Ways to Distinguish Your Copper Scraps From Brass Scraps

• Check the Color

One of the easiest ways to differentiate between copper and brass is by looking at the color. Copper has a distinct reddish-brown or orange hue, similar to a new penny. Over time, it develops a green patina due to oxidation. Brass, on the other hand, has a yellowish-gold appearance. The higher zinc content in brass gives it this bright, golden sheen. If your metal piece leans towards a more golden tone rather than red, it’s likely brass.

• Use a Magnet

Copper and brass are both non-magnetic metals, but this test can still be useful. If you place a strong magnet on your scrap and it sticks, then you’re likely dealing with something that isn’t pure copper or brass. Some brass alloys contain small amounts of iron or other magnetic elements, which may cause slight attraction. However, if the magnet does not stick at all, you can proceed to other distinguishing methods.

• Look at the Weight

Brass is denser and heavier than copper due to its zinc content. If you have two similarly sized pieces of scrap, pick them up and compare their weight. The heavier one is probably brass.

• Check for Markings or Labels

Manufacturers stamp or engrave markings on metal objects to indicate their composition. Check pipes, fittings, or electrical components for labels such as ‘Cu’ (copper) or ‘Br’ (brass). If you’re dealing with industrial or plumbing scraps, these markings can save you a lot of guesswork.

• Listen to the Sound

If you have a larger piece of metal, give it a light tap with another metal object. Copper produces a deeper, more muted sound, whereas brass emits a higher-pitched, ringing tone. This technique might take some practice, but experienced scrap metal buyers use sound as a quick identification method.

• Conduct an Acid Test

For a more scientific approach, you can apply a few drops of diluted nitric acid to a small section of the metal. Copper will turn a greenish-blue when exposed to acid, while brass will develop a more brownish hue. Be sure to wear protective gear and conduct this test in a well-ventilated area.
