Phosphor Bronze 510 (PhBz 510) Small Diameter Tubing

Phosphor Bronze 510 (PhBz 510) Small Diameter Tubing

High Strength, Excellent Fatigue Resistance & Corrosion Protection — from International Tube

At International Tube, we produce precision Phosphor Bronze 510 (UNS C51000) small diameter tubing, a high-performance copper-tin-phosphorus alloy engineered for superior spring properties, fatigue resistance, and corrosion performance. With a typical composition of 95% copper, 5% tin, and a small amount of phosphorus for deoxidation, PhBz 510 is widely used in applications that demand dimensional stability, durability, and long-term performance.

Phosphor Bronze 510 is known for its exceptional cold workability, moderate strength, and excellent wear resistance, making it a preferred material in electrical, mechanical, and marine environments. Its inherent ability to resist stress corrosion cracking, along with outstanding solderability and formability, makes it a go-to alloy for engineers and designers alike.

PhBz 510 Tubing Features & Applications

At International Tube, our PhBz 510 tubing is trusted in high-reliability systems that require resilience, conductivity, and precision formability. Common applications include:

• Electrical connectors and spring contacts

• Marine and corrosion-prone mechanical systems

• Bushings, bearings, and wear-resistant sleeves

• Instrumentation and control systems

• Medical and dental device components

• Precision washers and flexure components

• Aerospace and defense electrical assemblies

Our small-diameter PhBz 510 tubing is manufactured using high-quality strip stock, plug drawn in coil form, and annealed as needed to meet specific temper or strength requirements. Tubing is offered in both straight lengths and continuous coil form, suitable for automated manufacturing and fine-detailed assembly.

When your project demands a balance of strength, resilience, and fine detail fabrication, International Tube delivers Phosphor Bronze 510 tubing with the performance and reliability your critical systems require.
