Phosphor Bronze Hollow Round Bar
Manufacturer,Stockist and Exporter of Phosphor Bronze Hollow Round Bar
Phosphor Bronze Hollow Round Bar is a high-performance alloy product manufactured from copper, tin, and phosphorus. It is renowned for its excellent combination of strength, corrosion resistance, and wear properties, making it suitable for diverse industrial applications.
Sumer Metal Industries Private Limited is a leading manufacturer, supplier, and exporter of Phosphor Bronze Hollow Round Bars. With years of expertise, the company ensures superior quality and timely delivery to clients worldwide.
The company exports these hollow round bars to multiple countries, including Oman, Qatar, Saudi Arabia, the UAE, Kuwait, Spain, Germany, the USA, Canada, and several regions across Africa.
The bars are composed of copper, tin, and a small percentage of phosphorus. This unique chemical composition enhances wear resistance, fatigue strength, and corrosion resistance.
The common grades of phosphor bronze used are C51000 and C51900, each offering specific mechanical and chemical properties tailored for different industrial needs.
Phosphor Bronze Hollow Round Bars exhibit high tensile strength, good elongation, and excellent hardness. These mechanical properties make them ideal for manufacturing bearings, bushings, and precision components.
These bars are highly resistant to corrosion in both freshwater and marine environments, ensuring durability and long service life in challenging conditions.
Sumer Metal Industries provides hollow round bars with polished, machined, or as-drawn surface finishes, depending on client requirements.
The bars are available in diameters ranging from 10 mm to 200 mm, with wall thicknesses between 2 mm to 25 mm and lengths up to 6 meters, offering flexibility for custom applications.
The density of phosphor bronze is approximately 8.8 g/cm³, and it has a distinctive reddish-brown metallic sheen, making it visually appealing for decorative as well as functional applications.
