Copper and brass are among the most sought-after metals for scrap metal recycling. However, copper is more valuable due to its higher conductivity and wider range of applications. If you want to make the most money possible for your scrap metal, it’s important to separate these metals from each other. However, distinguishing copper scraps from brass scraps can be a tricky proposition to the untrained eye. This is because they are alike in appearance. That’s why we are here today.
Just Scrap It is a reputable scrap metal company that’s committed to giving unwanted metal and other recyclable materials a second chance. We accept a wide range of ferrous and non-ferrous metals, including copper, brass, iron, steel, aluminum, and more. Our experts know how to tell the difference between two metals. In this guide, we’ll explore some of the ways you can tell the difference between copper and brass.
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.
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.
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.
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.
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.
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.
At the end of the day, any scrap metal that gets recycled helps the environment and puts valuable resources back into circulation.
