Isis Metals is dedicated to precision manufacturing, ensuring reliable performance and consistent material integrity in every item they produce. With a strong focus on quality and customer satisfaction, Isis Metals delivers Phosphorous Bronze Bars and Rods that adhere to international standards, providing outstanding value for a range of engineering and industrial applications.
Phosphorous Bronze Bars and Rods are primarily made up of copper, tin, and a small amount of phosphorus. Typically, the alloy consists of 88–95% copper, 5–10% tin, and up to 0.5% phosphorus. This specific blend boosts strength, fatigue resistance, and corrosion protection. The material showcases high tensile strength ranging from 350–600 MPa, along with excellent elasticity and superior hardness. Its low friction coefficient and great machinability make it ideal for precision components. Moreover, it performs exceptionally well under fatigue, impact, and wear conditions, even in harsh marine or corrosive environments.

Phosphorus bronze bars can be welded, but it requires care. The material tends to be brittle at high temperatures, so preheating and using appropriate filler materials are recommended for successful welding.
To select the right phosphorous bronze bar, consider factors such as tensile strength, corrosion resistance, conductivity, the specific environmental conditions, required durability, and mechanical properties for your application.

Phosphorous bronze rods are available in diameters ranging from 1/8" to 12" and lengths up to 20 feet. Finishes include hot-rolled, cold-rolled, extruded, polished, and custom-machined.
Phosphorous Bronze Bars and Rods are extensively utilized in mechanical, electrical, and marine industries thanks to their durability and resistance to corrosion. They are commonly found in the production of bushings, bearings, pump parts, valve components, gears, and shafts. The alloy’s high fatigue strength and wear resistance make it perfect for heavy-duty mechanical systems. In electrical applications, it’s used for connectors, terminals, and springs due to its excellent conductivity and resilience. Additionally, it’s also employed in musical instruments, marine hardware, and precision engineering components that require both strength and reliability.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
