The difference between brass and aluminium is immediately obvious from the weight and the dull appearance when placed next to a nickel plated brass case. No need to weigh them, brass is three times the weight. Just for the record, we are discussing cartridge cases, the bullet is the bit that comes out of the front of the gun.
Remember that copper is mostly red and brass is mostly yellow. Look for signs of shiny, silvery colors with metals that are softer and more flexible than other metals. If you see these characteristics, you may have aluminum. Check your metal by applying the magnet test again if you suspect that the metal is aluminum.

How can you tell if something is made of brass
Sometimes antique pieces are made from solid brass, but it is also common to see items plated or even wrapped around the brass in a thinner layer. You can tell the price difference with Magnet pro. If you hold the magnet close to an object and feel a slight pull, you know the part is made of galvanized steel.
How can you tell if a piece of metal is aluminum
Pass all the old merciless tests. It is common to weigh a piece of metal, then measure its volume by placing it in a body of water known as water and watching how much the water level rises when you put the metal in it. Density (g) mass classified by volume (ml). If each specific gravity is 3, there should be aluminum around it.
Is brass different from other metals
However, with the right knowledge, finding the metal and separating it from other alloys can be much easier. Brass is a lustrous yellow-gold metal that is quite durable and often used for decorative purposes. It looks a lot like copper at first glance, but brass has several unique qualities that set it apart from others.
Will a magnet stick to brass
Metals that do not have magnets
Some metals in their natural compound states, such as aluminum, copper, brass, gold, and silver, do not attract a magnetic field because they are likely to be weak metals. However, properties such as iron rods and steel can be added to these metals to make them magnetic.

How do I know what type of metal I have
Place the magnet on the steel to see if it is iron or non-ferrous. If you feel your current attraction, the metal you are trying to find is most likely iron. As a rule, ferrous metals are magnetic, non-ferrous metals are non-magnetic.
How do you know if something is brass plated or solid brass
A magnet can be used to determine if something is solid brass or just plated brass. If the part normally sticks magnetically, it is plated. If not, run another test to make sure it’s not actually a metallic coating on another non-magnetic suit. Check by scraping an inconspicuous area with a sharp knife.
How can you tell the difference between yellow brass and red brass
The main difference between NASA brass and yellow brass is the copper content. If you are unsure of the type of brass you are using, take a rasp or file to lightly sand it and note the type and amount of copper filings on the brass.
