Overview

ZCuPb15Sn8 casting lead bronze tin bronze has a large solidification range and dendritic segregation; It is not easy to form concentrated shrinkage pores during solidification, and the volume shrinkage is very small; Reverse segregation of tin is prone to occur in ingots, with white spots (8-phase precipitation) and even tin rich particles appearing on the surface of the ingot during casting, commonly 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. Smelting requires sufficient deoxidation to prevent a decrease in the mechanical properties of the alloy caused by inclusions; Regarding overheating and
