UNS C84400 Bronze is a standard bronze alloy that meets the UNS (Unified Numbering System) C84400 specification. This alloy is composed mainly of copper (Cu), tin (Sn) and lead (Pb), with small amounts of other elements such as zinc (Zn) and phosphorus (P).
UNS C84400 bronze has a typical composition of approximately 81% copper, 7% tin, 3% lead, and 9% zinc. This alloy offers a good combination of strength, hardness, and machinability. Furthermore, the lead content improves the lubricity and slipability of the alloy.
Brinell hardness 55 HB
Elongation in 5.08 cm of 16%
Tensile strength of 2,000 kg/cm2
UNS C84400 bronze is used in a wide range of applications, including machine components, bearings, bushings, valves, threaded connections, and castings. Its strength, corrosion resistance, and ease of machining make it suitable for various industries such as automotive, marine, and general industry.
