Which commonly used plumbing material is known for its durability and corrosion resistance?

Brass is recognized for its exceptional durability and corrosion resistance, making it a popular choice in plumbing applications. This metal alloy, primarily composed of copper and zinc, exhibits excellent resistance to rust and tarnish, which is critical in plumbing systems that are often exposed to moisture and varying temperatures. Its strength allows it to withstand high pressure, and it has good malleability, making it suitable for crafting fittings and fixtures that must endure wear over time.

In contrast, PVC, while lightweight and resistant to corrosion, does not have the same durability under high-temperature conditions and can become brittle over time. Cast iron is known for its strength and ability to absorb sound but is more prone to rust if not properly maintained. Galvanized steel, though initially resistant to rust due to a zinc coating, will eventually corrode over time, especially in damp environments, as the zinc wears away. Hence, brass stands out as the superior choice for applications demanding a reliable and long-lasting plumbing material.
