# re metal

hi
its very smooth very shiney and heavy
it seems more bright than stainless
i know this hasnt narrowed it down at all
is there any tests i could do to help identify
TIA

1. Spark it on a grinding wheel nd note the color, shape and qty of sparks. 2. Touch it to a magnet. 3. Touch it with a file.

You can get a few more clues by finding out if it is magnetic, measure its specific gravity, see what kind of sparks it generates when pressed against a grinding wheel. These are all pretty easy to do.

What's the procedure for measuring specific gravity, Dan?
Thanks

I dont recall from the original post what shape your metal is, but if you can gewt a small piece, say a cubic inch you can imerse it in water ion a measuring cylinder (if thats the correct term) and notice how mych the water rises. That will give you the volume of the sample. the you weigh the sample and divide the two figures. Weight divided by volume. the number youi get is the specific gravity. Henning

Specific gravity is the ratio of the weight of the metal to an equal volume of water. Lots of ways to do that. One way is to fill a container to the top with water. Then put the object in the water and catch the water that spills out of the container. Then weight the object and the spilled water and divide. Other methods may be easier or less messy for example if you have a graduated container the object will fit into.

And remember that the magnet test is not a yes or no regarding sst.

Hey Rooey,
Maybe the first question is "Why do you want to know?". What do you plan to do with it or use it for that requires specific knowledge? How much of it do you have?
Some simple things to do are to weigh it and note the volume, then compare the weight per cubic inch to a chart of known materials. What shape is it? What does it do when left wet and exposed to air. How well does it conduct heat? What happens when you add significant heat, as in burning or melting it, and at what temperature colour? What happens when you try to grind it?
Take care.

Here's a really nice mystery metal Identification tree: http://www.aussieweld.com.au/arcwelding/page14/page14.htm
Just follow the steps as outlined.
Its part a a good FAQ on welding.
