I'm no expert on this matter but I fear you can only tell pure aluminium from alloys by chemically analysing it or by testing its physical properties and comparing it to those of pure aluminum, I myself am looking for a way to purify alloys so I can make my own alloys, for you to be able to judge my answer I'll tell you that I am an industrial enginering student in my second year of university/college.
run a small test current of electricity through the items and measure the resistance ... silver is a bit more electroconductive and offers less resistance.
An alloy is a mixture of two metals

An aluminium bronze is an alloy of copper containing 5 percent to 10 percent aluminium.
Even though brass is a copper alloy, generally made up of about 95% copper and 5% zinc, copper is a softer metal. Copper has a higher heat capacity though, meaning than brass heats up more quickly than copper.
There are many types of alloys. They are: 1. Aluminium alloy 2. Metallic alloy 3. Plastic carbon and so on. If its a metal alloy, its compositions are iron (ferrous), aluminium, copper, nickel..etc. Use magnet to check the metal or use Ultrasonic test to find out metal in alloy.
No. Silver is too soft to have any general engineering use.
German nickel or nickel silver is an alloy that contains nickel, zinc and copper. That makes it a type of brass which is an alloy of copper and zinc. Pure nickel is an element, not an alloy.
An alloy wheel is a wheel rim made from an aluminium alloy.

The colour isn't a good indication of the strength. Choice of material - steel or aluminium alloy, and design will be more important for strength than colour.

Sterling is 92.5% pure silver. .999 Fine is 99.9% pure. Sterling silver =92.5 silver + 7.5% alloy Fine silver usually mention "Ag 99.9 " ,means with 99.9% silver.
Y alloy is a nickel that has aluminium alloy in it. This was made in World War 2. Uses? ..
Ore is raw material, alloy is combination of metals
