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.
Address demanding component requirements with electroless nickel in Irvine.
Where a component has a defined inspection standard, include it with the drawing. Thickness locations, acceptance limits and reporting expectations should be understood before the coating scope is finalized.
Certified, Approved and Verified
Make the service environment part of the specification
Bring service exposure into the first discussion.
An inspection requirement should define where thickness is measured and what acceptance range applies. Include the test method or customer specification if one is required.
An inspection plan can include thickness readings, visual criteria or dimensional checks. Identify which records are required with the finished order.
Explain the contact pattern and counterface material when the main goal is to manage friction or wear.
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
Available options include several nickel-phosphorus ranges and, for suitable applications, a PTFE composite. The final scope depends on the alloy, thickness, operating environment and any required post-process treatment. For cast bronze, describe the casting condition and any machining or repair performed afterward.
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
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
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
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.
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.
Electroless Nickel
- Uniform thickness on any shape
- Coats inside bores and threads
- Excellent corrosion resistance
- Holds tight finished dimensions
- Satin to bright functional look
Electrolytic Nickel
- Brighter decorative appearance
- Lower cost on simple shapes
- Ideal base layer under chrome
- Thicker on edges, thinner in recesses
- Best for visible, open surfaces
Hard Chrome
- Extreme hardness and wear life
- Low friction on rods and shafts
- Can be ground back to size
- Struggles in recesses and bores
- Best for straight, exposed surfaces
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.
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.
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.
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.
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.
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.
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
Part documentation sets the direction for production planning. DMC reviews the alloy, quantity, dimensions and service requirements before confirming whether the requested chemical deposit is suitable. For cast bronze hardware, also clarify casting surface condition and alloy grade. Do not rely on a general material label when the alloy grade is available.
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
Prepare the components only after the shop confirms the receiving details. Secure heavy pieces against shifting and keep delicate features away from hard packaging surfaces. Support cast projections evenly instead of placing the component's weight on one feature.
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.

Trusted by Professionals
From custom builders to industrial manufacturers, our clients trust us to deliver the same result every time.
Who We Serve
Where Electroless Nickel Earns Its Keep
New production hardware, replacement parts and custom prototypes can share a plating process but still need different specifications. State the component's role and whether it is new, refurbished or part of a repeat order. Cast surfaces may need closer review than a machined surface with a known finish.
Machined Components
CNC parts with tight tolerances, where the coating has to go on evenly so the part still fits after plating.
Industrial Equipment
Valves, pump housings, shafts and fixtures that need corrosion protection inside passages as well as outside.
Automotive and Motorsport
Brackets, fuel system fittings, brake parts and engine components protected from heat, fluids and road salt.
Marine
Fittings, pump parts and deck components where high phosphorus nickel stands up to constant salt exposure.
Molds and Tooling
Plastic injection molds, dies and fixtures that need a hard surface, clean release and protection from corrosion.
Hardware and Fasteners
Threaded parts, hinges and fittings coated all the way into the threads for smooth assembly and lasting protection.

Ship It From Anywhere
You don't have to live nearby to work with us.
Customers all over the country pack their parts and ship them to our Oceanside shop. We finish them, inspect them and send them back insured. It starts with a few photos.
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.

Care of cast and machined surfaces
Support cast projections during handling.
During assembly, keep tools and fixtures from dragging across finished faces. Protect the surfaces that were identified as critical on the drawing. For cast bronze hardware, avoid loading thin edges or projecting features.
Choose cleaning practices based on the fluid, temperature and contact conditions. Confirm them against the component specification and the equipment maker's guidance. Compare service wear with the documented operating conditions. Support cast projections during maintenance so thin sections are not overloaded.
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.
Yes. Deposit adds material to coated surfaces and can affect bores, threads, sealing faces and mating clearances. Identify critical dimensions and state whether they apply before or after plating.
Identify each material and part number separately. Different substrates can require different preparation, so the process route should be reviewed for each component rather than assumed to be identical.
Separate components and protect threads, bores, sealing faces and precision edges from impact or abrasion. Label each part number and include the packing list and approved quote reference.
Include the drawing, material grade, quantity, target thickness, critical dimensions, masked areas and intended service. Photos and applicable customer specifications can clarify unusual features.
