Clean the metal if necessary. Both brass and copper develop a patina with age, usually green but sometimes other colors.
Hold the metal under white light. If the metal is highly polished, you may see false colors due to reflected light.
Identify copper’s reddish color.
Inspect yellow brass.
Learn about red or orange brass.
Identify other 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 to tell real brass
Artificial polishing or brass: gold and brass fittings

How to determine a brass grade
SAE Bolt Ratings – bolt strength standards using U.S.
Bolt Metric Grades – Metric bolt grades are defined according to ISO (International Organization for Standardization) rules.
ASTM bolt classes. The general ASTM grade is defined by the American Society for Testing Materials and Bolts.
How can I tell if something is made of brass
Don’t let the room stay so damp. Soaking will chip a person’s paint. Only
work with the hatch increases water heating. Due to the heat of hot potable water, metal expands faster than paint and all paint cracks and/or flakes off.
Use only a soft cloth and soap to remove it. We got lucky with Brasso on this occasion!
How can you tell real brass
With the right magnet, you can see the difference. If you apply a magnetic field to an object and feel it being attracted, you know the part is still covered in brass. If there is no attractor, then the part is all-metal.
How can you tell if it’s brass or bronze
Perhaps the most useful way to tell brass from bronze is by their color. Brass usually has a muted yellow tint similar to brushed gold, making it a good material for tables and light fixtures. Bronze, on the other hand, almost always looks reddish, matching brown.
How can you tell if it’s copper or bronze or brass
Copper has a characteristic red-brown color. Brass has an enhanced yellowish-golden hue. Bronze, on the other hand, tends to be duller compared to gold or sepia and tends to show faint rings on the surface. You can tap on the metal to see if it’s copper or an alloy.
Will a magnet stick to brass
Metals that magnets do not attract
Some other naturally occurring metals, such as aluminum, copper, lead, gold, and silver, do not attract magnets because they are weak metals. However, properties such as iron and stainless steel can be added to these mining crops to make them durable.
