QSn4-4-2.5铜板 铜棒 易切削性锡青铜
QSn4-4-2.5 tin bronze to add zinc, lead, tin bronze alloy elements, can be cutting, easy to welding and brazing, in the atmosphere, fresh water has good corrosion resistance, can only under the cold pressure processing, easy cause heat brittle due to lead hot working. Used to make the friction work under the conditions of bearings, bushings, bushing, disc and bushing inside the mat etc.
