4. Main Features
C19160 Nickel Bronze has achieved a balance between high strength and good conductivity through alloy strengthening treatment. While maintaining certain conductivity, its mechanical strength has been significantly enhanced compared to pure copper materials. Its tensile strength and yield strength have both shown a notable improvement.
C19160 Nickel Bronze can maintain good mechanical properties even at medium-high temperatures, and is less prone to softening or performance degradation. Even when used under long-term electrical conduction or heating conditions, it can maintain its structural strength and conductivity at the temperature.
C19160 Nickel Bronze is less likely to suffer severe wear under frequent contact, friction, or plugging conditions. At the same time, its fatigue resistance performance is stable, and it can withstand repeated stress without cracking or failure, making it suitable for components that require long-term cyclic operation.
This C19160 Nickel Bronze has good plasticity and processing adaptability, allowing for various cold processing techniques such as stamping, bending, and stretching. It is also suitable for precision machining. During the processing, it is less likely to cause cracking or uneven deformation, which is conducive to improving production efficiency and ensuring product dimensional accuracy.
