Product Overview Phosphor Bronze Alloys are copper alloys that incorporate tin and a small amount of phosphorus, providing exceptional strength, wear resistance, and fatigue durability. These alloys are known for their excellent elasticity, making them ideal for parts that undergo repeated stress. Common grades like C51000, C52100, and C52400 deliver reliable performance in applications where durability and stability are critical, such as electrical connectors, industrial springs, and bushings. Available Grades C51000 – Known for its combination of strength and flexibility, suitable for springs, connectors, and other dynamic components. C52100 – Offers higher strength and excellent fatigue resistance, making it ideal for high-wear applications. C52400 – Known for superior corrosion resistance, used in marine environments and industrial applications. Key Properties High Fatigue Resistance: Provides long-lasting performance in components that undergo continuous stress. Excellent Corrosion Resistance: Performs well in harsh environments, including marine applications. Good Strength and Elasticity: Combines tensile strength with flexibility, making it ideal for springs and flexible connectors. Wear Resistance: Phosphorus enhances durability, allowing for prolonged use in abrasive conditions. Ease of Solderability: Easily soldered, offering flexibility in electronic and mechanical applications. Applications Phosphor Bronze alloys are widely used across various industries for their strength, durability, and resistance to corrosion and wear: Electronics: Springs, connectors, and switch contacts requiring conductivity and flexibility. Automotive: Bushings, bearings, and parts subjected to friction and wear. Marine: Corrosion-resistant components for seawater environments. Industrial Equipment: Gears, fasteners, and valves for high-stress applications. Aerospace: Components needing consistent performance and resilience in dynamic settings.
