Tin bronze casting alloys typically consist of copper as the major component, making up around 85-90% of the alloy. The addition of tin comprises about 5-12% of the alloy composition. In some cases, small amounts of other elements like zinc, lead, or phosphorus may be present to further enhance specific properties.

Tin bronze alloys offer good mechanical strength and toughness, making them suitable for various load-bearing components and parts subjected to mechanical stresses.

Tin bronze alloys exhibit excellent corrosion resistance, making them suitable for applications in marine environments, where exposure to seawater and moisture can cause rapid corrosion of other metals.
