Tin bronze plate is very resistant to corrosion in the atmosphere, sea water, fresh water and steam, and is widely used in steam boilers and marine ship parts. The solidification range of the tin bronze plate is large, and the dendrite segregation is serious; it is not easy to form concentrated shrinkage holes during solidification, and the volume shrinkage is very small. Reverse segregation of tin is easy to occur in the ingot. In severe cases, white spots can be seen on the surface of the ingot, and even tin-rich particles appear, generally called tin sweat. Improving the casting method and process conditions can reduce the degree of reverse segregation.
In liquid alloys, tin is easy to form hard and brittle inclusions SnO2, and the smelting should be fully deoxidized to prevent the reduction of mechanical properties of the alloy caused by inclusions. Very little sensitivity to overheating and gases, good for welding and brazing. No spark occurs when impacted, non-magnetic, cold-resistant, and extremely wear-resistant.
With the development of modern technology, it is difficult for a single metal to meet the material needs of modern high-tech production. Therefore, it is necessary to develop the connection between materials and integrate the excellent properties of different materials to meet the needs of industrial production. The connection of tin bronze plate to steel is one of them. Tin bronze plate has good corrosion resistance and high wear resistance and lubrication performance, and is often used to manufacture bearing components. In many industrial manufacturing activities, tin bronze plays an important role in determining work performance.
The widely used fusion welding method is difficult to weld steel and tin bronze, because the melting and burning of copper alloy elements will occur during welding, thereby forming pores in the weld, thereby reducing the performance of the work. Therefore, the diffusion connection is generally selected in the connection method. By verifying the selection of the diffusion connection technology and process parameters, the work can be done well. Tin bronze plate is a non-ferrous metal alloy with the smallest casting shrinkage, which can be used to produce castings with complex shapes, clear outlines and low air tightness requirements.
