CuSn4Zn4Pb4 - UNS.C54400 Free Cutting Phosphor Bronze Alloys C54400 Details & Applications: C54400 Free Cutting Phosphor Bronze CuSn4Zn4Pb4 - UNS.C54400 Phosphor Bronze Alloys, is a multi-alloy phosphor bronze containing 4% tin, 4% zinc and 4% lead, is the finest bearing alloy that the industry has to offer, it is a lead-containing multi-alloy bronze exhibiting a very good machinability, it is furthermore distinguished by its excellent spring properties. C54400 is used for electrical contacts which have to be manufactured as turned part. C54400 can be work-hardened up to 800 N/mm2 and therefore if of considerably higher strength than lead-containing brass alloy. When annealed, this metal can be bent, formed, blanked, and stamped. Typical Application for C54400 Phosphor Bronze Alloys Electrical: Electrical Connectors Industrial: Cam followers, Bushings, Gears, Pinions, Shafts, Valve Parts, Sleeve Bearings, Thrust Bearings, Screw Machine Products, Bearings, Thrust Washers Marine: Marine Parts Available Sizes: Custom Diameter & Sizes, Random Mill lengths Available Products (forms): Round bars, Flat bars, Square bars, Round Wires, Round Strips Custom shapes are available upon request.
