Corrosion resistance: brass has a high resistance to corrosion, which makes it useful in damp or corrosive environments. Good electrical and thermal conductivity: brass is a good conductor of electricity and heat, making it a useful material in electrical and thermal applications. Easy to machine: brass is a relatively soft material that is easy to work, making it easy to machine to produce complex parts. Fatigue resistance: brass has good fatigue resistance, which means it can withstand high loads without breaking. These properties make brass a useful material in many applications, such as the production of taps and fittings, clock parts, pipework, jewellery, decorative parts and musical instruments.
