Final answer:
Copper and brass are non-ferrous piping materials, known for their conductivity and resistance to corrosion. They are widely used for piping as well as in electrical wiring and manufacturing musical instruments.
Step-by-step explanation:
Copper and brass are examples of e. Non-ferrous piping materials. These materials do not contain iron (Fe) and are known for their resistance to corrosion and their ability to conduct heat and electricity. Copper, with the chemical symbol Cu, is a soft, malleable, and ductile metal, which makes it an excellent choice for piping due to its high thermal and electrical conductivity. Brass, on the other hand, is an alloy of copper and zinc, which is highly malleable and has acoustic properties making it ideal for applications such as musical instruments. Both copper and brass are used extensively in a variety of applications beyond piping, including electrical wiring and manufacturing musical instruments.
