Brass is an alloy made of copper and zinc. The color of brass can vary from dark to light based on the zinc content; more zinc content produces lighter brass. Brass is prized for its corrosion resistance, however it is quite soft so it is not suitable for all applications. Brass conducts electricity and is also a good conductor of heat.
