Introduction
There are many different types of copper alloys as copper is a very ductile and malleable metal. UNS designations C90200 to C94500 indicate tin bronzes and leaded tin bronzes. These are ell known for their corrosion resistance property. Tin bronzes have better ductility and strength than semi-red and red brasses. Lead plays an essential role in these alloys it enhances pressure tightness and machinability.
The following datasheet discusses the chemical composition and properties of copper UNS C92210.
