You can tell the difference with the help of a magnet. If you hold a magnet against the item and feel a pull, you know the piece is brass plated. If there’s no attraction, then the piece is solid brass. That’s because the underlying metal is usually iron or steel, both of which are magnetic.
How can you tell real brass?
Solid brass is not magnetic. 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.
How can you tell if something is brass or bronze?

Brass is a mixture of zinc (Zn) and copper (Cu). So, brass is not magnetic. Like aluminum, copper, and zinc, brass does interact with moving magnets. In the video below a brass plate on a pendulum will move rapidly in the absence of a magnet.
Does brass turn green?
