What are the differences between copper fittings and brass fittings?

Copper fittings and brass fittings differ in material composition, properties, and applications. Copper fittings are made from pure copper, offering exceptional electrical and thermal conductivity, making them the preferred choice in fields requiring specific material properties, such as water lines, medical applications, gas transmission, and heat exchangers. On the other hand, brass fittings are made from a copper alloy containing zinc, which not only retains the excellent characteristics of copper but also significantly enhances strength and hardness due to the addition of zinc. This makes brass fittings highly adaptable and durable, and they are widely used in plumbing systems, automotive manufacturing, and various mechanical equipment.
