Bronze is traditionally made of a mixture of copper and tin. It is more susceptible to cracking than iron, is malleable, and can be cast or machined into valves and other components. Some types of brass nowadays also contain manganese, aluminum, or nickel. Bronze has a rough, porous exterior with small cavities on the surface due to the casting process. It has many benefits, including high ductility, corrosion resistance, and low cost. There are many uses for bronze valves, including safety relief, flow direction control, and shutting off flow.

Corrosion Resistance

Bronze exhibits good corrosion resistance, especially in marine and aqueous environments. This makes it suitable for valves exposed to water, steam, or other corrosive substances. The corrosion resistance of bronze helps prevent degradation and ensures the longevity of the valves.

Strength and Durability

Bronze is a strong and durable material, providing mechanical strength to valves. This is crucial in applications where valves are subjected to pressure, flow, and mechanical stress. The durability of bronze valves contributes to their long service life.

Resistance to Dezincification

Certain types of bronze, such as dezincification-resistant (DZR) bronze, are specifically formulated to resist dezincification—a form of corrosion that affects some brass alloys. This resistance enhances the longevity and reliability of the valves, especially in environments where dezincification is a potential concern.


Bronze is known for its excellent machinability. This property allows for precise manufacturing of valve components, facilitating intricate designs and tight tolerances. Valves often require complex shapes and configurations to control fluid flow effectively, and bronze’s machinability supports this.

Low Friction

Having a low coefficient of friction can be advantageous in valve applications. Low friction allows for smooth operation and reduces wear on moving parts, contributing to the overall efficiency and reliability of the valves.

Thermal Conductivity

Thermal conductivity means bronze valves can efficiently transfer heat. In certain applications, this property is beneficial for maintaining temperature stability within the piping system. Bronze valves can help dissipate heat and prevent overheating in specific industrial processes.


Bronze is a biocompatible material, making it suitable for use in applications involving potable water or where contact with drinking water is a concern. The absence of harmful substances in bronze ensures that it meets safety standards for water-related applications
