The condensation scale of tin bronze is large, and the dendrite segregation is severe; it is not easy to form condensed shrinkage holes during condensation, and the volume shrinkage is very small; the reverse segregation of tin is easy to appear in the ingot, and white mottled (8-phase precipitation) can be seen on the surface of the ingot in severe cases. , and even show tin-rich particles, generally known as tin sweat. Improving casting methods and process conditions can reduce the degree of reverse segregation; in liquid alloys, tin is prone to form hard and brittle inclusions SnO2, and smelting should be fully deoxidized to prevent inclusions. The mechanical properties of the alloy decrease; the sensitivity to overheating and gas is very small, and it can be welded and brazed well; no spark occurs during impact, no magnetism, cold resistance, and some wear resistance.

High-lead bronze bronze is an alloy that was used early in history. It originally referred to copper-tin alloy. Because of its blue-gray color, it was called bronze. In order to improve the technological properties and mechanical properties of the alloy, other alloying elements, such as lead, zinc, phosphorus, etc., are also added to most bronzes. Because tin is an element, many tin-free Wuxi bronzes are also used in industry, which are not only cheap but also have the required special properties.
