This is a pivot ball from a ceiling fan. It's Non magnetic, does not spark with a grinder. So it's Alum, Non Magnetic SS, or Brass but it's weight at almost 1lb would say it's not Alum. So brass or SS. What say you?

Brass should show a yellowish color when ground down. I vote for stainless. (It might be Kryptonite, though)

It's aluminum. Did it spark? How heavy is it?
If it didn't spark, it's aluminum.

Cast Aluminum
Not all brass is yellow there is something called white brass found in higher end sink faucets handles.Originally Posted by spinroch
White nickel brass is a grade of nickel silver. The white brass used for castings where a white color is desired may contain up to nickel. The 60:20:20 [Cu:Ni:Zn] alloy is used for white plaque castings for buildings. Nickel brasses known as German silver are copper-nickel-zinc white alloys used as a base metal for plated silverware, for springs and contacts in electrical equipment, and for corrosion-resistant parts. Extra-white metal, the highest grade, contains 50% copper, 30 nickel, and 20 zinc. The Federal Trade Commission prohibits the use of the term German silver in the marketing of silver-plated ware.
I'm pretty sure this is what it is.

It is either cast Aluminum or cast Zinc, but probably Aluminum. There is no reason for this piece to be Cupro-Nickel, and if it was it would not be painted.

I agree with tincan, it is to heavy to be aluminum or die cast.

I've seen white brass that doesn't turn yellow when scratched, at least the stuff I dealt with.... a couple of nice decorative plates.
I do not spew profanities; I enunciated them clearly, like a f***ing lady.

It's a part that is not very visible in a mass-produced, commodity item. Therefore, think low cost, cheap materials.
It is made by die casting, too....easy to make by the gazillions and easy to cast in intricate details.
Therefore: a zinc alloy, sometimes called "die cast" by the scrapyards. The exact composition of the zinc alloy could be anything, and your quickest way to tell is to hit it with a XRF gun next time you're at a yard that has one.

Id say "diecast" too. That's if its sorta heavy.
If its weight sorta corrosponds with ali, then ali.
On a side note:
At first I was thinking you ment the electric motor bearings. Most often these bearings are bronze.
I have found 'white bronze' in two items so far. A part for a cows milking machine and the body of a welders gas torch regulator.
Sawmillineng is most correct i I think. You have to have the mind of the person who designed the item in the first place. Particuary with finding Gold in electronics.

Zinc Diecast.....if it looks like cast aluminum but it is too heavy to be aluminum. Commonly found in Cheap faucets, door handles and pulls, conduit connectors, padlocks, lamp parts and most recently wheel weights.
I should be going to the yard this Saturday Ill take it with me and have them hit it with the gun. I'll report back the findings in this thread.
Thanks for all the input.
Took it in today and the answer is Zinc!

That's what I figured they call it zinc/ die cast at my local.

Straight zinc? No alloying metals at all?
Thanks for getting the answer back to the thread. It makes it complete when someone looks at it a year from now!
Jon.
At first he said it was alum. but when I handed it to me he said nope (I guess the weight ruled that out) then hit it with the gun and said its zinc.
