C51000 phosphor bronze CNC parts are precision-engineered components manufactured from C51000 alloy, a tin bronze with excellent spring properties, fatigue resistance, and wear characteristics. This copper-tin-phosphorus alloy (Cu-Sn-P) contains approximately 5% tin and 0.2% phosphorus, providing an optimal balance of strength, elasticity, and corrosion resistance. With a phosphorus content that acts as a deoxidizer, C51000 bronze offers superior mechanical properties compared to regular bronze alloys.
Our advanced CNC machining capabilities enable us to produce custom C51000 phosphor bronze parts with exceptional precision and tight tolerances. The material's excellent fatigue resistance and spring properties make it ideal for applications requiring repeated flexing or elastic deformation. The alloy's self-lubricating properties and low coefficient of friction make it perfect for bearing and bushing applications where wear resistance is critical. Our experienced engineering team works closely with you from design to delivery, ensuring your parts meet exact specifications while maintaining the material's superior mechanical properties.
We offer comprehensive surface finishing options for your C51000 phosphor bronze parts, including polishing for enhanced aesthetic appeal and reduced friction, nickel plating for improved corrosion resistance and hardness, and passivation for increased oxidation resistance. With no minimum order quantity and fast delivery, we're ready to meet your production needs, whether you require a single prototype or high-volume production of precision bronze components for springs, bearings, bushings, electrical contacts, or wear-resistant applications.

C51000 phosphor bronze contains tin (5%) and phosphorus (0.2%) which gives it excellent spring properties, fatigue resistance, and wear characteristics. The phosphorus acts as a deoxidizer, improving strength and corrosion resistance while maintaining good conductivity.
We have no minimum order quantity. Whether you need a single prototype or thousands of production parts, we can accommodate your requirements with the same level of precision and quality.
Prototype orders typically ship within 3-5 business days. Production orders usually take 7-14 days depending on quantity and complexity. Expedited options are available for urgent requirements.
Phosphor bronze has excellent fatigue resistance and spring properties, maintaining its elasticity even after repeated flexing cycles. It can withstand millions of flex cycles without failure, making it ideal for spring applications.
Yes, C51000 phosphor bronze is excellent for bearing applications due to its self-lubricating properties, low coefficient of friction, and excellent wear resistance. It's commonly used for bushings, thrust washers, and bearing sleeves.
