What do Plating specs MFZn1c, MFZn8-S, etc. mean?

A. Hi John. That's not a spec, it's a code within some spec.
The code "MF" means a ferrous substrate in some specs; "Zn-Ni" means zinc-nickel plating in some specs, "8" means 8 microns plating thickness in some specs. "a3-3" is probably a code describing the chromating requirement but I'm not sure. You must find out the spec number, obtain the specification, and plate in accord with the spec in its entirety.
Good luck!

A. Per your question regarding MFZn2-C, "C" means Yellow passivation.
B means Blue passivation, and K means Black passivation

? I think C may refer to CLEAR and K may refer to Black? Be happy to hear from someone who KNOWS!

A. C means the Zn plating color is yellow, and B means Bright color.

A. Answering my own question...

MFZn2-C is defined in Honda spec HES D2003-05.

How to interpret MFZn2-C (what the M means, what the F means, etc) is defined in Honda HES A3010-05.

Unfortunately, as best I can tell, the "-C" just means "colored chromate" and doesn't indicate clear or yellow.

Hi John. Thanks so much for giving us those Honda specification numbers! This should greatly help out the many posters who made reference to those codes.

Luck & Regards,

A. Hello Cintadi.
It has the sound of a code in Japanese specs for zinc plating plus chromating on steel. But these are codes defined within the specification and will mean very different things depending on what specification they are found in, just as "Type 2 Anodizing" means one thing in MIL-A-8625 but "Type 2 Anodizing" means something utterly different in AMS-2488

I'd inquire if they are referring to JIS H-8610 and JIS H-8625 or to a specific automaker's spec, or some other spec. Good luck!

A. Hi Angie. I believe that that one might be a Mitsubishi Motors spec for zinc plating on a steel substrate. Good luck!

Regards,

A. MFZn1-C means:

MFZn: Zinc plating on base of Steel
1: Means 5 micron Min. plating thickness
C: Yellow color

A. Hi Muhammad.

It has the ring of a Honda spec, so if you have no reason to believe otherwise, please contact Honda for the spec. You cannot offer plating to a spec. without having the spec. in hand, so finding out what the acronyms stand for isn't the answer anyway. Good luck!

A. Hi cousin. Sorry, but we might be having language translation difficulties. You already said it's a Honda spec. for Zn-Ni plating with 6-10% nickel, a minimum of 8 microns in thickness, and bright in color. Courtesy of John Tak's posting, the Honda spec numbers may be HES D2003-05 and HES A3010-05. But if you're asking for the spec to be put on line or emailed to you, sorry, no one is allowed to do that except your Honda buyer; the spec clearly states on every page:

Sorry but you must contact your Honda buyer for those specs. Good luck!

A. Hi Puma ,

'MFZn8Cr3' means:

Zn - Zinc plating
8 - Thickness 8 microns
Cr3 - Trivalent Chromate Passivation

Regards,

My guess is either that there's a typo there and what you wrote doesn't specify a thickness; or that it's a Honda spec. where the 2 means class 2 and 8 microns. But please don't guess :-)

Regards,

We've moved on from guessing what finish might be implied by a code within an unspecified specification ... to conjecturing what requirement might once have been underneath a smudge mark :-)

C'mon folks, misunderstanding is the #1 cause of financial loss in business; proceeding without clarification from your customer is foolish.

Regards,

A. I work within the Honda organisation and have access to the specs.
I can confirm that MFZn2-C translates as:-
Electroplate, ferrous, Zinc, plating grade 2, Coloured chromate.

A. Shripad,
If it's a Honda specification, the best place to get it would be from Honda themselves.

A. Kanhaiya,
Maybe you've gotten the idea from the replies to the older similar questions below, but the best thing to do in a situation like this is go back to the CUSTOMER, ask what spec or standard the plating grade comes from, if they can give you a copy of that spec or standard, and if not where you can get it from.

A proper drawing should have the relevant spec or standard listed right on there.

A. Hi Muhammad. No, they are not the same.
Thank you for writing in American english, but I think we're having language difficulties, because people have repeatedly tried to make the same two points.

1. Codes like "AAA", "ED", "SAD", and "MFZnIII" mean nothing at all out of context. "III" could mean "trivalent chromate", it could mean "level III inspection", it could mean "for type III (severe) exposure
2. Offering a price quote on something, let alone trying to supply it, without the specification in hand is a problem.

Luck & Regards,
