WebYield strength of aluminium bronze – UNS C95400 is about 250 MPa. Yield strength of tin bronze – UNS C90500 – gun metal is about 150 MPa. Yield strength of copper beryllium – UNS C17200 is about 1100 MPa. The yield point is the point on a stress-strain curve that indicates the limit of elastic behavior and the beginning plastic behavior.

WebBronze is also the preferred metal for bells in the form of a high tin bronze alloy known colloquially as bell metal, which is about 23% tin. High tin bronze alloys are typically found in also gears as well as high-strength bushing and bearing applications where high strength, and heavy loads are present. Other applications for these alloys are pump impellers, …
