If the magnet sticks, the item is usually steel or cast iron, with a brass plating. If the magnet does not stick, you can test further by scratching a hidden area with a sharp tool. If you see a shiny yellow scratch, the item is likely solid brass. If you see a silvery scratch, your piece is likely white metal (zinc).
Chipping equals too hard and brittle for the steel type. tempering at 20-30° higher should help.
Bending and staying bent ( rolling) equals too soft a blade. Repeat the HT if the bend/roll is severe and has little or no return at all.
Flexing and returning shows a proper HT for the steel type.

How do I tell if something is real brass
If you hold a magnet while fighting an object and feel the distance, you know that the part is covered in steel. When there is no attraction, each piece is made of solid brass. This is because the base metal is invariably iron or steel, which experts say are magnetic.
How can you test brass at home
Another quick and easy way to tell if it’s metal is to place a brass magnet on top of it. It doesn’t have to be a particularly complex magnet; You can use a very magnet from your refrigerator. Solid steel is not magnetic. If a magnetic field sticks to your brass, there is no doubt that it is brass or some other material.

How can you tell if its brass or gold
Apply acid to the metal.
Apply concentrated acid to the metal. Brass reacts with acids, unlike gold coins. If you see a bubbling discoloration where the acid has literally been applied, your part is brass. If there is no change after the acid request, you are blessed with gold.
Will a magnet stick to real brass
Brass is a reasonable mixture of zinc (Zn) and base material (Cu). These two elements are far from magnetic. When we mix zinc oxide and copper to make a brass mixture, we also end up with a non-magnetic compound. Thus, brass could not be called magnetic.
How can you tell if a sample is real brass
When tested, the steel does not change color and does not form crystals. However, pickling it in vinegar makes it more comfortable to see its true color, making it easier to spot the copper tint.
What is brass
Brass is a metal composed of copper and zinc, valued for its beauty, strength and durability since ancient times. The color options are the result of a slight selection of proportions of copper, but zinc.
Is brass a fake gold
Brass is certainly not gold; Any alloy based on copper, that is, zinc, is a fake. If there is a lot more copper in the piece, it will give a whiter tint, and more zinc will give a whiter tint. Determining whether a product is made of metal is quite simple.
How can I tell the difference between copper and brass
Copper won’t do much, but brass will definitely sound loud and clear. Sound is perhaps the most reliable way to test the difference between copper and other metals. Thanks a lot! I have an apple butter teapot and I would like to know if it is a work of art in brass or copper. Is there a test I can take that will tell me one way or the other?
