Bright V Dull Electroless Nickel
Bright V Dull Electroless Nickel
(OP)
I've done a little searching but not come to a comprehensive answer so I'm asking for some help.
We currently have a standard note:
ELECTROLESS NICKEL PLATE, .0003-.0005 THICK IN ACCORDANCE WITH SPEC MIL-C-26074 OR EQUIVALENT. DIMENSIONS APPLY AFTER PLATING.
My manufacturing engineering manager just asked that I split the note into 2 flavors for aesthetic reasons.
BRIGHT ELECTROLESS NICKEL PLATE, .0003-.0005 THICK IN ACCORDANCE WITH SPEC MIL-C-26074 OR EQUIVALENT. DIMENSIONS APPLY AFTER PLATING.
DULL ELECTROLESS NICKEL PLATE, .0003-.0005 THICK IN ACCORDANCE WITH SPEC MIL-C-26074 OR EQUIVALENT. DIMENSIONS APPLY AFTER PLATING.
I'm concerned this isn't anywhere near properly specifying the distinction.
(I'm OK with accepting the Mil std listed is obsolete which is why we have the 'or equivalent'. We aren't ISO9001 or anything so that aspect isn't too much of an issue. Although if this directly relates to bright V Dull I'm OK with looking at changing it)
I was thinking 'bright' or 'dull' would relate to a class, type or grade or something.
Any help on how to more properly specify this is appreciated, thanks.

RE: Bright V Dull Electroless Nickel
Thanks IRstuff, I saw reference to the stress difference in some info I found. I don't think this will be much of an issue for most of our parts as I can't think of any finer parts that are electroless nickel plated, but I'll flag it just in case. Would I be right in thinking your mirror substrates are relatively delicate?
Just found http
I'm hesitant to change what standard we reference without more research, which I don't seem to have time for, so I'll just use the notes I put in my OP for now.
However, if anyone has anything else to add please do, I can always change it again.

However, now that you've said that I may let people know.

As IRStuff mentioned, this doesn't apply to magnets. Nickel plating on magnets is a whole different situation.
Good luck!
RE: Bright V Dull Electroless Nickel
So just to check, mid phosphorous of 6-8% gets bright or dull, and what do you speck when want the opposite.

RE: Bright V Dull Electroless Nickel
I have to admit, I've never had to spec dull/bright. With mid-phosphorous, the surface finish is cosmetically acceptable but, more importantly, permanent magnets bond well to it. Given the size of the assemblies we make, that's very important.

RE: Bright V Dull Electroless Nickel
We aren't just looking for consistency but actually for 2 cosmetically different finishes.

RE: Bright V Dull Electroless Nickel
Mid phos for semi-bright.
High phos for dull.
But it still won't matter because there is no standard for how bright or how dull.
If cosmetic is a real concern the ONLY way to achieve similar results from plater to plater or batch to batch is to provide them with a sample and tell them to match that each time.
We do the same for anodizing. There isn't a spec or time we can call out for how long it sits in the caustic etch bath because even the same bath will produce different results day to day. But we provide a sample and get very similar results from one vendor to another.

mcgyvr, I agree on the sample idea and had suggested this in similar situations with other finishes, but I don't think they're organized enough to really pull it off or something.
