Cupro Nickel 90/10 hex nuts are essential components in various industrial applications, known for their exceptional corrosion resistance and durability. Composed primarily of copper (90%) and nickel (10%), this alloy offers a unique combination of properties that make it suitable for use in marine environments, chemical processing, and other challenging conditions.
Key Features and Benefits:
Corrosion Resistance: Cupro Nickel 90/10 is renowned for its outstanding resistance to corrosion, particularly in seawater and brackish water environments. This property is crucial in maritime and offshore industries, where fasteners are exposed to moisture and saltwater. Excellent Ductility: These hex nuts exhibit high ductility, making them easy to work with during installation and maintenance. They can withstand a wide range of temperatures, which is essential for applications in various industries. Biocompatibility: Cupro Nickel 90/10 is biocompatible, making it suitable for use in medical equipment and implants, as it does not react with the human body's chemistry and causes no adverse health effects.
Superior Strength: While not as strong as some other alloys, Cupro Nickel 90/10 offers a good balance of strength and ductility, ensuring reliable and long-lasting fastening solutions in many industrial contexts.
Resistance to Biofouling: In marine applications, this alloy's resistance to biofouling, which is the accumulation of microorganisms and marine organisms on surfaces, is an added advantage. This resistance helps maintain the efficiency of systems and reduces maintenance costs. Low Maintenance: Due to its corrosion-resistant properties, Cupro Nickel 90/10 hex nuts require minimal maintenance, reducing downtime and operating costs in various industries. Non-Sparking: In environments where sparks can be hazardous, such as oil refineries and chemical plants, Cupro Nickel 90/10's non-sparking properties add an extra layer of safety.
