Superior Corrosion Resistance

Engineered for longevity, CUAL 10NI5FE4 excels in resisting corrosion, especially in challenging marine and industrial environments. This makes it an ideal choice for offshore structures, ship components, and other applications facing saltwater or chemical exposure. Its chemical composition, particularly the addition of nickel and aluminum, enhances its natural ability to withstand aggressive conditions, reducing the need for frequent maintenance or replacement.


High Strength and Versatile Performance

This alloy stands out for its impressive mechanical properties, including high tensile and yield strengths, substantial elongation, and reliable hardness. It is suitable for components requiring both robustness and adaptability, such as machinery parts and aerospace fittings. Solution treatment and age hardening further strengthen the material, ensuring both structural integrity and flexibility under stress.


Customized to Industry Needs

CUAL 10NI5FE4 materials are offered in various shapes and dimensions, tailored to each projects demands. Whether its cut-to-length rods or specialized plates, the alloy can be delivered in the exact size and shape needed. Combined with a smooth mill finish or customer-specified surfaces, it fulfills the bespoke requirements of marine engineers, manufacturers, and designers alike.
