Brass is a metal alloy composed primarily of copper and zinc. It is known for its gold-like appearance and is commonly used in musical instruments, decorative items, and various engineering applications. The proportions of copper and zinc can vary to create different types of brass with varying properties.
The composition of brass typically ranges from 60-80% copper and 20-40% zinc. Small amounts of other metals such as lead, tin, and aluminum may also be added to improve specific properties.
Properties of Brass
Brass exhibits a range of desirable properties, including:
Good malleability and ductility, allowing it to be easily formed into various shapes
Corrosion resistance, making it suitable for use in marine environments
Cartridge cases for firearms due to its low friction and excellent heat conductivity
