One could measure the melting point, electrical conductivity, specific heat capacity, or other physical property. These properties would be different between pure metal and alloy, and data could be compared with that in the literature.
Also, many other chemical possibilities exist exploiting the reactivity difference of individual elements. (eg boiling in NaOH would dissolve Al but not Fe).
If one had access to a spectrometer, one could easily and accurately determine composition.
pure nickel coins will stick to a magnet like canadian nickels also if you have a nickel coin with some other alloy lets say copper and an aluminum coin usually aluminum coins are really much lighter in weight also aluminum coins are extremely light weight
Brass is a much softer alloy than bronze. The term "brassy", which refers to the sound that the metal emits, explains the sound it emits. Bronze has a more tonal quality to its sound.
Most jewelers can tell the difference between zirconia and real diamonds right away.
Well, the difference between gold and gold overlay, is that the gold 24k it is pure yellow gold metal; and yellow gold alloys it is 22k thru 10k Rhodium Plated. But is not white gold plated. Because it is yellow gold alloy's include copper, and Rhodium plated. That it is gold overlay.
You can tell the difference between 1s subshell and 3s subshell using quantum numbers and electron configuration.
stainless is steel. aluminum is aluminum

Grab a small magnet. It will stick to stainless steel - it won't stick to aluminum.
Yes there is. I would tell you what thay are, But I need to know the year and what size engine.
Use a magnet. Magnets stick to steel but don't stick to aluminum. Stainless is very weakly magnetic at best. Best to identify aluminum from stainless by weight (aluminum is much lighter) or by hardness (aluminum is much softer; scratches more easily). ***************** Though magnet test can show the difference between magnetic steel and aluminum, it cannot show the difference between non-magnetic steel and aluminum. In this case you can tell the difference by 1. weight , since aluminum has density 2700 kg/m3 and steel (magnetic or not) 7500 2. hardness, using a knife or something similar, since aluminum is softer than steel
You can tell by the heads. 5.7 has aluminum (silver) 4.3 has steel heads (darker grey or painted black.)
Someone has already mentioned using a magnet to determine whether it's steel or aluminum, but another way is the weight. I own one of the steel variety (shot it just this afternoon!), and it is a chunk!! You can definitely tell the difference.
Aluminum and tin are both metals and are both elements on the periodic table. Aluminum is a better conductor of electricity. Tin is too weak to be wired and used for manufacturing, however aluminum is not.
Can you tell the difference between Vyvanse and Concerta in a drug test
how can you tell the difference between a tortoise and a turtle by shell in picture
hyper sliver finish looks very very coool but the other one just looks cool....
Vending machines have laser scanners that can tell the difference between the bills.
