About Aluminium Bronze Valves
What Is Aluminium Bronze and Why Is It Used in Valves?
Aluminium bronze is a copper-based alloy that contains aluminium (typically 5–12%) and often small amounts of iron, nickel, or manganese. This composition gives it a unique combination of strength, corrosion resistance, and durability, especially in marine and corrosive industrial environments. Aluminium bronze is highly valued in valve manufacturing where mechanical strength and resistance to aggressive media are essential.
Why Aluminium Bronze for Valves?
- Exceptional Corrosion Resistance: Especially in seawater, chlorinated water, and chemical-rich environments.
- High Strength & Wear Resistance: Stronger than traditional bronzes and brasses, making it ideal for heavy-duty use.
- Excellent Cavitation and Erosion Resistance: Suitable for high-flow, turbulent fluid conditions.
- Non-Sparking & Non-Magnetic: Safe for use in explosive or electrically sensitive environments.
- Good Biofouling Resistance: Resists marine organism build-up better than many other metals.
Common Applications of Aluminium Bronze Valves
- Marine & Offshore: Seawater systems, bilge and ballast lines, cooling systems, and shipboard valves.
- Oil & Gas Industry: Especially in offshore rigs and refineries exposed to aggressive chemicals.
- Desalination Plants: Performs well with saline water and pressure systems.
- Chemical Processing: For corrosive fluids where standard metals may fail.
- Fire Protection Systems: In systems where corrosion resistance and longevity are critical.
- Mining & Pulp Mills: Resistant to abrasive slurries and chemical exposure.
