note_altKUPRAL 7: CuAl10Ni3Fe2-C – Engineering Excellence for the Harshest Conditions
When industrial and marine environments demand more than just strength, KUPRAL 7 (CuAl10Ni3Fe2-C) steps in. Produced with Çorum Bronz’s advanced casting expertise, this aluminum bronze alloy is specially formulated with Nickel and Iron to provide a formidable defense against corrosion, wear, and structural fatigue.
Why Choose KUPRAL 7?
The metallurgical balance of KUPRAL 7 makes it one of the most reliable alloys in the global market. Unlike standard bronzes, its aluminum-nickel oxide layer provides a self-healing protective surface, making it nearly immune to the corrosive effects of seawater and industrial chemicals.
Superior Load Bearing: It handles high-pressure loads without deformation, making it ideal for structural heavy-duty parts.
Marine Specialist: Its resistance to cavitation and stress-corrosion cracking makes it the gold standard for naval and offshore applications.
Extreme Longevity: Components made from KUPRAL 7 require less frequent replacement, reducing long-term operational costs for your business.
Çorum Bronz guarantees that every batch of KUPRAL 7 meets strict international standards (EN 1982 / DIN 1714). Our commitment to quality ensures that your project—whether it's a deep-sea vessel or a high-pressure pump—operates with maximum safety and efficiency.
