Brass 220 Chemical Composition

The main elements present in UNS C22000 are copper (Cu), lead (Pb), zinc(Zn), and tin (Sn). The chemical composition of this alloy includes 67% copper, 28% zinc, 5% lead, 0.25% tin, and other trace elements such as iron (Fe), manganese (Mn), nickel (Ni), sulfur (S) and phosphorus(P). These elements combine to create an alloy highly resistant to corrosion from most acids and alkalis at room temperature.

Bronze UNS C22000 Physical Properties

Bronze 220 has a melting temperature of 930°C (1706°F) and a density of 8.8 g/cm3. It is classified as an alpha-beta brass because it contains both alpha (α) and beta (β) phases in its microstructure. The hardness range is between 70 to 95 Brinell (HBW), with a tensile strength of 600 MPa (87 ksi). It exhibits good wear resistance thanks to its high lead content, making it an ideal material for bearings and bushings.
