Yes and yes. 6061 is a very common alloy for anodizers to do.

What's the application?

Is aluminum anodizing tough enough to withstand a dishwasher? Will 6061
anodize well?

Thanks,

Whatever they use for the Calphalon definately does not hold up under
regular dishwasher use.

6061 is anodized all the time but how it stands up to a dishwasher
depends on the SWMBO's opinion. I landed in some serious dodo when I
washed a couple of "antique" aluminum jelly glasses.

The anodization lasts pretty well in the dishwasher but any color added to
the coating will come out with repeated washings. The spun cups from the
'50s lost a lot of their color when washed several times but the anodizing
itself still remained.
Almost any of the aluminums take anodizing well and 6061 is a standard for
the electronics industry for parts and most of those parts are anodized to
keep from corroding.

Kitchen gadget. Dishwasher safe would be best. Given the other responses,
looks like I'm forced to go to stainless.

Very helpful - thank you very much!

Maybe so. Just be aware that there are many different annodizing
processes
out there with widely varying corrosion protection levels. For example, a
level of anodizing can even be done in a bath of Coca-Cola (phosphoric
acid
anodizing). There are chromic, phosphoric, and sulphuric acid processes
just to name a few. There is also a 'hard coat' specialty process that
produces a very tough surface but it may not be cosmetically suited to
your
project (produces a dull coat). For proper hard coat anodizing, the
sulfuric acid bath is kept very cool and it's done at much higher voltage
than usual.

For an example photo of anodized kitchen ware, see:
http://www.fortwayneanodizing.com/01.../anodizing.htm

At one time Fort Wayne would anodize sample parts sent in for free to
prospective clients. Haven't done business with them so I cannot speak
for
their quality.

I just realized how true that is! I wonder what the process parameters a
temperature, concentration, current per square inch, time....

I don't know either, but I think Magnadize will do a sample hard coat WITH
teflon impregnation, which will last in a dishwasher, and can rattle around in
a drawer full of sharp high carbon knives for years without damage. I have a
one inch square sample, and nothing will stick to it, within reason. Everything
just beads up, and if you try to scratch it, your fingernail (or concrete nail)
just slides off....

Much less expensive in quantity than stainless which is a bitch to even make
one of without work hardening it and ruining a tool. Far better.

I'm off to the store to buy coke! Well, Coke (tm), actually. I don't know from
coke.

I don't have any tables listing temperature, but it seems that phosphoric
annodizing has been done from 20 to 120 volts DC, inclusive. Honeycomb cell
size varies proportionately with voltage. I have a microscope photo or two
I could scan and email you if you want to see them. Email me...

As for process time, it's self limiting by the resistivity of the layer as
it builds up.

Never tried it in Coca-Cola, just heard about it somewhere...

Is there any advantage to phosphoric acid anodizing over the more common
sulfuric?

Ted


No, sulfuric produces a tougher coating. Sulfuric acid is cheap and widely
available. Good durability and economics make it the most common choice for
mechanical parts.

I understand phosphoric is occasionally used as a base coating for
electroplating (at least so says an older ALCOA publication).
