Brass is an alloy that uses copper and zinc, as well as secondary elements such as iron or aluminium. It was discovered millenia after bronze, as zinc is way less common. And,
despite having been used a lot during the Roman Empire, it was only after the industrial revolution mid XIXth century that brass was massively adopted and employed. Brass is known for its
high malleability, which makes it perfect to be cast into a mold and then be mass produced, which suited the new technologies being developed at the tme.
Brass is commonly employed in situations where low friction is a must. For example, locks and gears, as well as ammunition tend to be made of brass.
It also has acoustical properties, and can be found in drum cases and other instruments such as trumpets. And, due to a high magnetical resistance, many clock and watch components are
made of brass.
For centuries, mankind has used brass for decoration, mainly for its goldish color, which makes it a perfect replacement for the more expensive gold.
Also, like its sibling bronze, brass sports a high resistance to corrosion, making it suitable for many hazardous applications such as plumbing (being in constant contact with
water) as well as nautical equipment.
