Tin bronze is a copper-tin alloy with tin as the main element,Tin Bronze also known as tin bronze. When the tin content is less than 5~6%, tin dissolves in copper to form a solid solution,Tin Bronze and the plasticity increases. When the tin content is greater than 5~6 %,Tin Bronze due to the presence of a Cu31sb8-based solid solution,Tin Bronze the tensile strength decreases, so the tin content of the scaled tin bronze is mostly between 3~14%.
When the tin content is less than 5%, it is suitable for cold deformation processing. When the amount of tin is 5~7%, it is suitable for thermal deformation processing. When the tin content is greater than 10%,Tin Bronze it is suitable for casting.
Since a is similar to & electrode potential,Tin Bronze and the tin in the composition forms a dense tin dioxide film after nitriding, the corrosion resistance of the atmosphere and seawater is increased,Tin Bronze but the acid resistance is poor. Because tin bronze has a wide crystallization temperature range and poor fluidity,Tin Bronze it is not easy to form concentrated shrinkage cavities,Tin Bronze and it is easy to form dendritic segregation and dispersed shrinkage cavities.
The casting shrinkage rate is small,Tin Bronze which is conducive to obtaining castings with a size very close to the mold,Tin Bronze so it is suitable for casting The shape is complicated. The condition of large wall thickness is not suitable for casting castings that require high density and good sealing.
