note_altCuAl10Ni: The Engineering Standard for Corrosion Resistance
In environments where seawater and aggressive fluids are constant threats, CuAl10Ni (2.0975) stands as the ultimate barrier. At Çorum Bronz, we produce this specialized aluminum bronze to meet the rigorous demands of the naval and chemical sectors, ensuring that every component we cast delivers peak performance over an extended lifecycle.
The Nickel Advantage
The inclusion of Nickel in the CuAl10Ni matrix does more than just increase strength; it creates a highly stable protective oxide layer. This layer makes the alloy virtually immune to "pitting" and "crevice corrosion," which are common failures in lesser materials. Furthermore, its excellent resistance to cavitation—the erosive force of imploding bubbles in high-speed fluids—makes it the primary choice for pump and propeller manufacturers worldwide.
Operational Efficiency
Reduced Downtime: High resistance to biofouling and corrosion means less frequent cleaning and replacement.
Precision Casting: Our advanced facility in Çorum ensures that CuAl10Ni is delivered with consistent grain structure, leading to better machinability and finish.
Versatility: From heavy-duty bushings to intricate valve internals, this alloy adapts to your specific engineering needs.
Çorum Bronz is your trusted partner for high-quality CuAl10Ni solutions. All our products are manufactured according to EN 1982 standards and undergo strict quality verification to guarantee reliability for your global projects.
