Plan coating coverage for precision metal parts with electroless nickel in Inglewood.

Evaluate optional composite and heat-treatment needs: electroless nickel for Inglewood components.

Surface preparation begins with knowing what metal is being processed. Aluminum, steel, stainless steel, brass, bronze and copper each require an alloy-specific review rather than one assumed preparation method.

Certified, Approved and Verified

Define the finished dimensions, not just the deposit

Specify the dimensions required after plating.

Do not assume one pretreatment sequence applies to all metal families. The alloy designation and prior surface condition are necessary inputs for assessing substrate suitability.

Where heat-sensitive features or joined materials are present, disclose them before discussing post-plating treatment. The entire component must be suitable for the proposed cycle.

Provide the approved cleaning requirements if the component will be exposed to a specific chemical washdown.

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 process discussion may include phosphorus range, dimensional allowance and special surface requirements. If PTFE composite or a heat-treatment cycle is requested, explain the performance objective and provide the governing specification. For aluminum housings, disclose prior anodizing or conversion treatments before the process is assessed.

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

A process route is selected only after the material grade and coating callout are understood. Prior finishes, masking notes and the required thickness help determine what preparation questions must be resolved. For aluminum covers and machined housings, also clarify alloy-specific activation and prior finish. If a requirement is unclear, resolve it against the drawing before approval.

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

When the project is authorized for shipment, label each part number and protect threads, bores and machined surfaces. Dividers or individual wrapping help prevent movement inside the package. Keep aluminum housings apart from heavier items that could dent their edges.

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

The industry label does not define the coating requirement by itself. For aluminum covers and machined housings, the useful questions concern what the part contacts, how it moves, and which dimensions must remain within tolerance. Aluminum preparation depends on the specific grade and surface history.

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

    What You May Experience Elsewhere

    • One generic chemistry used for every part that comes in
    • No questions asked about tolerances or the finished fit
    • Coating that builds up on threads and blocks assembly
    • Results that change from one batch to the next

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

    Handling aluminum and copper-alloy components

    Prevent scratches on softer alloy surfaces.

    Use clean handling methods and avoid metal-to-metal contact between coated parts. Individual compartments can reduce scratches and impact during movement. For aluminum covers and machined housings, keep internal openings free of packing debris.

    Inspect the part according to its normal maintenance plan, especially where corrosion or mechanical contact is part of the service. Unexpected wear or surface damage should be evaluated. Avoid unapproved chemical substitutions during cleaning. Handle aluminum faces with non-marring tools and avoid contact with harder parts.

    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.

    Different alloys and grades can respond differently during preparation. Exact identification helps determine whether the substrate is suitable and what process questions need to be resolved.

    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.

    Not at all. Most of what comes through our door is home and business hardware: faucets, light fixtures, door handles, cabinet pulls, railings and decorative pieces. We also work for hotels, restaurants, boat owners and manufacturers.

    Tell us what the part is, roughly how big it is, how many pieces you have and the finish you're after. If you know the metal, mention it. If not, that's fine. We can usually tell from the photos.

    Every part is quoted on its own. The biggest factors are condition, the base metal, size and shape, the finish you choose and how many pieces you send. A part with deep pits or broken spots takes more work before it can be plated.
