the complete specification and revision with the quote request. The requirements for chemistry, thickness, inspection and post-treatment need to be reviewed before compliance can be confirmed.
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.
Yes. We work with hotels, casinos, restaurants, architects, contractors and manufacturers, as well as homeowners. For businesses we can plate a whole project to one finish so every piece matches.
