Specify a nickel-phosphorus finish for critical parts with electroless nickel in Hutchinson.

Plan a coating route for mixed geometry components: electroless nickel for Hutchinson components.

Coating thickness affects more than the outside profile. Threads, bores, sealing faces and press-fit areas can all change dimensionally, so the drawing should identify the features that control assembly.

Certified, Approved and Verified

Know when a composite deposit may be relevant

Consider PTFE only when function calls for it.

The deposit changes finished dimensions wherever it is applied. Identify thread specifications, bore sizes and mating clearances, and clarify which dimensions are measured after plating.

Where a component is assembled with a close-fit partner, provide the mating dimension or clearance. This helps determine whether coating build needs to be limited or masked.

State whether the thickness is a minimum or a target range, and identify any dimensions that must be verified after coating.

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.

What We Do

Electroless Nickel Coating Options

The technical review can consider deposit chemistry, coating build, masking and optional composite or heat-treatment requirements. Each option must be evaluated against the component's material and function. For complex fittings, show blind features and narrow recesses in section view.

High phosphorus electroless nickel coating on a valve component

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.

Medium phosphorus electroless nickel on machined steel parts

Medium Phosphorus

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.

Low phosphorus electroless nickel on a wear component

Low Phosphorus

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.

Heat treated electroless nickel for increased hardness

Heat Treated

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.

PTFE composite electroless nickel with a low friction surface

PTFE Composite

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.

Electroless nickel on a part with internal passages and threads

Complex Geometry

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.

Choosing a Finish

Electroless Nickel Compared

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.

What We Can Finish

Base Metals for Electroless Nickel

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.

All chemistries

Carbon and Alloy Steel

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.

All chemistries

Stainless Steel

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.

Our specialty

Aluminum

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.

All chemistries

Copper

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.

All chemistries

Brass and Bronze

Valve bodies, fittings and marine components plate cleanly once activated. The nickel layer protects against dezincification and adds a harder working surface.

Ask us first

Specialty Alloys

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.

How It Works

From Raw Part to Coated and Inspected

Start with the current drawing and exact material designation. The shop can then assess surface condition, coating allowance and any special treatment or inspection requirements. For complex machined fittings, also clarify recess geometry and bath access. Any optional process step must be supported by the component specification.

1

Share the Details

Send photos or a drawing, the material, the quantity and any coating callout on your print.

2

Get a Recommendation

We suggest a phosphorus range and thickness and send a written quote within 24 business hours.

3

Ship or Drop Off

Once scheduling is confirmed, package each component to prevent abrasion and impact. Identify the order clearly and separate parts with different drawings or material grades. Use a rigid divider where projecting features could be bent or struck.

4

Clean, Activate and Plate

Parts are degreased, masked where needed, activated for their alloy and plated in a controlled bath.

5

Inspect and Return

Coverage and thickness are checked, any heat treatment is completed, and parts ship back insured.

Who We Serve

Where Electroless Nickel Earns Its Keep

Application planning should connect complex machined fittings with a measurable requirement. Corrosion resistance, wear behavior, friction and dimensional fit are separate objectives and should be described individually. Recessed features must be visible in the documentation so solution access can be assessed.

CNC machined components coated with electroless nickel

Machined Components

CNC parts with tight tolerances, where the coating has to go on evenly so the part still fits after plating.

Industrial valve and pump parts with electroless nickel

Industrial Equipment

Valves, pump housings, shafts and fixtures that need corrosion protection inside passages as well as outside.

Automotive and motorsport parts with electroless nickel

Automotive and Motorsport

Brackets, fuel system fittings, brake parts and engine components protected from heat, fluids and road salt.

Marine hardware protected with high phosphorus electroless nickel

Marine

Fittings, pump parts and deck components where high phosphorus nickel stands up to constant salt exposure.

Molds and tooling with PTFE composite electroless nickel

Molds and Tooling

Plastic injection molds, dies and fixtures that need a hard surface, clean release and protection from corrosion.

Hardware and fasteners finished with electroless nickel

Hardware and Fasteners

Threaded parts, hinges and fittings coated all the way into the threads for smooth assembly and lasting protection.

    Our Commitment

    Coatings You Can Build Around

    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.

    Controlled Baths

    Bath chemistry, temperature and nickel content are monitored throughout the run so the deposit stays consistent from the first part to the last.

    Right Prep for Each Alloy

    Steel, stainless and aluminum each follow their own cleaning and activation sequence, which is what keeps the coating bonded.

    Thickness Checked

    Coverage and coating thickness are checked against your requirement before parts are released for packing.

    Protected in Transit

    Finished parts are separated and packed so threads, sealing faces and machined surfaces arrive exactly as they left the tank.

    How We Handle Your Order

    • We recommend a chemistry and thickness based on how the part is used
    • Masking is discussed up front for threads, bores and sealing faces
    • Every batch is inspected before it leaves the plating line
    • We call you when something about a part needs a decision
    • Production runs are processed to the same settings every time

    Fast Turnaround Times

    Most projects are completed within 3 to 5 weeks. Expedited Orders: 5 to 7 business days. Contact us for availability.

    Storage guidance for small precision parts

    Store small components in separate compartments.

    Do not stack precision parts directly against each other. Use separators around mating faces, threaded features and delicate projections. For complex machined fittings, prevent loose hardware from contacting finished faces.

    Where the component sees repeated washdown or sliding contact, maintenance intervals should reflect those conditions. Seek a technical review if service differs from the original specification. Do not use abrasive methods without confirming suitability. Keep recesses free of accumulated debris during routine inspection.

    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

    The following answers address process selection, substrate information, coating dimensions and practical details that help define a plating request.

    They can be reviewed, but prior coatings, corrosion, repair work and contamination should be disclosed. The starting surface may affect preparation and process suitability.

    State whether the requirement is a minimum, maximum or target range and identify where it must be measured. Include the drawing or standard that defines acceptance.

    Electroless nickel forms through an autocatalytic chemical reaction and does not use an external electrical current. That changes current-distribution considerations, although the bath must still reach the surfaces that require coating.

    Masking may be considered for areas used in electrical contact, joining or close-fit assembly. Mark the boundaries on the drawing and explain why each area must remain free of deposit.

    Yes. Open and accessible features can be evaluated, while sealed cavities, restricted channels and trapped volumes require specific review. A detailed drawing helps define the intended coverage.

    Send us a few photos of the part from different angles, along with what it is and the finish you want. We look them over and send a written quote, usually within 24 business hours. It's free, and you're under no obligation to go ahead.

    Standard orders take 3 to 5 weeks from the day your parts arrive. If you're on a deadline, ask about expedited service. When the schedule allows, we can finish in 5 to 7 business days.

    Yes. Our workmanship is covered for 12 months. If something isn't right with the finish we put on, call us and we'll make it right.
