introduction
Bronze 544 in CNC Machining
Bronze 544, also known as "B-2" bronze or C54400 Phosphor Bronze, is a great choice for bearings due to its high machinability and wear resistance.
It is a corrosion-resistant copper-tin alloy, highly durable against high temperatures, seawater, and corrosive environments. It's a practical choice for demanding environments like those at sea or in harsh industrial settings. So, it is commonly used in components like valve bodies, pump shafts, and marine propellers. This bronze alloy is recognized for its toughness and fine-grain structure. With a machinability rating 80, it is also particularly suitable for electrical applications that demand high strength. Bronze 544 is made mostly of copper, with 0.50–11.00% tin for better corrosion resistance and strength, and 0.01–0.35% phosphorus to enhance wear resistance and stiffness.
Bronze 544 has impressive heat resistance, functioning well in temperatures from -50 to 500 degrees Celsius. It can undergo meticulous heat treatment to enhance properties like strength, toughness, and corrosion resistance, ensuring resilience without brittleness even after multiple cycles. It can be easily bent, formed, blanked, and stamped when annealed. Bronze 544 exhibits good suitability for brazing and cold working, with a fair rating for butt welding. However, it is not recommended for coated metal arc welding, gas-shielded arc welding, oxyacetylene welding, seam welding, and spot welding.
