Ed,
Do you have a table of specific weights by alloy? All I have is a metric
reference and it is not specific enough to be able to identify unknown
material well.

You need to know the precise weight and volume, which rules out
checking metal in scrapyards and very likely at home unless you are
equipped as an analytical chemist (or a drug maker). The quick,
traditional method for steel is to grind it and compare the sparks to
known samples or a chart. For scrapyards bring a magnet and a small
file.
