CuSi3Mn1 alloy

CuSi3Mn bronze strip is a solid section made of silicon-manganese bronze. Technical conditions for a manufacture silicon-manganese bronze sheets of grade CuSi3Mn1 are specified by GOST 4748−92. Chemical formula — CuSi3Mn1. CuSi3Mn1 is alloy of tinless bronze. It is resistant to corrosion, has good mechanical properties. Si (silicon) and Mn (manganese) (silicon-manganese bronze) are present in composition of bronze alloy. Furthermore, Zn, Fe, Ni, Sn, Pb are also present in a composition of bronze alloy CuSi3Mn1. It is necessary to do an additional heat treatment in order to make a sheet of bronze alloy CuSi3Mn1 more consistent. Silicon-manganese bronze can be pressure-treated.
