The effects of Al and Sn on the microstructure

corrosion and cutting performance of regenerated bismuth brass were investigated by adding different amounts of aluminum and tin in bismuth brass with the help of scanning electron microscope（SEM）

energy spectrum analyzer（EDS）

electrochemical corrosion

brass dezincification corrosion and drilling test. The results show that the corrosion resistance of bismuth brass is improved obviously by adding a small amount of Al

and the cutting performance of the material is weakened gradually with the increase of Al content. When Sn element is added alone

the corrosion performance of the material is increased with the increase of Sn content

while the cutting performance of recycled bismuth brass is decreased firstly and then increased. When the Sn content is 0.5%

the cutting behavior is the worst.
